Input: I've owned 2 beds for over 2 years now and both beds have held up extremely well considering the amount of constant use they've had. One of beds I actually sleep on daily (more comfortable than my regular bed). I had it over 2 years before one of the inner baffels gave way a few weeks ago. I immediatly ordered another bed without hesitation. Very comfortable and super easy to use, with the built in pump, it's a snap to set up and deflate. Love this bed!!
Output:
Positive
