Know before you buy
This protector covers the top surface and all four sides of your mattress. It acts as a barrier against liquids, allergens, and dust mites on these surfaces, though it does not fully encase the bottom of the mattress.
Yes, but the cooling effect is most effective when the protector is placed directly over the mattress. If you place a thick topper on top of the protector, you may not feel the full benefit of the HyperChill technology.
No. The H2Pro membrane is designed to be quiet and flexible, so it won't create the plastic-like crinkling sounds often associated with traditional waterproof protectors.
The protector is designed with a universal fit and thick elastic, allowing it to accommodate mattresses ranging from 6 to 22 inches deep. It will stay snug on both low-profile mattresses and extra-thick pillow-top models.
You can machine wash the protector on a gentle cycle and tumble dry it on low heat. Avoid using bleach or harsh chemicals, as these can damage the waterproof membrane over time.
Yes, the fabric is hypoallergenic and acts as a physical barrier against dust mites and other common household allergens, helping to create a cleaner sleep environment.
