For those who require the ultimate in pillow comfort, this pillow is sculpted to support your head and neck, take stress off of your muscles and keep your spine aligned. Memory foam pillows maintain their shape for their lifetime, and while comfortable and soft they are also dense enough to offer unparalleled support. Memory foam reacts to body heat, moulding itself to your head and neck and offering perfect support. These pillows are also non allergenic and a very poor environment for dust mites, so those sensitive to bacteria and other microbes can rest easy. The cotton-rich velour cover is easily removed for washing, and adds one final layer of luxurious comfort.
