What size trampoline should I choose?

A bigger trampoline is always more fun! However, we understand not everyone has the space. We'd always recommend going as large as you can afford - kids only get bigger and these trampolines are designed to last a whole childhood.

Round or rectangle?

This is really a case of personal taste and the design or shape of your backyard. However, rectangular trampolines are great for kids into gymnastics as there is a nice even bounce across the whole trampoline. Round trampolines we think always have the ultimate bounce, but that is mainly in the centre of the trampoline.

How long will it take to install?

Our trampolines have been designed to install yourself, how long it takes depends on the size of trampoline you choose and whether you dig by hand or hire an excavator. Digging by hand we'd say allow a weekend to complete the job, if you hire an excavator you'll easily do it in a day.

Do I need to build a retaining wall?

No! Our in-ground trampoline kit has a retaining wall built in, making it even easier to install at home. The retaining wall easily screws onto the frame into pre-drilled holes.

Do I need to hire an excavator?

This depends on the size of trampoline you choose and how energetic you're feeling! We'd recommend digging the 8ft and 10ft sizes by hand as it's actually easier to get the bowl shape you need with a spade than an excavator. But for the largest sizes hiring an excavator will definitely make less work for you.

How much soil do I need to excavate and how do I dispose of it?

The amount of soil you need to excavate will vary depending on which size trampoline you are installing. For the smaller size trampolines you will fill a 6-yard skip (10ft x 6ft, 8ft) for the medium size trampolines you will fill an 8-yard skip (10ft and 11ft x 8ft) and for the larger trampolines (12ft, 14ft & 14 x 10ft) you may need to arrange for a grab lorry to come and collect the soil. If you are able to use the soil in your garden for raised beds or levelling ground etc. then you will save the cost of a skip or grab lorry!

Will I need to add drainage beneath the trampoline?

In most cases, a simple soak away as described in the instructions should be sufficient to ensure your trampoline pit drains well. For some gardens that have a high density of clay you may need to consider alternative drainage options such as the ones outlined in our blog.

How much room should I leave around my trampoline?

If you do not have a net on your trampoline then you should leave at least 1.5m around the perimeter of the trampoline to avoid the user bouncing off the trampoline into a potential hazard such as a tree or fence. You should also make sure that there are no hard surfaces within this area such as a stone pathway.

How long does shipping take?

Shipping takes between 5-10 working days, you'll be provided with a tracking link once your order has been dispatched.

How do I look after my Capital In-ground Trampoline?

Fortunately, the Capital In-ground Trampolines are relatively maintenance free! It always helps to prolong the life of your trampoline pads and jump mat if you purchase a cover. Likewise keeping your trampoline clean of general garden debris such as fallen leaves, twigs and mud will help maintain all elements of the trampoline. We recommend that you check all parts regularly and replace any worn out parts as soon as you notice them.
