SafeRest Box Spring Encasement - Queen 9" Waterproof, Breathable, Noiseless

SafeRest Premium 9" Box Spring Encasement is a vinyl-free, waterproof, breathable cover that fully seals a queen-size box spring up to 9 inches with a noiseless polyester surface and 360° Secure micro-zipper.

Protecting the box spring beneath your mattress helps extend the life of your sleep system and prevents fluids, dust, pests, and allergens from reaching expensive foundations. SafeRest redesigned the box spring encasement to combine a soft, quiet polyester outer layer with a tested waterproof membrane backing — all without vinyl — for comfort and dependable protection. The product is machine-washable and engineered to install easily on standard 9" queen box springs.

How does this encasement keep a box spring waterproof while staying breathable?

The SafeRest encasement uses a dual-layer approach: a tightly woven polyester outer fabric for softness and durability, backed by a waterproof membrane that blocks fluids but allows air to pass. That combination prevents liquid penetration while reducing the trapped-heat feel found in some covers.

• Polyester surface provides a smooth, quiet touch and resists wear.
• Waterproof membrane backing blocks spills and stains without vinyl stiffness.
• Breathable construction promotes airflow to limit moisture buildup.

How secure is the 360° Secure micro-zipper and will it stay closed?

SafeRest’s patented 360° Secure micro-zipper minimizes the chance of accidental opening by enclosing the zipper traveler with a fold-over Velcro flap at the end. The micro-zipper itself is low-profile and designed to lie flat so it won’t catch or produce noise during movement.

• 360° Secure fold-over Velcro covers the zipper traveler completely.
• Micro-zipper runs around the perimeter for full six-sided protection.
• Noiseless fit that reduces zipper rattling when you move on the bed.

Will this fit my box spring and how do I care for it?

The encasement is built to fit box springs up to 9 inches deep and is available in queen sizing. Installation is straightforward: wrap the cover around the box spring and close the zipper, then secure the Velcro flap. Care is simple — machine wash with sheets on gentle, tumble dry low — no ironing needed.

• Fits up to 9" box spring height; check your foundation depth before buying.
• Machine-washable for easy cleaning and maintenance.
• Tumble dry on low heat; do not iron to protect the waterproof membrane.

What practical benefits will I notice day to day?

Beyond spill protection, the encasement helps maintain a cleaner sleeping environment by blocking dust, allergens, and pests from lodging in the box spring. The polyester surface is quiet and comfortable against the mattress, and because it’s vinyl-free, it avoids a plastic odor or stiff feel often associated with cheaper covers.

• Prevents fluid damage that can lead to costly replacement.
• Reduces allergen buildup inside the box spring structure.
• Vinyl-free design keeps the cover soft and odor-free.

Who is this for: The SafeRest Premium 9" Box Spring Encasement is suited for anyone who wants reliable, full-wrap protection for a queen box spring without sacrificing breathability or quiet comfort. It's a practical choice for families, pet owners, allergy-sensitive sleepers, or anyone preserving a quality mattress set and foundation.
