Have you ever wanted your bed to give you a hug?

[This review was collected as part of a promotion.] This bed was put into our guest room and it might be more comfortable than my bed. With the right mattress protector, the mattress is surprisingly cooling and cozy in both hot and cold weather! The mattress has the perfect balance of plushness and support for your body. I would recommend to anyone looking for a new mattress.
