Roho Sleepmatterzzz Ultra Memory Foam Cervical Pillow - Standard Size, Dual Valve

I have back & neck problems and this is the best pillow I have ever tried (and I have tried many). It is better than an all-memoryfoam pillow because all types of foam eventually get compressed. This pillow is filled with air and I can adjust the air to exactly the best height for me. I have had one for 4-5 years and it is just now beginning to show age signs, but I still use it under my knees. This new one is better than the first because it has two air chambers. It adjusts easily and rarely needs to have air added. I tried a water-filled pillow once and it worked fairly well, but it was so heavy that I could barely lift it! The Sleepmatterzzz Ultra pillow is great for my neck and whole back (if my neck gets out of whack, then my whole spine gets out of alignment and my whole back ends up in pain too). I was afraid to try the less expensive version -which does not have memory foam surrounding it -because the other one had worked so extremely well for me. This is the BEST pillow I have every had.
