I purchased this to go in the forward berth in my sailboat. I was a little skeptical about the memory foam as I have slept on a MF mattress in a hotel and was not impressed. The shipment came fast, 3-4 days. I ended up only using the firm foam and the MF layers, I tried all 3 and then just the 2 and couldn't tell a big difference so I opted for the lower height which gives me a little more head room on the boat. I've slept aboard a few nights now and love it. I'm not a good sleeper and toss and turn a lot. It drives my wife crazy. As soon as it warms up and she tests out the new mattress on the boat, I bet we'll be buying one for the house too. I would buy this again. I looked at something similar at IKEA but for 1/4 the cost the Overstock option was the best buy.
