We bought our kids a little indoor trampoline a few years ago and recently a few of the springs broke and needed replacing. These were perfect replacements. I just measured the length of my existing ones and ordered the same size. Easy, peasy.I was so relieved when this came and it for perfectly. My little boy uses the trampoline everyday and we were bummed when a spring broke. But honestly it lastly daily jumping for almost 4 years. Jumping makes great quality products.Excelente producto, buena calidad y entrega a tiempo, felicidades !I ordered these because my trampoline came with half the springs missing. These are far superior to the springs provided in the original package, and although they are pricier than many other springs on here, the quality is very obviously superior. Definitely recommend spending the extra money on them. It would have been nice to have that little tool to help install them, but i just used another spring to help pull them into place.Pleasantly surprised on the quality and build of this bench. It is a solid, well built, multi-functional bench that looks like it will last a long time. Full adult size with lots of room for head and legs. I am 6' male and feel very comfortable. Very happy with this purchase.Nearly impossible to put on the trampoline. The tool has not arrived. Should be sold and SHIPPED TOGETHER. The springs seem quite strong and will last a long time- if we can get them ON.One of my original springs broke, and this was a good replacement. However, these springs are not as heavy duty as the originals, so I would not replace all the springs with these. With a set of 5 springs it's a good repair kit. I recommend watching a YouTube video showing how to replace the springs. It definitely made it much easier.I've bought 4 or 5 exercise trampolines over the years. After about a year (+) of ownership the springs would start to break. First, one, then another, until it was no longer safe to use. This time I bought replacement springs and discovered I could easily replace them for a fraction of the cost of a new trampoline.
