Everything about this mattress is great except for the height and weight. It is by far the most comfortable mattress I have ever slept on. We have been sleeping on it for about 3 years and can't imagine switching to anything else. It is neither hard nor soft but is fairly firm. And I do not find it hard to turn over during the night at all. However, it is very thick and even though I am 5'7" I have to climb up on the side rail to get into bed. And it is impossible to rotate the king size, which weighs 185 lbs., and is even kind if difficult to change as it's very hard to tuck the sheets and blankets under the mattress since it is so heavy. Even with these problems though I love this mattress because of the wonderful night's sleep it provides.
