Essential protection for your king mattress
Secure your investment
A king mattress or topper can be a significant investment and a shared ecosystem - a place for couples, kids, and even pets. Over its lifetime, that large surface can accumulate dead skin cells, sweat and allergens, creating an environment that can compromise not only your investment but your health.
Protecting that vast surface area isn't just about guarding against spills, it’s a necessary step in preserving a clean and hygienic place to rest. That’s why a king size mattress protector is essential for a healthy sleep environment. A quality king waterproof mattress protector provides the shield you need, giving you the confidence for uninterrupted and refreshing sleep.
King size mattress protectors ft. toppers and pads
more surface - more chances of spills
A key to deep, restorative sleep is letting your body temperature naturally dip during the night. Our protectors are engineered to support this critical phase, using advanced cooling fabrics that draw heat and moisture away from your body. This provides a welcoming sense of comfort on any bed, but it's truly transformative for memory foam - making a king memory foam mattress protector essential for neutralizing its natural warmth. Think of this as the intelligent foundation of your bed; feel free to layer a mattress pad or a plush topper right under it, to build your perfect comfort zone, knowing your entire sleep setup is shielded by a durable king bed waterproof mattress protector.

It works, and I am comfortable.
I began sleeping on the King size Active Dry Wicking Mattress Protector a few days ago. So far, I feel dry and comfortable and clean.
Best Sleep in Years
This king mattress protector doesn't hold heat at all. I'm sleeping better than I have in years!
Better than a topper
This protector replaced a 3'' cooling topper that was on my king bed before. It achieves the same effect without taking away from the comfort of my mattress.
Helps keep bed cool
Tossing and turning less with this king bed protector. I feel like I'm sleeping much cooler than before.
Premium King Protector
You can tell this is very high quality and it's super soft. Almost has a slick surface.
Lifseaver
I bought a king memory foam mattress a few years ago and it's always slept hot, no matter what time of year. My first night of sleeping on this protector I slept so much better. MUCH cooler than ever before. My husband agrees.
Absolutely excellent!
I did not want a pillow that needed breaking in so the words soft are a bit misleading, pillow is a bit stiff. Cooling cover is worthless once a pillow protector and case went on. And as with all memory foam things it has an odor. This is not a bad pillow for someone who needs more support.
