Trampolines: take the leap!


It's no secret that kids love jumping around So why not indulge them by getting a trampoline? Quick and easy structures to set up, you can choose from a range of sizes and find a model to suit your budget.

There is nothing terribly complicated about the installation process. Give yourself an hour and a little bit of space, and your little rascals will be jumping for joy all summer long!

Required skills

Anyone can put up a trampoline – provided the assembly instructions are carefully followed – and you won't need any specialist tools. In fact, trampolines often come supplied with the spanners you need. For models measuring over two metres in diameter, it is advisable to have at least two pairs of hands on deck.The most important requirements are to follow any safety guidelines and make sure you prepare the ground before you start. Your surface must be flat, stable and clear of obstacles.

Installation steps:

1. Checking your equipment

2. Preparing the ground

3. Assembling the frame

4. Fitting the accessories

Tools and equipment


Most trampolines don't require any specialist equipment for installation. The most important part of setting up is to properly prepare the ground. For this step, you will need:

Once the ground has been cleared and prepared, you simply need to use a bit of common sense and follow the installation manual step by step using the spanners provided.

How to install your trampoline

Checking your equipment

Start by unpacking your trampoline kit and checking that all your equipment is present. Next, organise everything you need for assembly. Put the legs to one side and the frame to another. Arrange the jump mat, net and fittings and empty the bags of tools and fixings into a box to avoid losing any parts.

Preparing the ground


It is very important to choose the right location for your trampoline. Firstly, this assures the stability of the structure. Secondly, the right position will secure your installation while guaranteeing a level jumping surface. Use a spirit level to check that the ground surface is perfectly flat. Fill any irregularities with sand to create a level surface.

Some manufacturers recommend digging a trench of measuring around 30 cm in depth to bed down the trampoline legs. This can provide added stability but will require more effort on your behalf! If you plan on leaving your trampoline in the same position, this can be a good option. Whichever way you go, the most important consideration is making sure the surface beneath your trampoline is flat and stable.

Assembling the frame

Assembling the top rail 


The top rail is the part that holds the jump mat in place. It usually consists of several separate tubes which fit together via screws to form a circle.Refer to the installation manual to make sure the parts are assembled correctly. The screws should be well tightened. You should end up with a perfectly circular tube. This is an important step as it will determine the stability of the whole structure.Fitting the feet


Trampoline feet usually come in a U shape. They are made up of one or several parts that connect just like the top rail. Once you have assembled all the feet, simply insert them into the right slots by following the manufacturer's instructions. Screw them tightly and make sure they are securely in place.

Fitting the jump mat


By this point, the frame should be fully assembled. The top rail features pre-drilled holes that are evenly spaced out. These holes are designed to incorporate the springs which hold the jump mat in place. Start by attaching the springs all the way round the top rail making sure they are the right way round (check in the manual if necessary).

Once all the springs are in place, attach the jump mat to opposite ends of the top rail. Proceed to attach the mat on one side then the other, one spring at a time. This will ensure that the canvas is both well-centred on the frame and sufficiently taut.

Attaching the frame pad


You will notice at this point in the installation process that there is a potentially dangerous gap between the top rail and the jump mat around the edge of the trampoline.For user safety, it is recommended to install padding all around the mat to fill in this space and to cover up the springs. This pad simply unfolds around the mat and attaches underneath (check the user manual to see the attaching method).Installing the safety net and poles


User safety on the trampoline is ensured by a safety net enclosure. The net is wrapped around a set of poles that are connected to the trampoline frame. These poles generally come in two parts: top and bottom. Start by attaching the bottom parts to the frame (they usually they screw into the legs). Next, insert the top parts into the net (via the sheaths provided). Then connect the top poles to the corresponding bottom poles, and roll the net down to the jump mat.

High-end trampolines often come with a second top rail to be fitted to the top of the poles. If this is the case for your trampoline, assemble this just like the top rail at the base, and connect it to the poles before rolling down the net.

Fitting your accessories

Assembling the ladder


Assemble the ladder following the instructions in the user manual and position in front of the gap in the safety net. The ladder is an important element as it allows easy access to the trampoline when in position and prevents use when it is removed.

Installing a shoe net


Some models come with a built-in shoe net. It goes without saying that you have to take your shoes off before you get on the trampoline! This handy net attaches to the frame behind the ladder and gives you somewhere to place your shoes to keep them from lying around.
