ObusForme Airfoam Support Pillow – 4-Position Memory Foam Lumbar Support Pillow, Portable Posture Support, Machine Washable Plush Cover

Yep! I got it by searching for CPAP pillows, since I was trying to use the mask while sleeping on my side. It became unavailable and I wouldn't hold my breath as Amazon actually sent me information about a scam. (I had purchased a backup, and both orders of mine did appear and I told Amazon that but it got discontinued soon after 😅) I sleep on my side at night and the pillow is not tall enough and I just put a folded blanket underneath it, and then in the morning when I've tossed and turned and rolled onto my back, the dip in the middle means that my neck isn't hurting as much! For me being in so much pain all the time, a pillow that can accommodate that for me is huge. I do lay on my back during the day with this one but for the tossing and turning the CPAP pillow is so great due to the different regions. There are other similar pillows on Amazon .ca and. com and if you do a reverse image search it might help. 🙂
