Healthline: Continuous positive airway pressure (CPAP) pillows are designed to accommodate a CPAP mask. Here are a few options:
Contour Living CPAP Pillow 2.0: Sleeping on your side can be challenging if you’re using a CPAP device and mask. The Contour Living CPAP Pillow 2.0 has center and side cut-outs that help accommodate a side sleeping position when you’re wearing a mask.
You can also adjust the pillow’s height (between 2 and 5.2 inches) and flip it over to reveal a cooling mesh design. Side sleepers report having success with this pillow. They say they rarely have to readjust their mask during the night anymore.
Lunderg CPAP Pillow: Anyone can use the Lunderg CPAP Pillow thanks to its two-side design. However, it’s especially suitable for side sleepers using a CPAP machine for sleep apnea.
Reviewers say the cut-outs accommodate their masks, allowing them to sleep a lot better than before they got the pillow. Side sleepers report not needing to adjust their mask while using the CPAP pillow. A few people do complain that the pillow is too firm for their liking. However, you can adjust the firmness by inserting (or removing) a memory foam layer.
