We have the Galt Nursery Folding Trampoline (www.educationalgalttoys.com) and the kids love it. It's not bad to assemble. Our 5 and 3 year old love it. We love it in the winter and rainy days when the kids can't run outside as much! It's good for kids up to 75 pounds, or two little kids totaling 75 pounds.
Have fun!
