Our mattress topper to help you improve the mattress in your bedroom. If you feel the mattress you purchased before is firmer than you thought and it takes a lot to change or return, you could consider this kind of mattress top. It consists of memory foam and fiber to make the firm mattress softer a little. It is only 1.57 inches so it would not make it too soft and would not add the height of the mattress to change the outlook.
