Get positioned for better sleep! The shoulder curves encourage proper positioning to give you night-long comfort. The design of the PAPillow™ allows you to “sleep on the edge.” At five inches, the side panel has a clean edge that will maintain the nasal or interface seal without interfering with ventilation. The double edge means as you turn during the night, you’ll still get have the edge you need. What’s more, it allows you to do it without the need for a second pillow, even if you’re a side-sleeper. Includes a washable, 100% cotton jersey knit pillowcase.
