This is the pillow that optimizes CPAP mask efficiency while increasing the comfort of its wearer. Unlike typical pillows that interfere with mask performance by breaking a cushion's seal, this pillow's hose-friendly, twin cutaways prevent a mask from leaking while its cool breathable mesh, perforated memory foam maximizes comfort and limits perspiration, ideal for use with humidified air. The cutaways combine with an integrated fabric tether to keep hoses from crimping or snagging, enabling left- or right-side sleeping without re-adjustment. The pillow's thickness varies using a removable 3/4"-thick foam insert while its ergonomic shape conforms to the natural curvature of the neck and shoulders for comfortable side or back sleeping. Works with all mask types. Includes an extra washable pillowcase. 20" W x 4 1/2" H x 13" D. (3 oz.)
