I bought this for my "just-turned" four-year-old son who, like most boys, loves to jump on the sofa, the bed and anything that looks a little bouncy.
It was easy to set up (it says you need three adults but my husband and I did it easily). It appears well crafted and durable -- time will tell.
The directions say that it is good for up to 200 lbs.
My 37 lb son had a lot of fun jumping right away, although he did not jump as high as one thinks of with a trampoline. But for a small, indoor trampoline, I don't think you want your children flying too high. I also think that as his weight and ability increase, he will get more bounce out of it.
My biggest reasons for buying it are the safety (no springs, padded edge) and the size. I can easily remove the feet and slip it under a bed.
On a really hot day, we can still burn off extra energy inside.
We put a chair at the edge (turned around) and he then had a handle to hold while jumping.
Safety is a big factor with any toy that increases the movement of your child so we went over all the safety rules before he took one step on. I think that any toy is as safe as its surroundings, supervision and appropriate use.
We also have the Jump-o-lene (an inflatable jumping toy). Although we enjoy that as well, it takes up a lot of room and requires a lot of push to gain any bounce. I am hoping this is the next step up in strengthening leg muscles and increasing one, and two footed coordination. 4 stars

I use this minitrampoline for cardio exercise (jogging in place) when the outside temperature, or my knees, tell me not to run.

This is my second mini-trampoline. The first one used springs instead of the elastic bands. The spring design sucked. I trained for a marathon and put many hours on it. I decided it was unsafe to use after the 4th spring broke (from fatigue or friction - probably a combination of both). I bought replacement springs and discovered one needs a special tool or superhuman strength to put them on.

That's when I discovered the design was changed to incorporate bands, replacing the springs. Much better. I happily purchased the newly designed unit for which this review is written. I have put many many hours on this new "band" unit and so far no problems. 5 stars

The instructions for this product actually call for THREE people to put it together. My boyfriend and I managed to do it with two, after about 45 minutes and a great fear of losing our eyes. If you do buy this (which I do not recommend), put it together on a carpeted area, that seemed to help us. I will NEVER take it apart for storage - first, because I'm scared, and second, because it will take days to put it back together. Also, at one of the places where it had been welded, it is rusting AND one of the legs was too big to screw onto it's peg. Oh - and there is an unadvertised weight limit of 200lbs - so you can only use this if you just sort of need it, not if you really need it. 1 star

If you want a mini-trampoline, I can recommend this one. It is built like a battleship, but assembly is non-trivial -- you need at least two adults (the instructions recommend three) to fight against the tension to pop everything in place. No big deal, but you are not going to put this together by yourself -- you can hurt yourself if something pops back due to the high tensions involved. The instruction book could use larger and clearer pictures. The legs screw on, and one of the legs in mine was slightly out-of-round, making for some stiff turning, but I got it on. There is an 800 number to call the manufacturer for any problems. I didn't need to call. We like this mini-trampoline. 4 stars

Perhaps I got a defective product but I ended up in the emergency room trying to set up this trampoline. We followed instructions and were very careful but after putting the main pieces together and wrestling the two sides down flat - it sprang up and hit me in the face with a lot of force causing a laceration on my face and a lot of bruising. The instructions do not indicate that this is a possibility. No product this dangerous should require assembly. Be Careful. 1 star
