I have used the standard-sized bodipedic pillows for years and love them. I was excited to order these for my new king-sized bed. I didn't order one, I ordered four (assuming they were the same). They're not. These don't feel as heavy and dense. When I first opened the package I was totally disappointed, based on feel alone but I have sleep on them for a week now and they sleep really well. I actually think I like them better. Don't buy them expecting them to be like other bodipedic products. Buy them without preconceived notions and I think you will be okay. I truly like the pillows, they are just different.
