Side sleepers require a pillow that provides enough support to keep the head in alignment with the shoulders. If a pillow is too soft or lacking enough support, it will not provide enough lift to keep the head from sagging.
Back sleepers require a pillow that will provide enough support for the neck, while allowing the head to settle into the pillow.
Stomach sleepers require a pillow that is very shallow and flat or very soft and conforming. Memory foam pillows are often too firm for stomach sleepers.
Mattress protectors are an integral part of quality sleep. Mattress protectors help keep a clean, hygienic sleep surface while protecting your mattress from dust, dead skin and persipiration.
