This specialty pillow improves sleep and CPAP therapy! Wearing a CPAP mask doesn’t have to be uncomfortable. Unlike a regular pillow which fl attens on contact, this pillow’s unique contoured shape supports the spine, neck, head and shoulders while minimizing facial pressure, mask shifting and leaks. It also enhances head, neck and airway alignment for a more restful sleep experience. High-density foam pillow has a form-fitting, removable and washable poly/cotton cover. (20"W x 12" x 3¼")
