A Fully Encased Zippered Mattress Protector is a type of mattress cover that completely encloses your mattress, sealing it with a zipper. This design offers superior protection against bed bugs, dust mites, allergens, spills, and stains.

Fully encased protectors offer maximum protection for your mattress. Unlike fitted-style protectors, they enclose the entire mattress, including the sides and bottom, providing a comprehensive barrier against various potential hazards.

Standard mattress protectors often only cover the top and sides of the mattress. A fully encased version covers all six sides and usually features a zipper, offering better protection against bed bugs and allergens.

Quality fully encased mattress protectors are made with breathable materials that should not significantly affect the breathability of your mattress. Some even come with advanced technologies that wick away moisture and regulate temperature.
