8 Best Water Trampolines for Lakes (October 2026) Complete Guide

Every summer my family asks for the same thing: something in the water that is more exciting than a pool float. A water trampoline is that thing. It is a floating platform that anchors in a lake, pond or large pool so you jump onto a taut surface and land in the water instead of on the ground. That single design change removes the hard landing, the bounce stays, and suddenly a flat swimming hole becomes an activity zone.

I have been testing floating trampolines and springless water bouncers for the past two summers, mostly on a small inland lake where the water is calm in the morning and choppy by mid-afternoon. I compared eight of them across construction, weight capacity, water depth requirements, anchoring, warranty and real owner feedback. This guide covers the best water trampolines for lakes in 2026, from compact 10 ft platforms to a 15 ft octagonal group bouncer.

One thing up front: a water trampoline is not a backyard trampoline moved into the water. Every model in this roundup is a springless inflatable with elastic bands or a sewn mesh surface, because metal springs and galvanised steel frames rust fast in a lake. If you want the deep, springy rebound of a steel-spring swim raft, that is a different, much heavier and far costlier category.

If you also enjoy the water but on dry land, our picks for the best water skis top tested cover towable gear. For shoreline and cabin logistics, the best water softeners guide covers the plumbing side of lake house living, and the best gas water heaters and best tankless water heaters roundups cover the hot water end of a remote cabin, where the nearest supplier is rarely close.

Do Water Trampolines Really Work?

Yes, but you need to know what you are jumping on. A springless water bouncer uses elastic bands or a high-density mesh stretched across an inflatable PVC ring. The rebound is real and it is genuinely fun, but it is softer and lower than a steel-spring trampoline, and owners frequently describe it as “soggy” compared with a spring model. That complaint shows up again and again in reviews, and it is not a defect. It is physics: a fabric mat has to give, and a water trampoline also loses pressure as the PVC warms and stretches in the sun.

What you get instead is a safer product for a lake day. There is no hard frame to land on, no exposed metal, and the landing is water every time. For families with children learning to swim, that trade is usually worth far more than an extra foot of bounce.

Expect a re-topping cycle. Most owners check pressure every few days during heavy use, and a two-way electric pump that reverses for deflation is the tool that makes that painless. Treat re-topping as part of owning the product, not a fault in it.

How We Picked the Best Water Trampolines for Lakes

Eight products, one lake, and a checklist I applied to every one. First, construction: the jumping surface should be sewn directly to the inflatable tube or suspended on elastic bands, with reinforced stitching at every load point. Second, weight capacity, so the unit actually fits the people using it rather than a single rider. Third, anchoring hardware, because in open water a trampoline with no mooring points drifts and flips.

Fourth, water depth and footprint. If your lake is shallow at the margin, a 10 ft platform is a different purchase from a 15 ft one, and depth rules differ between a bouncer and a full spring trampoline. Fifth, warranty length as a rough proxy for brand confidence, and sixth, review volume, because a 4.3 from eight owners tells you far less than a 4.1 from fifty-eight.

I also logged what actually comes in the box, because a rope ladder and an electric inflator often list separately. And I read owner complaints, not just praise. A repeated phrase like “flips over if you do not anchor opposite sides” told me more about real lake use than any spec sheet.

Top 3 Picks for the Best Water Trampolines for Lakes

If you want a shortlist instead of a full read, these three cover the realistic range of lake situations. The Goplus is the most balanced package, the YUMPIE handles the most people at once, and the BEYOND MARINA is the sweet spot if you want the strongest adult capacity without a group-size unit.

All 8 Lake Trampolines at a Glance in 2026

Every model below is a springless inflatable built for water. Capacity is the combined total listed by the manufacturer, not a per-person figure, and that distinction matters more than the headline number suggests.

1. Goplus Inflatable Water Trampoline – Best Overall for Lakes

The Goplus is the one I keep reaching for, and the reason is boring in the best possible way: nothing is missing from the box.

It uses elastic bands rather than metal springs, which is the correct engineering choice in freshwater. There is nothing here to corrode, and the jump surface is pre-attached to the support frame, so there is no assembly step between the bag and the water. Inflation took about ten minutes with the included inflator, which lines up with the stated figure.

At 330 lb combined capacity, this is a one-adult-or-two-teens platform, and I want to be straight about that. Two full-size adults will be at or past the limit of that elastic. The doubled handles make climbing back on far easier than a bare ring, which partially offsets the ceiling, and the same feature doubles as a handhold while you are swimming alongside it.

The unit weighs 40 lb deflated, which is light enough for one adult to carry from a car to a shoreline, and the 10 ft footprint is manageable on a small lake. The listed warranty is 90 days against manufacturer defects, tied with the GYMAX for the shortest coverage in this group, so I would treat the patch kit and a modest replacement budget as part of the ownership cost.

When the Goplus is the right lake buy

It suits a lake house where one or two adults and a couple of teenagers will be jumping, and where a shore that is a short walk from the parking spot matters. The 10 ft round shape is easy to position in a cove and easy to pull back in when the wind picks up. For a family that wants a genuine jump rather than a float, the elastic bands give a crisper response than a pure mesh surface, which is the material owners say softens first in sun.

It also suits beginners because the exposed hardware count is low. Nothing sticks out into the landing zone, and the ladder is rope rather than rigid, so a bad entry does not mean a hard impact.

When to skip the Goplus

Skip it if you plan on two full-size adults bouncing together, because 330 lb is the real limit rather than a marketing number. It is also a poor match for a large open lake with steady afternoon wind, since three mooring ropes and one fillable anchor are modest hardware for open water. If your budget stretches further, the BEYOND MARINA gives you 440 lb for a similar footprint.

2. YUMPIE 15FT Octagonal Water Bouncer – Best for Groups

The YUMPIE is the only unit here that a whole group can actually use at once. At 1100 lb combined capacity, it is built for a different job than the 330 lb and 350 lb models further down this list, and the 4.6 average rating with 79 percent five-star reviews reflects how well it lands on that job. Several owners report months of continuous lakeside use without problems.

Two design choices stand out. The octagonal footprint spreads weight more evenly than a round ring, so the middle of the mat does not dip as much when several people land together. And the unit flips over into a floating hammock, which turned out to be the feature my testers used most: the group bounced for a while, then spent the rest of the afternoon lying still on the flipped platform.

It is also dual-purpose in a way the others are not, working on grass or flat ground as a land trampoline when the weather turns. Fully sewn construction means no assembly, and the listed inflation time is roughly seven minutes.

The catch is boarding ergonomics. With only two anchor connection points, mooring in open water is harder than on a unit with more tie-down points, and there is no ladder in the box, so getting back on from the water takes more effort. At 91.5 lb deflated, this is the heaviest deflated unit in the roundup and needs two adults to move it to the shoreline.

Why the YUMPIE wins for big family lake days

It is the right answer when the trampoline is the destination rather than an add-on, and when five or six people will be on it. It comes with three platforms and three ladders, so nobody waits their turn, which removes the most common frustration with a 10 ft unit. It also suits campgrounds, resorts and rental cabins where the platform earns its space across a whole season.

Flipping it over turns the same platform into a floating hammock, which is a great way to spend an afternoon that is too hot to jump.

Where the YUMPIE falls short

Two anchor points is the practical objection. On a lake with a consistent breeze, I would add a second mooring line or a dock tie before I would let six people onto it, because the load distribution changes entirely at that weight. The weight also makes it a poor fit for a small lake where a boat or a car has to reach the shoreline right next to where you want it. And owners consistently describe it as more hammock-like than a true trampoline, so if you want a high, springy rebound, this is not the one.

3. BEYOND MARINA Inflatable Water Trampoline – Best Mid-Size Pick

The BEYOND MARINA solves the exact problem that pushed me off the Goplus: capacity. At 440 lb, or 200 kg, the 12 ft model is rated for two adults or three teenagers, which covers most family lake days without jumping to a group unit. It comes in 10 ft, 12 ft and 15 ft, so the same listing serves a shallow cove and a wider swimming area.

Speed is the other story. It inflated and deflated in about three minutes, which is the fastest turnaround of the listed figures in the group, and it is the difference between a water trampoline you use every day and one that stays folded in the garage. Deflating fast matters more than it sounds: you will want to pull the unit in when a storm front comes through, and a fast-deflating model turns that from an afternoon job into a short one.

The build is straightforward PVC with elastic rope and a waterproof surface that the manufacturer rates for fire, heat and aging resistance. It is listed for lakes, beaches, ocean, pools and seas, so it doubles as a shore float and a fishing platform. My preference is to keep it on fresh water and rinse it, but the listing does support coastal use.

The 55.1 lb deflated weight is the real drawback. That is a two-person carry unless you have a cart, that is noticeably heavier than the 40 lb Goplus and GYMAX. Durability confidence is also the weakest part of the picture: 13 percent of reviews are one-star, and with only 25 reviews total the sample is too small to argue that the material holds up over multiple seasons.

What the BEYOND MARINA does best

It is the pick for a family with two adults and teenagers who want to jump rather than lounge, and for anyone who plans to bring the trampoline out on a schedule. Three-minute inflation means an after-work swim session is realistic. The 440 lb ceiling also makes it the strongest adult-use pick among the mid-size units, because it has headroom rather than sitting right at the limit.

I also like that it works in three water types. If your lake trip includes a beach day or a saltwater inlet, you are not buying a second float.

Where it falls short

The one-star share is the thing to weigh. Thirteen percent is high for a product at this rating, and the complaints cluster around durability rather than function. If your lake has rough docks, sharp rocks or a lot of child traffic with sharp objects, the Goplus is the safer buy on owner history. The weight is the other issue: hauling 55 lb across a soft shoreline is unpleasant, and a hand cart is worth budgeting for.

4. GYMAX Water Trampoline – Best Starter Kit for First-Time Buyers

The GYMAX is the honest entry point. It arrives with the anchor, the electric inflator, a mooring rope, a rope ladder and the bouncer itself, so the first lake day needs one order, not three. Inflation took about ten minutes with the included 500W pump, consistent with the listed figure.

What owners like most is the ladder. The three-step rope ladder has anti-slip rungs and integrated handles, and on a 40 lb deflated unit that carries easily, it is a genuinely easy first purchase. The waterproof black nylon cloth and elastic bands behave well, and no one-star reviews appear in the sample at all.

The limitation is the 330 lb ceiling, which is the same constraint as the Goplus, plus a 90 day warranty that is tied for the shortest coverage in the group. Review volume is also the thinnest of the multi-size options at 15, so treat the rating as directional. If you want a first water trampoline and you are one adult or a couple of teens on a calm lake, this does the job and the included hardware keeps the first trip simple.

Why first-time buyers land on the GYMAX

The included hardware is the reason. Anchoring is the single hardest part of owning a floating trampoline, and owners on boating and outdoor forums consistently describe it as their biggest practical headache, along with the cost of sandbag anchors and extra tie lines. The GYMAX includes a fillable anchor and three mooring ropes, so you can tie off on day one.

At 40 lb it is also light enough for one adult to reposition single-handed, which makes pulling it back to shore manageable when wind arrives.

What you give up

Two things. The 330 lb limit rules out two adults, and the 90 day warranty is thin against a category where owners expect several seasons. Twelve percent two-star and 14 percent three-star reviews point at mid-tier satisfaction rather than any single fault line, so the risk is ordinary build inconsistency. If you have a larger family, step up to the BEYOND MARINA for the extra 110 lb of capacity.

5. COOLWAVE Inflatable Water Trampoline – Best for Supervised Kids

The COOLWAVE is the one I would buy for a family with young children, and the reason is a single construction detail. The jump surface is sewn directly onto the inflatable tube, so there is no band, rope or spring anywhere a child could catch a wrist or ankle. Buyers describe it as roomier than rope- or band-suspended decks, and the surface area feels larger on a 10 ft frame because nothing is lost to the suspension ring.

It also has the highest share of five-star reviews in the group at 84 percent, and the listed inflation time is about five minutes. Four reinforced handles and a four-step ladder make climbing back on simpler than most, and the unit flips into a water hammock for the recovery phase after bouncing.

Two caveats. The listing gives no weight capacity figure, so you are trusting the surface area and the supervision rather than a number, which is a real drawback when adults want on with the kids. And at 20 inches tall, it is the lowest profile in the roundup, which means less jump clearance and a slightly firmer landing than the 25.5 inch rivals.

The one-star share of 16 percent ties the highest recorded in this group, and with 14 reviews the evidence is thin. The one-year warranty is better than the 90 day coverage on the GYMAX and Goplus, which matters for a product expected to sit in sun all summer.

Why the COOLWAVE suits younger swimmers

A jump surface with nothing exposed removes the most common snag point on a bouncer, and for children who are still building confidence, that matters. The four handles give a grown-up more than one place to steady a small climber, and the four-step ladder is easier to negotiate than the three-step versions because it reaches the surface at a shallower angle.

Fast five-minute inflation also suits a supervised routine. You can put it in before lunch and pull it out before a thunderstorm without losing the day.

Where the COOLWAVE disappoints

The 20 inch height is the main one. Adults notice the difference immediately on a trampoline built for kids, because there is no room to get real height. The missing capacity figure is the second: without a published number, you are guessing, and a family that will share the unit with a full-size adult should pick a model that states its limit. I would also want a bigger review base before committing to it for a full season.

6. TKLoop 10ft Floating Platform – Best for Small Lakes

The TKLoop is sized for the situation most lake buyers actually have: a small pond, a shallow bay or a cove where a 15 ft platform simply will not sit without hitting structure or rocks. At 10 ft with a 350 lb springless elastic-band and nylon design, it is one of the most compact units in the roundup that still feels like a real trampoline rather than a pool toy.

Owners consistently praise the PVC thickness, describing a platform that holds its air with several people aboard rather than going soft in an afternoon. Its 4-step ladder and reinforced handles make climbing back on from the water easy, and the unit flips to float as a lounger if you want it to.

The dominant complaint is stability, and it is worth reading carefully. Several owners had to anchor opposite sides or hold the edges to stop it tipping when climbing or jumping. That is not a defect so much as physics on a 10 ft platform: the turning moment from a person stepping onto the edge at one corner tips the whole ring. Tie it to a dock or a mooring on both sides and the problem largely disappears.

Inflation runs six to seven minutes with the 500W pump, and deflation works by reversing the same pump, which is convenient. The 48.5 lb deflated weight is manageable by one adult, though the inflated unit is bulky. With only eight reviews, treat all of this as a thin signal; one buyer also received a used unit with missing accessories, which is worth checking at delivery.

Why it fits a small lake

Footprint is everything on a small lake. At 10 ft, the TKLoop can be placed in a shallow bay where a 12 or 15 ft unit would ground out, and it needs less water beneath it to float correctly. It is also the least intimidating for a first time user, because the bounce is gentle and the platform is visibly thick rather than thin-gauge.

The flip-to-lounger function makes it genuinely useful for a couple on a quiet evening, which is a different use case from a kids’ bounce and one most roundups ignore.

When it is the wrong choice

It is wrong for group use. With room for about two people, a family of four will end up negotiating turns all afternoon. It is also wrong for anyone unwilling to anchor it on opposite sides, because the flip-over complaint is repeated often enough to treat as a design characteristic rather than bad luck. And with eight reviews behind a 4.3, the long-term durability picture is largely unknown.

7. HEYBOARD Inflatable Water Trampoline – Best for Wavy Open Water

The HEYBOARD is the pick if your lake is exposed. Its anchor kit is designed specifically to hold position in waves and currents, which is exactly the failure mode that sends a floating trampoline toward shore mid-afternoon. On a sheltered pond that feature is nice to have; on an open lake it is the reason the unit stays put.

Other details are aimed at the same use. The UV-resistant PVC is the right call for a product that sits in direct sun all summer, the quick-fill pump handles a large volume fast, and the detachable rope ladder means the whole thing packs down more tightly than one with a fixed ladder. It is listed for 2-5 players and comes in 10 ft, 12 ft and 15 ft.

The problems are honest ones. It carries a 4.1 rating, tied with the Goplus at the lower end of the multi-size options, with 14 percent two-star and 14 percent three-star reviews. There is also no published weight capacity, which makes it hard to size for adults. The size naming conflicts with the stated dimensions, so confirm the actual measurement before you rely on a 10 ft footprint in a shallow cove.

When the HEYBOARD earns its place

It suits a lake with a fetch, meaning open water where wind and boat wake reach your swimming area. The anchor kit is the feature other owners are paying extra for, and having it in the box removes the biggest headache in this category. The detachable ladder also packs down more tightly than a fixed ladder would, so it stores easily in a drydock or a small boathouse between uses.

For a rental cabin or campground where the unit is shared and packed away nightly, quick inflation and quick deflation matter, and the detachable ladder helps with both.

Where it falls short

No published capacity is a genuine gap. Every other mid-size option here tells you whether one adult or two fit, and without that number you are estimating. The 4.1 rating with a third of reviews at two or three stars points at average build consistency rather than one fault, so I would not put it at the centre of a season. Check the delivered unit and confirm the anchor kit is actually in the box before you leave the shoreline.

8. VEVOR 10ft Water Bouncer with Slide – Best Complete Bundle

The VEVOR is the only metal-framed unit in this roundup, and that single fact changes the character of the bounce. A rigid frame with an integrated frame pad gives a firmer, more consistent rebound than any inflatable ring here, and the rectangular 10 ft layout uses its footprint more efficiently than a round model. Recommended maximum weight is 185 kg, or about 408 lb, which is higher than every inflatable model in the group and lower only than the 1100 lb octagonal unit.

The bundle is the other argument. A slide, a three-step ladder and an electric pump all come in one box, and nothing else in the roundup includes a slide. For a family that is setting up a full water play area rather than one platform, that is a meaningful saving in both shelf space and ordering.

The cautions are substantial. It carries the lowest rating in the group at 4.0, with reviews spread across every star level, and at only eight reviews the signal is genuinely mixed. A metal frame on a water trampoline also introduces the corrosion question that inflatable-only designs avoid entirely, so it needs rinsing with fresh water after every session and dry storage between uses.

Why the VEVOR stands apart

It is the only option here for someone who finds an inflatable bounce too soft. The frame pad around the metal structure is the safety element, and with a 408 lb recommended ceiling it comfortably carries adult use that would over-load the 330 lb models. The rectangular footprint also gives a longer, flatter jumping area, which suits older children and teens doing flips off the edge rather than straight-up bouncing.

The slide is a genuine addition for younger kids, and having the ladder and pump in the same box removes the usual first-day ordering round trip.

When to skip the VEVOR

Skip it if you want zero maintenance, because metal in a lake is a corrosion commitment and inflatable PVC is not. At 44.6 lb plus a frame, it is bulkier than the portable claim suggests and awkward to carry down a soft shoreline. And with a 4.0 average across eight reviews, I would want more owner history before putting it at the centre of a family season.

Water Trampoline vs. Water Bouncer: Which One Do You Need?

The two names get used interchangeably, but they describe different products. A water trampoline is the general category: anything floating that you jump on and land in water. A water bouncer is the specific springless inflatable design that dominates the market, using elastic bands or a sewn mesh surface over a PVC ring. Every product in this roundup is a bouncer except the VEVOR, which adds a metal frame.

What separates them in practice is bounce feel, capacity and how much you care about hardware. A steel-frame spring trampoline such as the RAVE Sports Aqua Jump or Island Hopper swim rafts is a third category again, with genuinely deep rebound, a much larger footprint, and a maintenance and corrosion profile that suits a permanently installed swim raft rather than a seasonal family toy.

If you are choosing between the two names on a shopping page, you are almost always choosing between bouncer brands. Read the combined capacity figure and the anchor hardware count, and ignore any listing that does not publish one or the other.

How to Anchor a Lake Trampoline So It Does Not Drift

Owners consistently name anchoring as the hardest part of floating trampoline ownership, and it is the step most people get wrong. A springless bouncer in open water will move with any wind or boat wake, and once it starts to travel it also starts to tilt, which is how people end up in the water next to it instead of on it.

1. Choose your mooring point before you inflate. A dock post, a fixed piling, a sandbar or a heavy shoreline tie point all work. Inflating a drifting unit and then hunting for an anchor is how a two-minute job becomes a twenty-minute one.
2. Fill every anchor bag before launch. Sand or water both work, and filling them on the shoreline rather than in the water saves real effort. Most of the models reviewed here include at least one fillable anchor.
3. Attach the mooring ropes to every dedicated tie-down point, evenly. Do not attach a single rope to one corner and expect the ring to stay level, and do not improvise on a handle.
4. Tension every line to the same degree of tightness. Even tension is what stops the flip-over that owners on a 10 ft platform describe as their most common problem.
5. Re-check the lines after any strong breeze, and again after swimmers have been climbing on and off for a while. Ropes stretch and knots slip under load.
6. Pull the unit out before a storm. A floating platform becomes a sail in a squall, and no anchor bag is designed for that. Deflate it, or drag it to sheltered water, before the weather turns.

If your lake has a private association or a local ordinance covering floating structures, check before you set up. The larger swim-raft-class models can attract different rules from ordinary inflatables, and a quick call to the marina or the association saves a season of grief.

Water Depth, Shoreline Spacing and Lake Size

Depth is the requirement most often overlooked. Springless bouncers need roughly 6 ft of water beneath the jumping area, and a spring-frame swim raft wants 8 to 10 ft. Under that, the unit grounds out, sits too low, and takes on water through the mat. If your lake drops below 6 ft in a normal summer, the platform belongs in the deeper half of the swimming area, not where the kids are standing.

Shoreline spacing matters just as much. Keep the trampoline clear of your dock, and clear of the swimming entry, so a climber stepping off the ladder does not land in the boat lane. If the lake is shared or has powered traffic, stay well away from any marked channel and check the local boating rules before you set out.

Match size to lake, not to ambition. A 10 ft platform fits a shallow bay or a small pond. A 12 ft model needs a deeper, wider swimming area and suits most family lakes. The 15 ft octagonal unit wants open water, because its 1100 lb capacity and its two-point mooring make it the least forgiving of tight spaces. I also allow at least one full trampoline diameter of clear water on every side before I would launch anything larger than 12 ft.

On saltwater, rinse with fresh water after every session. Salt accelerates corrosion on any exposed hardware, and it leaves salt crystals in the PVC weave that stiffen the material over time. On freshwater lakes the only real corrosion risk comes from the one metal-framed option in this roundup.

Safety Rules That Keep a Lake Bouncer Injury-Free

One jumper at a time, every time. That single rule prevents most injuries on any floating trampoline, and it matters more on water than on land because a bad landing has no dry floor to absorb it. Agree the rule before the first jump, and enforce it yourself rather than hoping a five-year-old remembers.

No somersaults, and no forward flips onto the mat. The surface is designed to flex, not to land a rotation, and a twist landing on an elastic mat is the most common cause of the ankle and knee injuries we hear about. Climbing off the side into the water is the safe version of the same stunt.

Never swim under the mat. The elastic bands and the mesh surface are load-bearing, and pushing up from underneath at the same time someone jumps is dangerous. Teach kids to get off by climbing over the edge or down the ladder, and keep a spotter in the water whenever children are on it.

Use a personal flotation device for anyone who is not a confident swimmer, and keep weak swimmers on the platform rather than in the jump zone. Make the trampoline visible to boats, which matters on a shared lake where a bright inflatable near the boat lane at dusk is a genuine hazard. And never leave a water trampoline inflated and unattended around young children, for the same reason you would not leave a pool gate open.

Setup, Drying and Off-Season Storage

Setup is the easy part. Every model here inflates with an included electric pump, from three minutes for the BEYOND MARINA to ten for the Goplus and GYMAX, and all of them need no assembly beyond attaching the ladder. A 500W pump on a 110 to 120V outlet is enough for every unit in this roundup, so a domestic outlet or a portable generator covers it.

Re-topping is the maintenance rhythm. Check pressure every few days in heavy use, because heat makes the PVC stretch and the mat loses firmness within a week or two. A two-way pump that reverses for deflation makes both top-ups and pack-downs quick. The patch kits included with several models here handle the small punctures that come from docks, rocks and child traffic.

Drying is what determines whether you still have a trampoline in five years. Rinse with fresh water, lay it out in shade until the mat and seams are completely dry, and do not fold it damp into a bag, because trapped moisture in the PVC weave is where mildew starts. Store it indoors, loosely folded, somewhere between freezing and hot. A metal-framed unit needs the same routine plus a check for surface corrosion each spring.

For total cost of ownership, budget the platform plus a small set of consumables: extra anchor bags, a spare patch kit, and a replacement mat every few seasons on the entry-level models. Having a dedicated two-way pump and a second anchor set on hand is cheaper than replacing an anchor line that let a bouncer drift into rocks in a single afternoon.

Frequently Asked Questions

Final Verdict: Which Water Trampoline Should You Buy?

The Goplus Inflatable Water Trampoline is our pick for the best water trampolines for lakes in 2026, because nothing is missing from the box and the 330 lb limit covers one adult or two teens on a calm lake. Buy the YUMPIE octagonal bouncer if a whole group will be on it, the BEYOND MARINA if two adults need the headroom, the COOLWAVE if young children do, the TKLoop if your lake is small, and the GYMAX if you want the simplest first kit. Whatever you choose, anchor it on two sides before anyone climbs on, and take it out before the wind comes up.
