We bought this for our camper and could not be happier with it. We actually slept on it maybe 6 hrs after opening.  I was nervous ordering it online and not being able to try it first,  but after 1 night my husband said "nice work".  We bought the 12" as we are both side sleepers.   I weigh probably 140 and my husband weighs around 220.  Wished we had found it sooner as the old bed was definitely shot.
