My 2 yr old daughter LOVES this trampoline, and I love it because it tires her out! I put it together on my own, it would have been easier with two people, but it is doable.  I found the directions pretty simple to follow.  I used a drill instead of the tiny screwdriver that comes with it and it went much faster.  The only reason I'm giving it 4 out of five and not give is because I doubt she will be able to use this up to 7 years of age.  She fits well now ( she's a small 2 yr old) but she doesn't seem like there's much room for growth.
