Overall excellent comfort and support. We have tested and owned several other mattresses and have found this one to be the best.
We have been battling the past year to replace our queen mattress with a king mattress that is comfortable for both of us and similar to our queen mattress (no longer made but consisted of a latex, memory foam, and support foam layers). We have tried 4 different brands of mattresses and have found this to be the most comfortable and is similar to our queen mattress. What we have discovered over the last year is that mattresses made with only memory foam and support foam, and can't be picked up easily by one person (mainly because they are extremely heavy) are not comfortable. They are too firm and have no give or bounce to them. The Caledonian Foam mattress is easy to lift, and it is not overly firm, but no overly soft. As a result it provides a very good balance of comfort and support. In addition, it does not seem to sleep cool or hot, unlike our pillow top experience which was too hot, and the memory foam which was too cool. The temperature is just right. The cover to bed is removable and washable. Overall. we are very happy with sleeping in this bed and are sleeping through the night comfortably. We have decided to give this a good 30-60 days before deciding to make this a permanent part of our lives. Our preference is to have a king size versus queen. If all goes well we may consider purchasing a king size in this mattress. I will provide updates as necessary to this review.
