Comfortable and washable

Five stars. I use a pair of these on an IKEA Trundle Bed. They are 100% nicer than the equivalent IKEAs at the same price point. When you get them, they off gas a little bit, but leaving them for 48 hours fixes everything. The dimensions seem true, the pair is about 10 inches thick. You can leave them stacked for a twin sleeper, or separate into two mattresses to make the equivalent of a king. My only complaint is that when you first lie down on them, it sounds like you're crushing Saran Wrap. It's not irritating enough for me to do anything, it just sounds like soda fizzing. Goes away in about 15 seconds. Excellent value and very comfortable--Way more comfortable than the firm IKEA foam.
One very nice feature-- the cover is completely removable. I used a bed bug encasement cover on the inner foam, and then put on the factory cover to compress it so that there's no excess. The factory cover is cotton and unzips easily breaking into two pieces. Easy to wash.
