A tighter or higher thread count fabric has more durability than a lower count. Waterproof pads are made in a conventional manner, but with a vinyl barrier on the underside that prevents any moisture from leaking through to the mattress. Eggcrate foam pads are made of a soft foam that provides therapeutic benefits. Some of these benefits include increased circulation, relief of back pain, and a more comfortable, restful sleep. Since wool breathes, these pads keep you warm in the winter and cool in the summer.
All mattress pads are machine washable and dryable, except for heating, foam, and some wool pads.
A simple form of care is always described in your care instructions label, and should be followed to maintain and maximize the life of your mattress pad. Handle heavy, wet mattress pads carefully when removing from washer to dryer. Make sure to replace your mattress pad when it shows signs of wear or no longer provides support. Foam pads should be hand washed in a large basin in mild detergent. Do not wring or twist pads as they will lose shape, and do not machine dry, as high heat will cause the foam to become hard and disintegrate.
