Raj, If you are using a CPAP for your sleep apnea, and having any problems with the mask "leaking"........try the "memory foam" pillows. Your head does not sink as far into the pillow...so the mask stays in place better without leakage during the night. (My husband has used a CPAP for more than a dozen years for sleep apnea, and we accidently realized the "memory foam" pillows were beneficial for mask comfort.) * before someone asks......CPAP (constant positive air pressure) basicallly blows air up your nostrils constantly to keep the tissue from collapsing while you sleep...which is all part of the process with folks with sleep apnea.....you wear a mask/headgear connected to the "blower" while you are sleeping.......It works, but it is a bother.
