SLEEP ZONE King Size Cooling Mattress Topper (White) — 3-Zone Plush, Deep 8–21" Pocket, Breathable

SLEEP ZONE King Size Cooling Mattress Topper is a breathable, padded, 3-zone mattress pad that adds cooling comfort, pressure support, and a deep 8–21" stretch skirt to fit most mattresses.

This premium mattress topper combines advanced cooling fabric, extra-plush fill, and an ergonomic quilting pattern to upgrade an existing mattress without replacing it. Designed to wick moisture, speed drying, and keep the sleep surface soft and resilient, the pad aims to increase nightly comfort while protecting your mattress. It’s machine washable and built with a deep stretch skirt to fit mattresses from 8 to 21 inches.

How does the SLEEP ZONE topper help keep you cool all night?

The surface uses NANOTEX Coolest Comfort Technology and an embossed finish to improve airflow and move moisture away from the body. These features together lower trapped heat and make the fabric feel fresher against skin compared with ordinary toppers.

• Moisture-wicking surface that moves sweat away from skin
• Fast-drying microfiber treated for enhanced breathability
• Embossed sport-fabric finish increases air exchange and cooling

Will this topper add cushioning and support without changing mattress feel too much?

The SLEEP ZONE topper is overfilled with 12 oz of 5D spiral fiber and uses a 120gsm brushed microfiber surface for a fluffy, hotel-like feel. Its unique three-zone quilting gives extra support across the torso while keeping head and foot edges stable, reducing sag and preserving natural alignment.

• 12 oz 5D spiral fiberfill for plush loft and bounce back
• Three-zone quilting: supportive middle, reinforced head and foot
• Cloud-shaped center quilting disperses pressure under the body

How easy is it to install and care for this mattress pad?

The elastic knitted skirt stretches to fit mattresses from 8 to 21 inches deep, and a high-quality sport elastic trim secures the pad in place. It’s fully machine washable (cold wash, tumble dry low) so regular maintenance is straightforward to keep the pad fresh and hygienic.

• Stretch-to-fit skirt designed for 8"–21" mattress depths
• 1.6" sport elastic trim for a snug, secure fit
• Machine washable for easy cleaning—avoid bleach

Is this mattress topper durable and safe to use long-term?

SLEEP ZONE draws on decades of bedding experience and produces this pad with certified materials for consistent quality. The construction combines resilient fiberfill and reinforced quilting to resist flattening while remaining breathable and washable.

• Overfilled fiber stays soft and resilient night after night
• Reinforced quilting reduces edge deformation and sagging
• Oeko-Tex–certified materials for added product safety assurance
