Like most people I have tried all kinds of pillows to receive my stiff neck--to no avail. I decided to spend the extra money on this (since it was returnable) expecting it not to deliver, but in hopes that it would. I am happy to say the pillow provides great support, yet is fluffy and malleable. It looks a little flat out of the box, but give it an hour or so and it expands to full "fluff". The pillow is very comfortable, provides amazing support despite its soft, fluffy feel. Not being sculpted or rigid foam, it is easy to adjust and get the right support. Somehow it works! I have not had a stiff neck since I bought this. I did add about half the bag of extra material, but removed some because it was a little too much for me. The stuffing is clean, uniform and looks pristine. It comes with a beautiful pillow case that is thick and smooths out any "lumps" (which there aren't anyway because the filling is so soft and uniform.) I plan to order another one for our other home. Highly recommend.

Great quality, not cheap but totally worth this price!

Size: King

I bought this pillow for my husband because the other I’ve purchased have gone flat. So far he is loving this pillow. It has great loft and comes with extra to adjust if necessary. I’m going to purchase one for myself as well! It is extremely comfortable!

You have to reposition to stay cool

Size: Queen

It's okay...it isn't much better than other cooling pillows I have had. If I had known you can't wash this pillow, only the outside cover, I would not have paid so much. The cover is cool to touch but the heat from your head will penetrate the pillow and I am constantly having to turn it over. So it is ok but way overpriced.

I like my Sujo FlexCool pillow

Size: Queen

It cools nicely and it is possible to add or remove fill to optimize preferred comfort. Quality made and very comfortable for me after I added some of the fill provided with the pillow.

This was not for me

Size: King

Hmm… I didn’t hate this pillow but I was not blown away either. I’ve been using Sleep Number pillow, and since the price range was similar, I thought this might be a great alternative, especially when it’s hot. Even though I was able to adjust the filling, I couldn’t find the right shape/density. And I found that this pillow felt hotter when I was sleeping. After trying it for a few weeks, I went back to my Sleep Number pillow. The quality was fine. But I guess everyone is different, just like some people prefer a softer mattress and others don't.
