Coop Home Goods King Cool Side Pillowcase — Two-Sided Cooling Pillow Cover with Cozy Lulltra & Zippered Fit

The Coop Home Goods Cool Side Pillowcase (King) is a two-sided pillow cover offering an ultra-soft cozy side and a cool-to-the-touch side to help regulate head temperature for more comfortable sleep.

If you overheat at night or want a soft cover that adapts to changing temperatures, this king-size pillowcase combines breathable materials and a thoughtful shape to suit side, back, and stomach sleepers. The reversible design pairs a plush Lulltra fabric on one face with a cooling blend on the other, while OEKO-TEX Standard 100 certification confirms the fabric has been tested for harmful substances.

How does the two-sided design improve comfort?

The reversible construction gives you instant temperature options: a cushioned, cozy face for cool evenings and a vented, cool-feel face for warm nights. Swapping sides is immediate and requires no extra accessories, so one pillow meets different seasonal needs.

• One side: viscose rayon/polyester Lulltra for softness and warmth.
• Opposite side: polyethylene/polyester blend that feels cool to skin.
• Zipper closure secures the cover without shifting during sleep.
• Reversible design replaces need for two separate pillowcases.

Will this fit my pillow and stay in place all night?

The Cool Side pillowcase uses a rectangle shape tailored to the Coop original pillow profile and standard king dimensions, so it hugs the contours of side, back, and stomach sleepers. A built-in zipper provides a snug fit and simple removal for washing, preventing slippage and bunching.

• Standard king size fits common king pillows and Coop Original Pillow.
• Durable zipper keeps the cover securely closed overnight.
• Tailored rectangle shape minimizes excess fabric and shifting.
• Designed for sleepers of different positions without altering pillow feel.

How easy is it to care for the Cool Side pillowcase?

Maintenance is straightforward: the cover is machine washable so you can clean it regularly without special treatments. Fast laundering helps reduce sweat and oil buildup, keeping your pillow fresher between deeper cleanings.

• Machine washable on normal cycles for quick cleaning.
• Durable fabrics maintain softness and cooling properties wash after wash.
• Keep a spare to swap during laundry days for continuous comfort.
• Zipper allows easy removal and reapplication before washing.

Is the fabric safe and what materials are used?

The pillowcase is OEKO-TEX Standard 100 certified, meaning it has been tested for the absence of many harmful chemicals. Materials combine a rayon/polyester Lulltra face with a polyethylene/polyester cool face to balance plush feel and breathable performance.

• OEKO-TEX Standard 100 certified for tested safety.
• Lulltra: viscose rayon blended with polyester for softness and breathability.
• Cool side: polyethylene and polyester blend for a cool touch.
• Materials chosen to manage moisture and heat around the head.

Who is this for? The Coop Home Goods Cool Side King pillowcase suits hot sleepers who need a quick way to cool down, people who prefer one pillowcase that works year-round, and owners of Coop standard pillows seeking a fitted, zippered cover. It’s also a good match for anyone who prioritizes OEKO-TEX tested fabrics and low-maintenance bedding that stays comfortable night after night.
