Coop Original Adjustable Pillow review

Coop's Original Adjustable Pillow ranks first because it solves the main problem side sleepers with neck pain have: finding the right height. The pillow comes overfilled with a blend of cross-cut memory foam and microfiber, and you remove or add fill through a zipper until your neck sits level with your spine. Coop includes extra fill in the box, so you can go higher as well as lower. Besides the rectangular Classic, Coop sells a Crescent shape and a Cut-Out shape, which leaves room for the shoulder. Both the pillow and its Lulltra cover are machine washable, and the foam is GREENGUARD Gold and CertiPUR-US certified. The 100-night Sleep Better Guarantee and 5-year warranty are among the most generous terms on this list. The queen Classic was $88.77 when we checked. The main caution is patience: plan on a few nights of adjusting before it feels right.
