Performance & quality

alt text DualTek double strength frame Made from 2mm thick galvanised steel our frame is extremely strong and designed to be under the ground for many years.
alt text Built in retaining wall Our purpose designed kit comes with a 4mm thick recycled plastic wall, which can be attached to the frame easily using the pre-drilled holes and the screws provided.
alt text TDU Vented Safety Pads The patented Trampolines Down Under vented safety pad allows proper airflow through the pad eliminating 'pad slap' noise, which can occur with other in-ground trampolines, and greatly improves the bounce quality.
alt text Commercial Grade Springs A quality spring will give a better bounce – and last longer! We have been in the business of trampolines for 17 years – we have selected a high quality 8.5” commercial grade spring for our in-ground trampolines which are double-dip galvanised to protect against rusting and stretching of the springs.
alt text Professional jump mat + spring guard There is an extra piece of material sewn onto the outside of the jump mat to provide additional coverage of the springs, this is called a spring guard.
alt text Made in the EU The quality of our in-ground trampolines is of the upmost importance to us. We have carefully selected the highest quality component parts and materials. Our European manufacturing process includes an extremely high level of quality control and product testing.

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.

The measurement stated on our website calculates the full size of the trampoline, the springs/padding round the outside take up around 1ft. So on a 14ft x 10ft In-ground Trampoline the jump space would be approximately 12ft x 8ft and on a 14ft you'd get around 12ft ft of jump space.

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 delivery take?

All our in-ground trampolines are send free on a next working day delivery service. 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.
