Comfy pillow
Color: White-cooling Basic, Size: Standard(Pack of 1)
I love this pillow! It comes with extra stuffing so you can get the firmness how you like it. I’m a side sleeper so I need a pillow that is thick enough for me to be able to sleep on my side and this pillow does the job. It is pretty cool. I do get hot when I sleep and I’ve noticed a little bit of a difference. I also think it’s very comfortable to sleep with. Would recommend.

helped treat my sore neck
Color: White-cooling Basic, Size: Camping Pillow(Pack of 1)
This pillow — after dialing in the right amount of shredded foam — has greatly helped my sore neck. Initially, I had to remove some foam. Then I gradually added foam until it reached optimum comfort and support. It is also CPAP-friendly — especially when I position my head near the pillow's edge. (I am a left-side sleeper.) I like the travel size because I use a bulky hugging pillow to ease stress on my shoulder and elbow. That makes my side of the bed feel cramped if using a larger head pillow. A smaller pillow is easy to flip end-to-end in the middle of the night. I have spent lots of money on pillows over the years, but this is the best I've ever had for relieving [1] neck pain and [2] CPAP mask seal problems. Very comfortable, supportive, and affordable. I did not notice any unpleasant smell — and I am usually sensitive to that kind of thing. Would highly recommend.

Great pillows at a great price.
Size: Queen - Pack of 2, Style: Soft, Configuration: Pillow
I ordered these to go in decorative pillow cases. The price was right. They are surprisingly comfortable, though--may just become my new go-to pillows! Not too soft...not too firm...juuuust right...

Excellent pillows
Size: Queen - Pack of 2, Style: Soft, Configuration: Pillow
One of the best and pillows I have ever slept on. They were incredibly soft but still incredibly supportive. The quality of the pillows were comparable to hotel pillows. I will be ordering again and I am very satisfied with my purchase.
