I purchased this tumbling mat for my 5, 6 and 8 year old. They are having so much fun with it! It is easy to set up and blows up in minutes. The mat is very sturdy and high quality. It gives just the right amount of bounce for my girls's gymnastics. It is long and plenty wide. It takes up my entire living room, so this will definitely be used outside. It can be used for lots of things including exercising for Mom! It is a bit pricey, but definately worth it for the quality. It is a bit heavy and bulky as it should be for the size and quality of this mat.
