I've been looking a long time for a mattress that is both comfortable and supportive to my back. I am so excited to have found this mattress, because it hits every box of what I was looking for. My husband and I have had back and joint problems for as long as I can remember, and this has already helped to lessen the pain. I feel like my body molds to the mattress, but it doesn't feel like I'm sinking into it. It's very supportive but still soft. The quality is phenomenal, and I'm very pleased with how durable it feels. All of the seams are sewn well, and it's maintaining its shape with daily use. A huge feature is that it's cooling, and I don't wake up sweaty like I used to. Even when I'm just watching tv in bed I don't get as warm. It also has motion isolation so my husband and I don't feel when each other is moving or rolling over. This is a very high quality mattress, and it's shown by the quality of sleep it provides.
