Buyers Guide

Welcome to the Jump for Fun Trampoline Buyers Guide. We have compiled a guide examining the pros and cons of the different shapes in which trampolines are available to purchase. We hope this guide will answer any questions you have and help you in your buying decision.

Impartial Advice

The guides are not designed to be biased towards our products, they are here to help you whether it is advice on the pad, frame, warranty, spares or more. You will see various different guides across the internet and most are in line with our recommendations, some may vary a little but we do feel this guide is extensive enough to help. The information we have gathered comes from our vast experience of selling (and jumping on) various shaped trampolines ranging in quality.

Please take a short time to read through these guides as 10 mins of your time now WILL save you money at a later date. If you have any more requirements for information about our guide please give us a call on 02036375936.

Please follow the navigation below to select each of the buying guides to assist you in the choice of trampoline for you and your family.

Round Trampoline

Round trampolines have been the most popular choice of garden trampolines over the last 10 years. Round trampolines are great for one jumper as the design pulls the user into the middle where the bounce is at its optimum. Traditionally cheaper round trampolines have shorter and fewer springs to reduce costs, typically resulting in a poor quality of bounce.

Rectangular Trampoline

Due to the shape and spring configuration of a rectangular trampoline, individual springs work at a different rate which allows for a more powerful bounce. These trampolines are better for experienced bouncers who are possibly members of a trampoline club as this is where you will typically find rectangular trampolines. Club trampolines cost upwards of £1000. Cheaper rectangular garden trampolines are often built to a price budget and therefore have quite low specifications. These will not produce the performance you may expect.

Round Trampoline

A round trampoline will have every spring pointing right into the centre and makes the centre soft. When you move out from the centre, the bounce gets harder behind you. If you lose your balance or concentration you may be thrown forward off balance. Fifty percent of trampoline injuries occur when there is more than one person jumping, and on a round trampoline the risk of collision dramatically increases.

Octagonal Trampoline

Octagonal trampolines are much safer than the circular design. The design allows the jumper more control over their movements and unlike a round trampoline it does not pull the jumpers into the middle. This has proven to reduce accidents and trips to A & E. If fitted with the correct springs an Octagonal trampoline will far out perform a round trampoline with its superior bounce. In general octagonal trampolines with 7 inch springs are best suited for younger children as the bounce can be restricted unless a special spring is used. For a much improved performance search for an octagonal trampoline with 8 to 8.5 inch springs. For the serious trampolinist or heavy jumper you may wish to search for octagonal trampolines with springs 9 inch plus, however these will not be suitable for young children. Due to the design a larger octagonal trampoline will also fit into a space too small for a traditional round trampoline.

Round Trampoline

A Round trampoline has every spring pointing towards the middle of the jump mat and makes the centre soft. When you move out from the centre, the bounce gets harder behind you. If you lose your balance or concentration you may be thrown forward off balance. Fifty percent of trampoline injuries occur when there is more than one person jumping, and on a round trampoline the risk of collision dramatically increases.

Oval Trampoline

Like the Octagonal trampoline, the springs on an Oval Trampoline do not all point towards the centre of the jump mat, therefore users aren’t drawn towards the centre of the mat (round trampoline) making it safer for multiple jumpers. Despite the bounce being safer for multiple users, the narrow shape can make it quite claustrophobic and tight on jumping space. A pro for the Oval trampoline is that the shape allows the trampoline to fit into tighter spaces as they can be significantly more narrow than a traditionally shaped trampoline.

Trampoline Frame

The Top frame is the actual body of the trampoline, everything rests on this structure fitting correctly. The frame for the UK market should be galvanised inside and out with a steel thickness of between 1.5mm and 2.0mm.

Welded Trampoline Frame

Weld joints are the weak link as they are usually on the leg joints connecting to the body/top frame, we recommend buying a trampoline without any weld joints, this will stop any structural failure due to welding issues. Extra welded steel plates on a trampoline will not give it the protection that is required.

Trampoline Springs

You will be baffled on other websites by ” Extreme Springs ” or ” Super Strength Springs ” or even “Performance Springs ” etc etc. This is confusing and unnecessary. The frame and springs are the main parts of the trampoline. The frame is like a car body and the springs are its engine. The jump mat is polypropylene and needs to be of good quality and taut when on the trampoline with the srings. The springs have to be the correct length, diameter of wire and helical circumferences combining to create the perfect Newton strength and performance. All our trampolines are designed with this in mind.

Spring Ranges

Jump for Fun have a range of trampolines using between 7”, 8.5” and 9” springs, the rule of thumb is the longer the spring, the more body weight is needed to maximise the bounce. We do not recommend buying a trampoline with springs less than 7″ on a trampoline.

Trampoline Pads

This is an area that if you do a little home work it may save you quite a lot by not having to buy replacement pads after only a short while. Most pads look similar on websites so it is difficult to tell bad from good quality. Here are some points to look for:


Cheap trampolines will use poor quality pads; they have to do so to be cheap! These are quite often blue in colour. Normally covered in the cheapest material possible called Polyethylene or often shortened to PE. This type of covering will normally perish within a few months.

The majority of pads are filled with EPE foam despite how it is worded. Some very expensive pads did use EPA foam which was slightly better on impact but it was marginal and we believe they now use EPE too.

Cover Material

The foam can be covered in PVC, this is far better than PE but it can also crack. Polyester is better than PVC. Best of all is a rubber/plastic compound material. This has been known to last in excess of 10 years. Whichever material is used they should be UV stabilised as standard. Green is normally the colour of better quality padding.


Some brands will be very vague about the thickness as of course the thinner the foam the cheaper their costs.

Beware the term “double thickness”. This does not mean what you would assume. It means the padding over the springs is thin but is “double thickness” at the frame part. For example 6mm over the springs and 12mm over the frame edge. This is wholly inadequate for protection from the metal springs and frame. Some “double thickness” will be 10mm going up 20 mm, this is the bare minimum required. A solid block of foam in each section of the padding across the springs to the edge of the frame is much better and safer. Some paddings have each section broken up into smaller pieces of foam rather than one large piece of foam in each section. This can allow spaces to appear and also give a wavy appearance to the pad over time. Again this is cheaper to produce. 20mm to 40mm thickness is ideal all the way across the padding.


Lastly the fixing of the pad to the trampoline is very important. Beware elastic ties which are sewn on to the pad as these can break when the pad is lifted by the wind. This will leave you with no way of attaching the pad back on as the ties cannot be replaced, therefore your pad will be useless. The best method involves elastic straps and a toggle system which should be passed through a loop or through metal eyelets which is usually a sign of a good quality padding.

Most websites should show all the information mentioned above. If it doesn’t, beware. If still unsure it is best to pick up the phone and ask some questions. Don’t be surprised if the seller doesn’t know all the answers themselves. As stated earlier a little home work can save you a lot of money in the near future.

Trampoline Jump Mats

The Jumping mat is the surface that is used to jump on, this should be made from grade A Permatron polypropylene. The trampoline mat should be UV treated and a V ring connection to the trampoline spring is also recommended, other connection devises can get in the way of the jumper and can increase the cause of accidents.

Trampoline Warranty Guide

Trampoline Warranties can vary from manufacturer, and is based on the quality of materials used. As a guide we recommend a minimum of a 10 year warranty on the frame section with a minimum of 2 years on the springs, padding and jump mat. You will find some companies that offer a life time guarantee on their frames. Don’t forget that warranties are only as good as the longevity of the company you are buying from so do your best to ensure they are a company that has been trading for a long time already and are likely to be there in the future.

Spare Parts Guide

A reputable company can and will hold a complete set of spare parts for their trampolines, supported by a warranty and customer care service. If your supplier cannot offer warranty or spares, we would not recommend purchasing from them, unless they are a reseller of a reputable brand in which case you will be covered. There are currently only 6 recognised brands for sale in the UK. Also check the cost of the spares. The item which will probably need replacing first is the safety padding. A good quality polyester thick padding should cost in the region of £60 to £65 for a 14ft. A lot of parts are compatible between makes so you can shop around for the best quality along with best price. Be aware of brands where you can only buy spares from themselves, these can often inflate the cost of spares as they believe that you can not purchase them anywhere else. Also check that the netting part only of the enclosure is available by itself, you should not have to buy a complete enclosure when you do not need new poles. Check they carry spare parts of frame, if they don’t and your frame gets damaged by high winds then your trampoline is no longer of use. Spare poles for enclosures should also be available.

Jump Safe | Play Safe

The popularity of garden trampolines in the UK is still as high as ever and with this brings the potential for more accidents. Jump for Fun are committed to increasing awareness on the safe use of your trampoline. Jump for Fun are clear on the correct usage of trampolines in the garden and each one of our products comes pre-packed with a guide for installation and safety.

Round Trampolines

Jump for Fun only recommend ONE jumper at a time. Why?

Round trampolines tend to send the jumper back into the centre. More than one person jumping will increase the risk of collision as they are both bouncing towards the same area. A smaller child with less body weight is at the highest risk in this situation.

Octagonal Trampolines

Safer For More than one jumper. Why?

This is due to the design and the way the octagonal trampoline works. The jumper has more control over where they go on the trampoline and are not drawn into the centre each time they jump. Although we always recommend one jumper on a trampoline at any one time we know it is difficult to sometimes enforce on eager children. If you think that it is at all likely that you may have more than one jumper at a time using the trampoline we strongly suggest you visit our OctaJump range.

Safety Enclosures

Safety Enclosures help to increase safety. Why?

Installing a safety enclosure will dramatically reduce the risk of a child falling off their trampoline. 99% of all our trampolines are sold with a safety enclosure. There are two different types of safety enclosures on the market either the net fully encloses the trampoline around the circumference or it encloses the jump mat. But we believe through our experience over the last 10 years that by totally enclosing the trampoline with the net it keep the jumper safely inside and also prevents other children watching from climbing on to the padding around the outside of the net and being pushed off.

Tricks and Somersaults

A garden trampoline is designed with fun and exercise in mind and is not for professional use, if your child wants to learn more about trampoline skills we fully recommend that you enlist them into a local gymnastics club where they are supervised by a professional who can educate and teach the skill set necessary to accomplish complex manoeuvres on a professional trampoline ONLY.

Jump Safe : Play Safe

Jump Safe : Play Safe. Common sense safety rules are a requirement in all sports. A trampoline used properly and sensibly is excellent recreation – Jump for Fun recommends parental supervision at all times. Please follow the safety guide lines in the instruction booklet provided with the trampoline before using the product.
