Spoiler: People are sleeping better

The Coop pillow was recommended by my physical therapist after I was thrown from a treadmill and injured my C5, 6, & 7 vertebrae causing severe nerve pain. The pillow has been a life saver! I was able to adjust it according to my specific needs and it is the most comfortable pillow I have ever slept on, it’s like sleeping on a cloud! I fall asleep faster and stay asleep longer and I know it’s all because of the coop pillow!

I look forward to laying my head down every night on this pillow. It maintains its shape perfectly. My boyfriend kept stealing it from me, so I bought him his own Coop pillow for his birthday. Our entire bed is now Coop... whoops! I will never buy another brand of pillow.

This pillow is the BEST I've ever tried. I'm a side and stomach sleeper and the cut-out as well as the ability to adjust the amount of fill make this pillow stand out from others and keep me super comfortable at night. I've had mine over 2 years now and plan on replacing it with the same one when it's at the end of it's life, but for now - it's still going strong! LOVE IT - so happy I decided to invest in comfortable sleep.

I always thought the cutout thing was unnecessary- being a side sleeper, I love the shape. my shoulders feel so much less tension. The fluff of the stuffing is just right, you don’t sink too much but it also doesn't feel firm. BEST PILLOW EVER!

I have tried multiple different pillows and nothing was quite right. I deal with TMJ and neck pain so shoulder placement is huge for a good nights sleep for me. The crescent pillow really makes such a difference. I’ve had it for about a year now and can attest to it still being great.
