I bought this trampoline at Wal-Mart last year after much debate. Now that it is all said and done I am very pleased with it. My biggest fear was the kids safety, but they were warned ahead of time the first time they got out of hand it was gone! the safety nets works very well. It is 10 feet wide and has padding not only on top of the springs but on the aluminum rails for the safety net. It took us a few hours to assemble, the worst part and the most time consuming was the heavy duty springs. This is a smaller trampoline so no more than two people at a time can be on it, but because we have such a small yard it works out well. They do have larger ones at Wal-Mart for a bit more money, depending on the size of your yard and the amount you want to invest will decide the size trampoline that you will buy.
I am pleased with this in so many ways and honestly I thought it would be a nightmare to have. It motivates the kids to exercise and to be outside in the fresh air instead of playing a video game or playing on the computer and frying their brains. With a little education and rules a trampoline can be beneficial.
