True to its' name Serta Perfect Sleeper Firm Mattress. you won't regret buying this. With my old mattress which I paid almost double the price of this Perfect Sleeper I always wake with a back pain and shoulder discomfort and through out the night I keep on tossing on the left and right side just to get a better feel of body support . After using this for a week I really experience a night of restful sleep and I don't have anymore back and shoulder pain discomfort when waking up in the morning. it's really a firm mattress that really gives you comfort and support for your body. What more can you ask besides for a good price value, Serta is standing by their product by giving us the consumers a 10 year product warranty. That's peace of mind and a restful sleep for me.
