hi cathy
i bought this one for my girls for christmas:

they love it and so do kids who come to visit. i prefered the design as it's harder to tip over than this one:

if your kid gets really into jumping, this one looks like it'll tip over. i've seen a kid going at it and the back two legs coming off the floor a little.
the only downside to the first one is that there is an 80 pound limit. sometimes i want to get on there too :) oh and it has music. if that's going to bother you, just don't put in the batteries. and you'll need 2 people put it together.
