[Standard Size] This cooling pillow measures 24" x 16" x 5" – the classic standard size (distinct from King sizes and Queen sizes). Packaged in a beautiful colorful box, Our bed pillow is an ideal gift for family and friends. An essential for bedrooms, hotels, dorms, and college housing. [All-Night Cooling] The pillowcase features NASA-inspired PCM temperature-control technology. Like ice cubes in water, wax bead-like capsules react to your touch for instant cooling that lasts up to 8 hours. The core uses unique AirMicro no-pressure memory foam with 95% open-cell structure – significantly more breathable than standard pillows. A must-have for hot sleepers. [Dual Comfort] Experience all-night coolness on the cooling+ side, while the cooling side offers softer, breathable comfort. This reversible design lets you choose your perfect sleep surface for consistently refreshing rest. [Premium Quality] Lab-tested through 80,000 compression cycles with under 1% height loss. Built to last roughly 5 years. The standard size works for all sleep positions (side/back/stomach), while premium memory foam delivers excellent head/neck/shoulder support to relieve pressure points. [Easy Care] Features an oversized zipper for quick pillowcase removal. Just unzip, toss the cover in the wash, and refresh with ease. Note: Do not wash the cooling core.
