The Memory foam cover does, literally what the name suggests and it covers the memory foam mattress. The cover, apart from serving as a soft interface between the memory foam and the body, also performs several functions such as protecting the mattress from accidental spills, urine stains, tears or wears and aiding in aeration to dissipate body heat buildup as well as absorb moisture.
It is very important that memory foam covers are replaced when they are worn out as an old memory foam cover will not be able to perform its protective and other essential functions. Therefore knowing when its time to throw out the old cover is important. Here are some certain signs that should let you know when to get a new replacement.
Sagging or flaccid memory foam covers:
Memory foam cover takes the full brunt of the hard body contours and provides a protective cushioning to the mattress underneath therefore it gets damaged first. Remove your memory foam cover and check for sagging areas, if it has become prominent it should be replaced.
Repeated washing due to staining:
Memory foam covers are washable but repeated exposure to water or moisture greatly reduces its life span. Therefore if you have washed it a considerable amount of time. After washing, drying and sleeping over it for a night always check to see for appearance of any signs given above.
Heat build up:
If you do notice that your memory foam bed seems to be hotter than usual it is probably because the memory foam cover is worn out and is unable to carry out aeration to eliminate heat build up. Just make sure it is not because of the temperature though.
Tears or breaks in the cover:
If your memory foam cover is torn at places it is recommended to have them replaced. Note that this is not because it will reduce its functionality by any discernable degree but more so because it will lose its ability to resist water (in case it is water proof) and will also be no longer dust mite proof.
With memory foam covers taking the major brunt of wearing effects and facing the elements, they tend to wear out relatively fast. Therefore it is essential to get good quality covers.
