How to Choose the Best Pillow for Your Sleep: A Complete Guide to Every Coop Pillow
|
Comfort is personal. What lets your neighbor sleep like a rock might leave you tossing, sweating, or waking up with a stiff neck. Yet most of us are still sleeping a one-size-fits-all pillow - one fixed loft, one fixed firmness, take it or leave it.
The truth is, "soft" and "firm" were never enough options. The right pillow depends on how you sleep, how warm you sleep, and how big you are - and it should be able to adjust to you, not the other way around. That’s the idea behind every pillow we make at Coop: instead of guessing your way through returns, you build the exact loft and feel you need, then fine-tune it as your needs change.
Here’s how to find your the best pillow in a few minutes, plus an honest look at all four pillows in the Coop lineup so you know exactly which one is calling your name.
The 3 things that actually determine your pillow
Before you compare specific pillows, it helps to know what you’re solving for. Nearly every “which pillow is right for me” question comes down to three factors:
1. Sleep position. Side sleepers generally need more loft to fill the gap between ear and mattress and keep the spine level. Back sleepers usually want medium support that cradles the neck without pushing the head too far forward. Stomach sleepers tend to do best with something low and soft so the neck doesn’t crank upward. Combination sleepers need a pillow forgiving enough to work in more than one position.
2. Sleep temperature. If you wake up flipping your pillow to the “cool side” or kicking off the covers at 2 a.m., temperature regulation matters as much as shape. Traditional solid memory foam sleeps hot because it’s dense; gel-infused foam, latex, and down alternative fills all move air more effectively.
3. Size and loft needs. Broader shoulders and larger frames typically need more fill and a higher loft for the neck and spine to stay aligned; smaller frames often want less. This is where most off-the-shelf pillows fail—you can’t add or remove filling from a standard pillow no matter how badly you need to.
An adjustable pillow solves all three at once, because you’re not locked into one loft or one firmness on day one. You can add fill for more support, remove it for a lower profile, and rebalance it any time your needs change.
Meet the lineup: 4 Coop pillows, 4 different sleep needs
All four Coop pillows share the same core idea—fully adjustable fill, a 100-Night Sleep Better Guarantee, and a 5-year warranty—but each is built around a different combination of feel and temperature control.
The Original: well-loved support for nearly everyone
The Original Adjustable Pillow is Coop’s best-selling and most-recommended pillow—it’s Consumer Reports Recommended and carries more than 17,000 reviews at a 4.7-star average. Its medium-firm fill of cross-cut memory foam and microfiber makes it a strong match for firm-pillow lovers and side sleepers, who make up the majority of sleepers and generally need the most loft and support.
Choose the Original if: you want a reliable, medium-firm memory foam pillow that adjusts to your position, and temperature regulation isn’t your top priority.
Eden: soft, cooling comfort for back and stomach sleepers
The Eden Adjustable Pillow is Coop’s softest, most luxurious pillow, built from cooling gel bead-infused memory foam and microfiber. Where the Original leans firm, Eden leans plush—making it a favorite for back and stomach sleepers, people transitioning off a feather-down pillow, and anyone who runs a little warm at night but doesn’t need aggressive cooling.
An upgraded edge-to-edge gusset gives Eden more structure than a typical soft pillow, so it holds its shape if you shift positions through the night instead of going flat and pinching at the edges.
Choose Eden if: you love the sink-in feel of a soft pillow, sleep mostly on your back or stomach, and want some cooling without stepping up to Coop’s most advanced cooling pillow.
Cool+: the pick for the hottest sleepers
If you’re the person perpetually flipping to the cold side of the pillow, the Cool+ Adjustable Pillow is Coop’s answer. It combines cooling gel-infused, plus-shaped memory foam and microfiber (engineered for 50% more breathability) with a cool-to-the-touch outer cover that scores a .48 out of a possible .50 on the Q-max cooling scale—the industry measure of how cool a fabric feels on contact.
Inside, a heat-wicking liner and phase-change material give one side a firmer, supercooled feel and the other a softer cushioned feel, so you can flip it to match your mood.
Choose Cool+ if: you’ve tried “cooling” pillows before and still wake up hot—this is Coop’s most advanced cooling technology, full stop.
Latex: sustainable, responsive support
The Latex Adjustable Pillow is Coop’s most sustainable pick, filled with cross-cut Talalay latex and polyester microfiber processed through an eco-friendly 8-step system. Unlike memory foam, which slowly contours and holds its shape, latex is naturally bouncy and responsive—it pushes back to ease pressure points rather than letting you sink in, and its open-cell structure moves air naturally without gels or cooling additives.
Choose Latex if: you want responsive, springy support that eases pressure points, sleep hot but prefer natural breathability over gel cooling, or sustainability is a priority in what you buy.
Why adjustability matters more than “soft” or “firm”
Here’s the thing that makes all of this easier than it sounds: you don’t have to get it perfect on the first try. Every Coop pillow comes with extra fill specifically so you can dial in the loft and firmness after you’ve slept on it a few nights. Want more support for side sleeping? Add fill and concentrate it toward the center. Love the softness of Eden but want a bit more height? Add some of the included fill until you find your balance. Need less loft as the seasons—or your mattress—change? Remove some.
That’s the real advantage of an adjustable pillow: it’s not a single bet on “medium” that you’re stuck with for years. It adjusts as you do.
