The best trampolines should be easy to assemble and stable once built, whether they're 6ft or 10ft, rectangular or round. 

We've tested six of the most popular 8ft trampolines from top brands and retailers including Argos, Plum and Smyths to see which was the easiest to put together, as well as being safe and stable once built, with enclosures that were easy to take down on windy days. 

We tested trampolines of this size and shape as 8ft trampolines are among the most popular you can buy, and round trampolines outsell rectangular trampolines. Comparing like for like meant we could also be sure the pros and cons we discovered were down to brand, not shape or size.

How we tested trampolines

We tested trampolines that we bought ourselves from key brands and retailers. 

Ease of assembly/disassembly

Two testers assembled each trampoline and rated how easy each one was put together. 

We evaluated the usefulness of the instructions and supplied tools, as well as the force needed to put parts together, finger entrapment hazards, how easy the springs were to attach, how straightforward the enclosure was to assemble and how clearly parts were labelled.

In strong wind it's best to take the enclosure off trampolines, so we also looked at how easy it was to quickly detach and disassemble each trampoline's enclosure. 

Safety checks

Bouncing on a trampoline will always carry a level of risk, but the best models will minimise this. We checked each trampoline for the following:

Frame and enclosure height We made sure each trampoline met the required minimum heights (50cm for the frame and 150cm for the enclosure on 8ft trampolines).

Finger entrapment We used a 7mm rod, representing the size of a child's finger, to make sure it couldn't fit through the enclosure's safety net.

Enclosures We checked there were no blind spots on the enclosure, so you could see and supervise your kids no matter where you were located. We also checked whether the opening was clearly highlighted and an adult was able to fit through. 

Durability We placed 150kg on each trampoline mat for 10 minutes. Afterwards we examined each spring for signs of permanent deformation, and checked that the frame padding still covered all the springs.

Warnings Trampolines are required to have certain warnings in their instructions and on the trampoline itself. We checked that they were all there. 

All the trampolines we tested passed these checks. 

Stability checks

Which? best trampoline testing tester bouncing on Sportspower 8ft trampoline

We checked each model's stability by placing 110kg (around the weight of two adults) on the edge of the trampoline's frame to see if it tipped over. We also checked that the trampoline's legs couldn't be easily pulled out when lifting the frame, and four testers bounced on each trampoline to see how stable it felt during use. 

A 60kg tester hung from the top of each enclosure to test its strength. Some barely deformed and remained stable, while others popped out of their connections to the enclosure support poles. 

How to buy the best trampoline

Follow what we've learned from our testing and you won't go far wrong.

Tools All the trampolines we tested came with the tools needed to assemble them, but the spanners and screwdrivers were small and difficult to use. Consider using your own tools that you're comfortable with to make assembly easier. A mallet is also handy in case any poles are a tight fit. 

Size Trampolines come in standard sizes, starting from 6ft and going up to 14ft. For spring-free trampolines the size options are different. Size is measured by the diameter of the jumping surface, and excludes the surrounding springs and padding, so take this into account when measuring the usable space in your garden. Also, the wider the trampoline, the taller it tends to be.

Padding The surrounding padding that covers the springs should be a decent thickness and resistant to rain. Open-cell foam will soak up water and rot, while closed-cell foam will last longer. The PVC covering (on both padding and the bounce mat) should be UV resistant, as prolonged exposure to sunlight could increase the risk of it perishing.

Metal frame A trampoline frame is constructed from hollow steel tubes. The thicker the poles, the stronger the frame, but it will also be heavier. You also want the poles to be galvanised, both on the inside and outside of the tubes, otherwise they're more likely to rust over time.

Safety netting Make sure the netting is made from a strong and durable material so it can withstand the weather as well as your kids bouncing against it. 

Number of springs The more springs there are on a trampoline, the bouncier it tends to be.

Positioning If you plan to leave the trampoline out when not in use, think about placing it where there isn't too much sun, as the PVC covering could degrade over time if left out in direct sunlight. Also make sure the trampoline is placed on soft ground such as a lawn or wood chip. If that's not possible, get shock absorbers for the base and crash matting to surround the trampoline. For larger trampolines, consider tying it down with an anchoring kit so it doesn't get caught up in big gusts of wind.  

Spring vs spring-free trampolines

Brands such as Springfree and Plum manufacture trampolines with fibreglass rods instead of springs. This, in theory, makes for a safer trampoline, as they eliminate the impact areas that can cause injury.

However, they cost significantly more to buy than regular spring-based trampolines. 

In-ground vs above-ground trampolines

In-ground trampolines have their advantages: they take up less space, they're less of an eyesore in the garden and might be safer as your kids can't fall off.

However, they require digging a big hole in the ground to fit them in - which can be as deep as 90cm for the widest trampolines. Additionally, you'll need to ensure proper drainage to prevent rusting and deterioration of the trampoline below the ground.

Trampoline safety

When buying a trampoline, look for one with a safety enclosure that runs along the inside of the mat, putting the netting between the bouncer and the springs. This minimises the chance of your child making contact with any of the hard frame materials.

We've tested trampolines to make sure they've been designed to be safe, but trampolining will always carry some risk, with the most common injuries being bruises and sprains. 

You should never leave your child unsupervised while they're using a trampoline, but remember that many accidents can still happen, so keep these other safety tips in mind:

Only allow one child on the trampoline at a time According to the Royal Society for the Prevention of Accidents, 60% of trampoline injuries occur when more than one person is using the trampoline at the same time.

No bouncing exits Don't let your little ones launch themselves off the trampoline on to the ground. This might seem obvious but it's a common cause for injury.

No somersaults Kids shouldn't attempt them unless they've been taught properly, otherwise the chance of landing badly is high.

Kids under six years old shouldn't use standard trampolines They should only use models that have been designed specifically for younger children. Kids under the age of six are not yet developed enough to handle the bouncing movement, and are therefore more susceptible to injury.

Check for wear and tear, especially after long periods of not being used If you're not using the trampoline much over winter, for example, you might wish to remove the mat and springs and store them away. If it stays up and out, check for signs of sagging, stretching and deterioration. Lift up the padding to check the state of the springs and for any signs of rust. Check the frame for any signs of bending or weld joints beginning to weaken.
