You should check out sinking your trampoline which is inexpensive and far more visually attractive in your garden, quite a few people in the area have used
www.sunkentrampolines.co.uk to do the work - they have done ours and did a fabulous job, and they are the only company to do this. You get rid of the really ugly unsightly netting, and can surround your trampoline with easygrass or rubber matting, or even decking as in our case. Our 2 children (one now 14) STILL continue to use it all the time, and are forever making up new games. It is FAR safer than the alternative, we have never had an accident in 8 years. No brainer, check out their website.
