The Boomer is an Olympic size, heavyweight outdoor trampoline made from ultra-thick hot-dip galvanised UK steel. It measures a whopping 5.16m x 3.0m (16'11" x 9'10") giving you huge amounts of space to perform aerial tricks and manoeuvres. 

The frame weighs a hefty 246 kilos, whilst the steel is tensioned to increase the strength of the frame, eradicating any possible flexion of the steel. This is achieved by designing the steel side rails and leg bases to work in unison to push the side rails outwards, thus increasing the tension dispersed through the springs and 2-string bed.

Unlike other brands, we do not punch holes in the steel frame to fit springs in to because this weakens the steel. Instead, we have designed our own spring anchor straps which wrap around the frame, giving the spring fantastic mobility and zero friction with no metal-to-metal contact.  

The frame is flat-pack designed meaning that building the trampoline is a family-friendly activity and does not require a professional – although we do offer a build service for those who would rather not do this themselves.


So, what is a 2-string bed? And what makes it so special?

Well, the 2-string bed is a high-performance jump surface weaved from string in a 2x2 formation. The small gaps between the strings created by the weaving process means there is little air resistance from the fabric, and thus, increased bounce potential. The 2-string bed is not a common site on outdoor trampolines, featured only on our Super Kangaroo and Boomer trampolines. This bed style is arguably the strongest available, whilst offering unrivalled durability and requiring very little maintenance. The strings are protected by a UV-stable protective coating meaning it can prosper outdoors all-year round whilst providing grip and stability to users. Our 2-string beds come in black with white markings as standard, but can be customised to come in yellow with red markings, or white with black or red markings. 


The protective frame pads that cover the springs are made from a UV-stable high-grade PVC available in garden green as standard, or can be customised to come in blue, red or orange. Other colours can be sourced at additional cost so please get in touch if you have another colour in mind. Logo application to your frame pad can also be achieved (surcharges apply). 

An elevator kit is also incorporated into the design of the Boomer. This inventive piece of kit attaches to the frame and sits between the underside of the pad and above the springs. Its main functions are to prevent the 'pad slap' sound you sometimes get when bouncing, and also to protect the corner pockets of the frame pads to prevent your feet sinking through the pad if stepped or landed on.

    Super Tramp Boomer

    Posted by Alison on 16th Aug 2021

    This trampoline is amazing. My son got to be British disabilities champion using this as his main training trampoline. They last brilliamtly and is still just as good 8 years later. We got it second hand and it was years old then.
