I waited a long time to review this to see how it held up. I bought this in February and it's now November and the top "egg crate" type memory foam is falling apart. The thick under foam is not very comfortable by itself and doesn't appear to be memory foam, just regular foam. We've gone through quite a few mattresses, the most recent being a rather expensive pillow top mattress that is over 16 inches deep- the pillow top sunk after about a year and as with most mattresses I've tried, it started dipping toward my husband's side (I'm petite and he's over 6 ft and around 250lbs) so it was flat and pulling me into a twisted position - we bought this in an attempt to save it - it was too soft for about the first week or so and afterwards was comfortable for a few months, we rotate it regularly to try to keep the foam fluffy, but the egg crate portion has become smashed and is cracking and coming apart, the thicker foam piece is still fine it just does nothing for the bed. This would probably be great for a guest room or to throw on top of a pull out couch for company, anything that doesn't get used on a regular basis. But for daily use, it just isn't worth it.
