UPDATE 11-12: The trampoline still has a solid base and solid legs. We take it out periodically and jump away. The blue outer vinyl band looks a little worse each time but it is almost 10 years old. The fact that the basic trampoline structure is as solid and sturdy as the first time we used it is a testament to the durability.

UPDATE 9-09: My son is now 10 and I have a 5 yr-old daughter. This trampoline has lasted through tons of use. We continue to find fun things to do with it. We have used it on the end of a dock to jump into water. It has been part of 'obstacle' courses. It is great for exercise and balance. The only thing that has given a little is the blue outer ring. Not a big issue but with multiple children using it for over 6 years, there are some tears to the vinyl. Nothing a little duct tape won't fix! The trampoline base has no signs or wear or deterioration and the legs are solid and straight.

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.
