We bought this to replace a cheap, thin mattress in our camper.  We've slept on it three times so far.  It serves the purpose but is a bit too firm for us.  I tossed and turned a bit and we woke up a bit stiff in the morning.  But, to put it in perspective, we have an iComfort mattress at home which has spoiled us.   For our intended purpose, it works just fine.
