I had a 20 year old Tempur pillow that was past its best. The Panda pillow isn't contoured, but I've found it comfortable for both sleeping on my back and on my side. I haven't had any discomfort or neck stiffness whilst using the Panda pillow (I was starting to suffer a little of that with the old pillow) so based on three weeks of using the new pillow I'm happy with it and have no wish to change it.
