Try a different pillow
Size: Upgrade Queen (2 Pack)
Even with all the memory foam in it, it's still flat. No firmness to it. I hoped it would expand and settle in the few weeks I've had the pillows, but nothing works (dryer, fluffing, etc)

This is a must have!
Size: Upgrade Queen (2 Pack)
One of my favorite purchases! I love that you can take stuffing out as needed. My husband kept majority of his in because he likes a full pillow. I prefer a flatter, soft pillow so I took out probably half of the stuffing. We both love them!

Excellent pillow.
Size: Upgrade Queen (2 Pack)
Wow these pillows are fantastic!!! First off they are good quality and sized as described. I'm forced to sleep on my back since I use a cpap every night. They suggest taking some filling out for "back sleepers". But in my case, I am disabled, overweight, and the way I position myself on a pillow is probably unique. I have a little of my shoulders, head and neck on the pillow. I didn't have to remove any filling. It was pretty good at first and after about a few day/nights, everything settled in just perfectly. It's truly one the finest pillows I've owned to date. (Part of my disability is a very painful neck & muscle malady, my head leans far to the right. Basically feels like a crick in your neck that never goes away. It's called tortacollis or dystonia depending who you talk to.) Because of this, I have truly spent hundreds and hundreds of dollars on different types and styles of pillows. A very select few have worked out fairly well over time until I found this one. As I said in the beginning, this is an excellent pillow and a great value as well. Hopefully this will work as well or even better for others. I purchased a 2 pack this time, 1 for home and the other for our RV. Definitely buying. another 2 pack to keep for future replacements. Pillows simply don't last forever. They get funky in time. No matter how clean you try to stay with bedding and personal hygiene, it just happens eventually. Sweet dreams. :~)

Size: Upgrade Queen (2 Pack)
Incredibly thick and firm pillows. Not great for stomach or side sleepers. They alway end up on the floor cause we find them uncomfortable. Don’t recommend, practically unusable

Comfortable and stays cool
Color: White-cooling Basic, Size: Queen(Pack of 1)
Great pillow. When i opened it, i noticed a strange smell, i assumed its the smell of whatever they use to make the pillow stay cool. You have to fluff it for a good amount of time to make sure the cooling agent spreads well in the foam. Is what i assumed atleast. Its a perfect amount of softness for me. Pair it with some bamboo pillow cases and you got a good night of sleep
