Our 25 year old son with autism LOVES trampolines... we've had one for over 20 years. Zupapa is far superior in quality and customer service!!! All three times we've had structural issues (our son jumps hard and for hours) they have happily sent free replacement parts. Elaine assisted me most recently by sending some needed springs, again free of charge. I'll never buy another brand again. Thanks Zupapa!!!
