Quick Overview

Availability: In stock



This Jumpking Rectangular Trampoline offers a professional-style jumping performance due to its shape and spring configuration. Unlike round trampolines the bouncer can jump anywhere on the jumping surface and get the same bounce as well as control where they land rather than being thrown to the centre.

If safety is a priority, which for most of us parents it is, then this is the trampoline for you. The Jumpking Rectangular trampolines boasts Jumpking's thickest frame yet ensuring optimum stability and strength.

Featuring a welded socket, the enclosure poles slot directly into the socket behind the legs thus removing the need for brackets and clamps! You have a great looking product that takes less time to assemble compared to other systems. The Jumpking Rectangular trampolines are backed by the Jumpking name; the biggest trampoline manufacturer in the world, with more worldwide sales than any other brand. The build quality of this trampoline is such that the manufacturer provides a very reassuring 10 year guarantee on the frame and 5 year guarantee on the bed and springs.

 Advantage Over Traditional Trampolines

  • Multiple jumping zones
  • Easy to attach the safety enclosure with the welded socket system
  • Easy maintenance, no nuts and bolts to re-tighten
  • More user control

Unique Innovation

  • Welded socket - the enclosure poles slot directly into the socket - No Brackets!
  • It looks great, with horizontal shock-corded poles to hold the enclosure in a rectangular form


  • The net uses the 'stitch-in' system for added safety
  • Fully fastened entry/exit door for maximum security
  • Complete peace of mind for the concerned parent
  • Conforms to all safety regulations and EN71-14 tested
  • Ladder included

We are pleased to offer reduced priced accessories when ordered with the trampoline. Please use the tick boxes above to make your selection

Trampoline tie down kit  

The trampoline tie down kit is becoming more and more popular. As our weather appears to be ever more changeable we are seeing increasing numbers of customers looking for replacement parts for trampolines that have flown over into next door's garden.

Trampoline speaker   Just put your iPod or other MP3 player into the casing and strap the speaker to your trampoline. Simple! You could also strap it to your garden furniture parasol, the handle bars on your bike or even use it in the shower (it is shower proof!)  NB these speakers can only be used with small MP3 players/phones.
Jumpking Rectangular Bed Cover   Our range of covers have a superb finish and fit on to the trampoline beds only. Therefore they are a suitable option for trampolines with enclosures fitted, allowing you to cover the bed of the trampoline without taking the enclosure off. Our covers provide protection from leaves, bird mess and other unwanted debris - as well as letting smaller members of the family know that the trampoline is out of bounds until Mum or Dad are around!

Shoe Store   This handy shoe tidy will help prevent young children tripping over discarded shoes around the trampoline, not to mention stopping the dog running off with your best trainers!



Please check out the wonderful customer videos below for an idea of how much fun you can have on one of these trampolines. However, please use the trampoline safely. Tricks and flips need to be learned with care, preferably under guidance from a suitable adult. Please also remember you should only have one user at a time on a trampoline.


We have the largest range of Jumpking trampolines available in the UK today. If we don't have a Jumpking Trampoline to suit you, no one will!

The Jumpking trampoline brand is the biggest in the world today and they have been making trampolines for approximately 50 years. Jumpking is the market leader with great trampoline innovations and the manufacturing facility now produces approximately 60% of the world's trampolines. As well as the highest standards of quality, Jumpking pride themselves on the continual development of their products, as can be seen by their huge range. Jumpking trampolines are all designed with safety as the first priority. All trampolines meet or exceed ASTM and TUV standards. Jumpking trampolines also come with a comprehensive range of accessories to add to the experience. Jumpking Trampolines provide fun, exercise, health, fitness and safety for the whole family. We at have been supplying Jumpking Trampolines since our very earliest days and due to our product knowledge and keen prices have become one of the most successful Jumpking retailers in the UK today.

Why buy a 'JumpPOD'?
All of our Jumpkings are PODs. They are the next generation Trampoline, providing two of the original trampoline products (trampoline and enclosure) and putting them together in one unit. Featuring the Tri-layer Socket, the enclosure poles slot directly into the trampoline top rail, completely removing the need for brackets. You have a great looking product that takes less time to assemble compared to any other system. Plus, the new Euro-Spring 'over and under' configuration reduces stress on the frame, increasing durability and optimising the jumping performance.

Jumpking OvalPOD Oval Trampolines
The Jumpking oval shaped trampoline was specially developed for the UK market. The Ovals combine the outstanding performance of a rectangular trampoline with the proven safety features of the best selling JumpPOD and here at we can offer you 5 different sizes of OvalPOD.

Jumpking Rectangular Trampolines
These brand new designs arrived in the UK May 2016 and have been hugely popular. As with indoor competition trampolines, the Jumpking Rectangulars have a 'sweet spot' in the centre but also offer an even controllable bounce across the entire bounce mat.

Appalling liars never to be trusted Hi RobertHaving reviewed your query, I can see that three boxes were despatched to you and just the two trampoline boxes were initially delivered.

Instructions are incomplete - several items were not shown at all, so you have to work out what they are meant to do at what stage. Some key things overlooked, like the importance of which way around some of the frame goes. One leg didn't seem to fit at all and we will need to drill our own screw hole... Read More. Hi

Thanks for your feedback.

We have passed your comments on to Jumpking and are working with them to see if there are any improvements we can make to the instructions.

You get what you pay for, this certainly isn't the cheapest trampoline but the quality is evident. I am thrilled with the trampoline as are my children. It is a fantastic size with excellent bounce and is very sturdy. Not disappointed and glad I spent that bit more for a decent trampoline.

Great size, sturdy, fairly easy to construct ( about 2 hrs). Only problem is the cords in the poles which thread through the top of safety net broke within 4 days. Quickly replaced by jumpking with no problem.
