Jumping Bed
Polymesh is generally found on round trampolines. It should be manufactured from Grade A non-abrasive, Permatron polypropylene. This does not provide any additional elasticity, but the tight 'weave' does provide a smooth surface which does not graze children's skin.The 2-string bed is made of nylon, and is found more typically on rectangular trampolines. The wider weave allows good air flow giving a higher bounce, and will dry quicker after rain. However it does have a rougher surface and may cause grazes to elbows and knees i.e. 'trampoline mat burn'. Trampolines with a 2-string bed are better suited for adult use or gymnasts who are used to performing more advanced trampoline moves.
The bed should be attached to the springs by galvanised steel triangular rings or injection mouldings (UV stable) The perimeter stitching should be in UV stable thread, and in multiple rows for extra strength.
