This air \"mat\" was something we expected would be like a traditional \"air mattress\" you purchase to sleep on but just longer so we were really surprised when it was finally opened and the air was added. While it does have an air cushion when you are walking on it but it feels and reacts much like a gym mat does or a spring floor in a high end gym. The mat is very heavy - the box was almost for one person to lift - and well constructed. Getting it setup was quick and easy - the included air pump inflated the mat with ease and much faster than expected given the size of this unit. It's been a great hit at our house since it was opened and we look forward to many years of fun to come...
