Huhu Sleep Cooling Pillow 16x24x5 in — 5" Memory Foam for Back & Side Sleepers, Reversible PCM Cooling Cover

The Huhu Sleep Cooling Pillow is a 5-inch standard memory foam pillow with a reversible cooling case and high-breathability foam designed to keep back and side sleepers cooler and supported through the night.

This pillow combines a NASA-inspired phase-change-material (PCM) cooling cover with an AirMicro open-cell memory foam core to deliver a balance of temperature regulation and pressure-relieving support. Packaged in an attractive box, it’s sized at 16" x 24" x 5" — a standard pillow dimension suitable for bedrooms, dorm rooms, guest beds, and hotel use. The reversible cover gives a cooler, firmer surface on one side and a softer, breathable option on the other.

How does this pillow manage overnight heat?

The pillowcase uses PCM cooling beads that react to skin temperature to pull heat away and provide a noticeable cooling effect. Combined with an AirMicro foam core that has a 95% open-cell structure, airflow and moisture wicking increase, lowering the chance of trapped heat.

• PCM cooling capsules activate on contact for lasting coolness up to several hours.
• Open-cell AirMicro foam improves ventilation compared with traditional foam.
• Reversible cover offers an extra cool side and a softer breathable side.

Will it support my head and neck for side or back sleeping?

At 5 inches thick, the foam core provides a medium-to-firm support profile that helps align the head and neck for most back and side sleepers. The memory foam contours to the sleeper’s shape to relieve pressure points while maintaining lift where needed.

• 5" thickness suitable for side and back alignment.
• Memory foam contours to reduce localized pressure on shoulders and neck.
• Lab-tested durability preserves height and support over years of use.

How durable and easy to care for is the Huhu Sleep pillow?

The pillow core has been lab-tested through extensive compression cycles with minimal height loss, indicating multi-year performance. Care is simplified by an oversized zipper: the cooling cover is machine-washable while the foam core should be kept dry and spot-cleaned only.

• 80,000 compression-cycle testing with under 1% height loss.
• Designed lifespan around five years under normal use.
• Removable, machine-washable cooling cover; do not submerge the foam core.

What makes this pillow a flexible choice for different sleeping situations?

Its standard 16" x 24" size fits most pillowcases and bedding setups, and the reversible cover lets sleepers switch surfaces depending on temperature or preference. Gift-ready packaging and universal sizing make it a practical pick for bedrooms, guest rooms, dorms, and travel between homes.

• Standard pillow size fits existing bedding and pillow protectors.
• Reversible cooling/soft sides adapt to seasonal or nightly comfort needs.
• Attractive boxed presentation suitable for gifting.

Who is this for: The Huhu Sleep Cooling Pillow is designed for hot or temperature-sensitive back and side sleepers who want breathable memory foam with a reversible cooling surface. It’s also a good option for people furnishing dorms, guest rooms, or anyone seeking a standard-sized, long-lasting pillow with easy-to-clean covers.
