Summary
Shredded memory foam fill lets you add or remove stuffing for a perfect fit. Consistently tops Reddit threads and expert lists alike for all sleep positions.
Wirecutter's explicit pick for stomach sleepers — softer and lower-loft than shredded foam options. Three removable inserts let you fine-tune thickness until it's just right.
Pros
- Fully adjustable loft — add or remove fill to dial in exact height
- Shredded memory foam + microfiber blend gives down-like plushness with real support
- CertiPUR-US certified, hypoallergenic fill
- Works for side, back, and stomach sleepers
- Three removable inserts allow precise loft customization for stomach sleeping
- Softer down-alternative fill is gentler on neck for prone sleepers
- Wirecutter's explicit top pick for stomach sleepers after hands-on testing
- Works for back and side sleepers at higher insert counts
Cons
- Takes time to break in — some users don't love it immediately
- Can feel lumpy until you adjust the fill to your preference
- Pricier than basic polyester pillows
- Less supportive than shredded foam for side sleepers
- Down-alternative fill may compress faster than foam over time
- Primarily available through Sleep Number retail
Our take
If you only buy one pillow, make it the Coop. It's the rare product that Reddit obsessives and sleep experts both agree on — the adjustability alone eliminates the guesswork that makes pillow shopping a nightmare.
Stomach sleepers are chronically underserved by pillow recommendations, and this is the rare pick designed specifically for them. The insert system is genuinely clever — one tester called it 'pretty much perfect' after removing a single layer.
