Developed by NASA (National Aeronautics and Space Administration), memory foam was first used to alleviate the pressure on astronauts' bodies during lift-offs. Memory foam later entered the public sector as a recovery aid for victims of bedsores. Memory foam cradles the body instead of working against it. Memory foam mattress
toppers are made of visco-elastic foam cells, which are pressure and temperature sensitive, capable of relieving pressure on the body’s joints when used for sleeping or sitting. Despite its resiliency, memory foam requires special care.
Rotate the memory foam mattress
topper every two to three months so that the area that was at the foot is now at the pillow end. The rotation prevents permanent body impressions in the memory foam.
Protect the memory foam with a mattress pad. A cotton, stain proof mattress pad will keep the mattress topper clean without interfering with the feel of the memory foam. Remove the mattress cover monthly and throw it in the washer, replacing it once it is clean and dry.
Spot clean the memory foam mattress
topper. Dampen a sponge with water and gently clean the affected area, rubbing in a circular motion. For tougher cleanings, add a squirt of dish soap to the sponge. Rinse the area with a damp cloth and allow the mattress topper to air dry.
Hang the memory foam mattress topper out on the clothesline on sunny days. Drape the mattress topper over the clothesline or over a chair to air it out and eliminate odors.
