This has held  up well for a year of use.  Still a good rebounder.  And quite sturdy as well.  My kids used it to crawl in a window to get in a locked house one day very recently...after we've had this for a year now in the backyard - never been brought in....and my kids are no longer small (100 lbs and 150 lbs) and they were both on it.  I didn't realize they used it till later and was surprised the thing is just as good as new.  I'm not advocating it for this use (Yes, they were scolded for using it in this manner) but just to show that it is a good, sturdy product.
