It is not difficult to find a memory foam mattress topper to suit your personal needs. There are various options to choose from and these mattresses come in several price ranges. The memory foam mattress topper may not be an ideal substitute for full sized memory foam mattresses. However they can offer maximum support and comfort to your old mattress. Hence if you do not wish to change your entire mattress you can just spend a little on your mattress topper.
You can shop for memory foam toppers in varying thicknesses that range from 4 inches to 2 inches. You can choose from lighter or heavier varieties as well. You can get one that is at least 3 inches thick if you wish to buy something with a softer feel. However the 3 inch and other varieties may be costly. Hence the best way to use an old bed which you do not wish to dispose off is by using a memory foam mattress topper on the same bed.
