We got a Dreamcloud
DreamCloud: Luxury Hybrid Mattresses & Premium Bedding and are very satisfied. It comes in a box and you unwrap it and it springs open. We used our old box spring and bed frame. I was skeptical but they give you a year to decide if you like it. Full refund if you don't.
At first we got a Winkbed but returned it, they give you 120 days for a full refund. Found the Dreamcloud for half the price and a year for return. So we figured give it a try if we did not like it go to a mattress store and get one.
