I have been using my new pillow for 3 weeks and it is comfortable and supports well in any position I sleep. I start the night on my side but change to both stomach and back during the night. I gave the second pillow to a friend who has severe arthritis. She is a side sleeper and has much difficulty getting comfortable. Since using this pillow she is able to sleep uninterrupted for 4 hours which is a record for her. I highly recommend these pillows.
