The trampoline came disassembled but then instructions are very easy to read and the trampoline itself was simple to put together. My 14yr old daughter did it within 20 mins. I think if I did it, it would've been faster. The base is very sturdy, I love that the bar to hold on to has a padding incase they bump into it and the padding around the trampoline is thicker. The colors are bright and fun. My son has not stopped jumping on it. It's a great way to tire the kids out too. I am very pleased with the quality of the trampoline and I recommend it to other moms with small children. I will say that it holds about 40 -50 lbs.
