We ordered the king! Arrived quickly, packaged well, instructions were stuck on the inside of the box - almost missed it. We left it out to “breathe” for about 48 hours. It made out bed shorter which is welcomed. It is quite firm (have slept on it for a week). Good for side and stomach sleepers - will take some breaking it in to make it easier on side sleepers (which i am mostly). Overall, happy with it!
