Ordered this while still in the hospital after surgery, because I felt better sitting at a slight angle than lying flat. They arrived soon after I had been discharged, and have worked great for mulitple uses. First of all, my legs needed to be raised to reduce swelling and pain, I had ordered two wedge pillows, and we put them at the end of the bed wedged into each other to make a flat surface, and slept like that for the first couple of weeks. Boy, did that really help my swelling go down! Then I started to sleep with only one at the bottom of the bed angled up from my knee to the foot, still to relieve lingering pain at night, while the other was under my back and head. I love memory foam: I have 3" pad on the bed and contour and regular memory foam pillows, so when I saw these i knew they would be perfect for me, and they have been. Very comfortable to lay on and the slight angle is perfect to promote restful sleep. If you need, or are looking an alternative pillow, just try these, I'm so glad I did.
