My wife and I were excited to try an zen mattress, and to get a brand new mattress finally! We both thought we enjoyed firm mattresses, and we're both fairly small, but we went out on a limb and got a Kingsize. The mattress is soft and the memory foam is luxurious. My back felt immediately relaxed the first time we got on it. Though this is softer than any mattress we would dream of having, it is super supportive and doesn't seem over-soft the way “luxury" mattresses can. It's like zen knew us better than we knew ourselves. We are very very happy with it! We look forward to sleeping on it every night.
