All-In-One Zippered Boxspring Protector with Bed Bug Blocker, California King

All-In-One features technologically advanced all-purpose fabric uniquely constructed for powerful mattress protection without sacrificing breathability and comfort. After our mattress covers, mattress protectors and box spring encasements are sewn, we attach extra interior bindings to cover seams and eliminate stitch holes. This process seals the cover to help prevent bed bugs and dust mites from entering or escaping. Encasements are designed with an exclusive triple-seal closure system including an inner flap, a hook & loop corner seal, and a nylon zipper for additional security coverage. In addition to soft and breathable, noiseless knit fabric, each mattress encasement boasts waterproof and stain-resistant protection to protect against unwanted allergens, bed bugs, dust mites, spills, and incontinence so you can sleep safe, especially for those with asthma or other respiratory conditions. Available in an array of size options including twin, twin XL, full, queen, king, and california king.
