CrystalTowels Waterproof King Mattress Protector — 6-Sided Zipper Encasement, Breathable & Machine Washable

All-Around King Mattress Protection That Keeps Sleep Surface Fresh

The CrystalTowels Waterproof King Mattress Protector features a slim TPU waterproof layer designed to block spills, sweat, and everyday moisture from reaching the mattress. The result is a sleep surface that stays soft to the touch and comfortable, even after active nights or busy days. This protective layer works quietly in the background, so you can rest without distraction while maintaining a crisp, clean bed environment.

Complete Coverage with a Six-Sided Encasement

Unlike standard toppers, this protector surrounds the entire mattress with a 6-sided encasement. A blend of stretchable fabric and a reinforced zipper ensures a secure, snug fit that stays in place—even with restless sleepers and frequent sheet changes.

Breathable, Quiet Comfort

Soft polyester fabric promotes air flow to keep the surface breathable and comfortable. The material lies smoothly under sheets and avoids plastic-like crinkles, helping promote a calmer, quieter night’s rest.

King-Size Fit You Can Count On

Designed for King mattresses measuring 78 x 80 inches and up to 16 inches deep, the protector offers a reliable, secure fit thanks to elasticized sides and a durable zipper that helps maintain the encasement’s position over time.

Easy Care with Durable Protection

Built for everyday use, the cover is machine washable and designed to hold its shape and performance through repeated cleanings. You can refresh the surface without sacrificing protection or comfort.
