This is a very firm mattress which is what I like.  You can not tell when someone is rolling over on it when you are sleeping.  It also makes my bed taller.  I love the navy color of the mattress.  It was delivered on time and the guys put it on my bed for me and took away the packing which was really nice. The stitching is perfect with all the edges caught and the finishing edge is all covered.  The mattress has a cool feel to it just lying on it but I do have a waterproof mattress pad on it which I do not feel as much with that but want it to be protected.  I would purchase this mattress again without any problem.  Thank you Serta
