The ReversaTemp Pillow Protector is an engineering marvel. One side of the pillow remains cool while the other stays warm for optimized comfort. The AirXchange® microfiltration strip allows the pillow protector material to breathe but filters out particulates. The material is highly resistant to allergens, but the OmniGuard® Advance lightweight performance fabric of the pillow protector is designed to be washed and dried in high heat for maximum sanitation. You'll want to buy one for every pillow in your home once you try the ReversaTemp Pillow Protector. Order yours from Slumberland Furniture today.
