Linenspa Full Box Spring Encasement — Full-Size Waterproof Zippered Cover, Fits up to 10-inch, Machine Washable

Linenspa's Full Box Spring Encasement is a zippered, 100% waterproof cover that fully protects a full-size box spring from liquids, stains, and dirt.

Protecting the foundation of your mattress is as important as protecting the mattress itself. This Linenspa box spring protector wraps all six sides of a full-size box spring with an aqua-tight barrier and a zipper closure, creating a clean, dry base that extends the life and cleanliness of your bedding. Made from 100% polyester and designed to fit box springs up to 10 inches deep, the enclosure is machine washable and dryer safe on low heat for simple maintenance.

How does this cover keep liquids from reaching the box spring?

The encasement uses an aqua-tight waterproof layer bonded to polyester fabric to block liquids and prevent stains. The full 360° design and zipper closure remove gaps where spills can seep in, so liquids stay on the surface for easy cleanup.

• Waterproof barrier bonded to fabric for reliable liquid protection
• Zipper closure seals all six sides to prevent seepage
• Fits up to 10" depth to reduce exposed edges

Will this protector affect mattress comfort or fit on my bed?

The box spring encasement covers the foundation only and does not change mattress feel; it simply provides a protective shell around the box spring. Its tailored fit for a full-size box spring ensures a neat, low-profile look under your mattress and bed skirt.

• Sized specifically for full box springs to maintain a tidy appearance
• Low-profile polyester fabric won’t add bulk beneath the mattress
• Zipper closure stays discrete under the mattress for an unobtrusive fit

How do I clean and maintain the Linenspa box spring encasement?

Care is straightforward: machine wash and tumble dry on low to keep the protector fresh and functional. The durable polyester and waterproof layer are built to withstand regular washing without losing protective properties when cared for as directed.

• Machine washable for routine cleaning
• Dryer safe on low heat to preserve the waterproof layer
• Durable polyester construction designed for repeated laundering
