I have a gel top mattress topper and there is no question that gel is through out the topper, I was under the impression that these "gel-filled" pillows would almost feel the same as my gel filled topper. It didn't. It's just a more denser down alternative pillow. Can't tell that there is supposed to be a gel like substance in the pillow to help with the support I was looking for, which is also pretty crappy. I would have returned these but I hate dealing with returns and the cost of shipping the item back. These are now just expensive decorative guest pillows.
