I was skeptical in ordering something that I had not tried, but decided to trust the majority of reviews I read. .The Hudson SleePAP pillow does all that it is supposed to do .... it allows me to sleep. I recently was required to use CPAP therapy. None of the pillows I tried worked as they all allowed the mask or nasal piece to rub my cheek or nose area, waking me up throughout the night. The SleePAP pillow has cut outs and soft areas that allow the mask or nosegear to "fit in" the space and not rub against the face, when I sleep on either side or on the stomach. It also provides for comfort and neck support for me when laying on the back. It comes with 1 pillow case. I will be ordering a 2nd pillow as a backup/spare or travel pillow.
