This Serta Oasis pillow top is the best mattress I have had. It replaced my 20 yr. old Serta and this is so well made. It has cooling gels which keep you cool at night. It has a great lumbar feature for back support. The mattress is a very high quality product. The pillow top is nice and firm and it feels like you are on a cloud. It also has handles that you can move it to the bed without fumbling and dropping it. The delivery service was great. Serta has out done themselves again.
