question:
I've only worn this for a day so far, but I love it! I still have a little bit of a tummy from the birth of my son 8 months ago. This really holds you in, its comfortable and I don't think it shows through your clothes! I highly recommend!!
answer:
Positive

question:
I went through three of these, neither one of them would maintain the air pressure and would slowly deflate. This occurred within 2 uses for each of the 3 mattresses i had. I considered maybe the person sleeping on it was too heavy, but alas, the person is 210 pounds and the weight limit is 300, so that wasnt it. I thought maybe it was punctured, but if it was the person would have awoken on the floor instead of on a supper jeloutnous rubber blob, so that was not it either. What conclusion left is there- this thing sucks and doesnt maintain the air.
answer:
Negative
