Life Expectancy of Memory Foam Mattress

Memory foam mattresses are popular with consumers because they contain a viscoelastic material that comfortably cushions the body and promotes a feeling of weightlessness. The lifespan of a memory foam mattresses will depend on the density and thickness of the memory foam. A mattress that has only a small quantity of viscoelastic material won't last as long as one containing high-density memory foam.

Quality

A memory foam mattress consists of high-density viscoelastic attached to a polyurethane base. Lower density mattresses will sag and lose their shape more quickly. Look for a mattress with a 3- to 4-inch depth of memory foam and a density of between 36.3 and 64.9kg. Ensure that the material covering the mattress is of good quality and well stitched.

Considerations

Keeping an electric blanket on while sleeping can damage the cells in memory foam, giving the mattress a shorter lifespan. People who are overweight may also find that the mattress will sag and lose its support more quickly. Placing the mattress on a firm base will make it last longer. The mattress will contour to any defect in your existing base, so ensure your bed base has no dips in it.

Misconceptions

Some people mistakenly believe that a memory foam mattress topper will have the same lifespan as a mattress. Toppers are generally thinner than mattresses, and those only 1 to 2 inches thick will wear out quicker because the cells at the top crumble and there isn't enough memory foam underneath to take their place and support the body. A quality memory foam topper will last up to three years if it is made of high density foam, is reasonably thick, and the underlying mattress is in good condition.

Care

Use good quality bed coverings to keep the mattress in pristine condition and preserve its lifespan. Remove stains by dampening with plain water and sprinkling with dry boric acid, usually found in the laundry aisle of the grocery store. Blot with a sponge or cloth in a circular motion. Blot dry and vacuum with a hand vac or soft brush attachment to remove residue.

Tips

Look for a memory foam mattress with a minimum 10-year guarantee. Check that the mattress is well stitched and has a quality protective covering. Take your time trying out the bed, and consider one that comes with a 30- to 60-day refund option.
