What Side Sleepers Should Look For on the Spec Sheet

Three structural details prevent morning neck stiffness and hot ears.

  1. 01
    2-Inch Gusseted Sidewalls
    A gusseted edge (like on the Coop EdenCool+) keeps fill from migrating away from the edges when your head rests near the rim.
  2. 02
    5.0 to 6.5 Inches of Uncompressed Loft
    Anything thinner than 4.5 inches forces a side sleeper's head to tilt downward toward the mattress.
  3. 03
    Shoulder Recess or Extra Fill Pouch
    Coop includes an extra 0.5 lb bag of fill so broad-shouldered side sleepers can build a taller, firmer loft.
  4. 04
    Pin-Core or Cross-Cut Airflow
    Because side sleepers bury one side of their face into the pillow, ventilated cores prevent heat buildup around the ear and jaw.

Questions

Should a side sleeper get the Purple Harmony Medium (6.5 in.) or Low (5.5 in.)?

Most average-to-broad-shouldered side sleepers and anyone sleeping on a medium-firm or firm mattress should choose the 6.5-inch Medium loft. Petite side sleepers on plush pillow-top mattresses where the shoulder sinks deeply may prefer the 5.5-inch Low loft.

How is the Coop Original Cut-Out different from the Coop EdenCool+?

The Coop Original Cut-Out has a crescent curve along one long edge so your shoulder tucks directly beneath the pillow, whereas the Coop EdenCool+ is a rectangular 2-inch gusseted pillow upgraded with a phase-change outer shell and cooling gel inner liner.

Overall Adjustable Cooling
