When we first opened this up, we thought to ourselves, "this is 500 dollars?" The cushioning on the unit did not meet our expectations, as well as the build quality. The folding spring-mechanism does not work 100% of the time, so it is a bit difficult to get the back rest to go where you want it. Also, the inner springs protrude through the fabric. Would not recommend sleeping on this, even in emergencies. 

Unfortunately, this was not what we were expecting.
