Linenspa Zippered Waterproof Box Spring Encasement — Queen, 360° AquaTight™ Protection, Quiet Polyester

Linenspa's Zippered Waterproof Box Spring Encasement is a fully sealed 360° cover that protects box springs from liquids, spills, and dust while remaining quiet and soft under bedding.

This zippered encasement wraps all six sides of a standard box spring up to 10 inches deep with Linenspa’s AquaTight™ waterproof barrier. The polyester outer layer stays smooth and noiseless so the cover won’t change how your mattress feels, and the zipper closes firmly to lock out moisture and debris. It’s machine washable, dries on low heat, and is supported by a 10-year limited warranty for long-lasting use. Available sizes include Twin, Twin XL, Full, Full XL, Queen, Split Queen, King, and Cal King.

How does this encasement keep my box spring dry?

The core of protection is the AquaTight™ waterproof layer that sits between the box spring and anything spilled onto your bed. Liquids are blocked from penetrating to the box spring, protecting structural materials and extending its life. Because the zipper closes fully around the cover, there are no open seams that can admit moisture.

• AquaTight™ waterproof membrane blocks spills and accidents
• Full zipper closure seals all edges to prevent seepage
• 360° coverage protects top, sides, and bottom of the box spring

Will the encasement change the feel or sound of my bed?

No — the outer layer is soft polyester designed to stay quiet and smooth under sheets. Unlike some waterproof protectors that crinkle or rustle, this cover is engineered to remain noiseless and breathable so it won’t alter sleeping comfort. The slim profile keeps the look and feel of your bed natural.

• Polyester surface provides a soft, fabric-like touch
• Quiet construction avoids crinkling or rustling sounds
• Breathable design helps maintain normal mattress airflow

How easy is it to install, remove, and clean?

Installation is quick: slip the encasement over the box spring and zip it closed — most setups take only minutes. When it needs cleaning, place it in the washing machine and tumble dry on low heat. The durable construction and machine-washable fabric make upkeep straightforward for everyday households.

• Slides on and zips up in minutes for fast installation
• Machine washable; tumble dry on low heat
• Durable materials stand up to regular laundering

What sizes and warranty options are available?

The cover fits standard box springs up to 10 inches deep and comes in a full range of mattress sizes, including split queen for adjustable bed setups. Linenspa backs the encasement with a 10-year limited warranty, offering added assurance of long-term performance and workmanship.

• Fits box springs up to 10" deep in Twin through Cal King
• Split Queen option available for divided foundations
• 10-year limited warranty for product confidence

Who is this for: This encasement is ideal for anyone wanting reliable moisture protection for a box spring without changing bed comfort — parents, pet owners, people with spill-prone bedrooms, or homeowners preserving an expensive foundation. It’s also a practical choice for guest rooms, rentals, and shared living spaces where easy cleaning and durable protection matter most.
