Linenspa Box Spring Encasement — Twin XL Waterproof Zippered 360° Protection

The Linenspa Box Spring Encasement is a zippered, 100% polyester cover that delivers full 360° waterproof protection for Twin XL box springs.

Keep the foundation of your bed dry and clean with a snug, easy-care encasement designed for long-lasting protection. Linenspa’s Twin XL box spring cover uses an aqua-tight barrier to prevent liquids and stains from penetrating the box spring while enclosing all six sides with a secure zipper closure. The material feels soft to the touch and is machine washable for straightforward upkeep, making it a practical addition to any bedroom or guest room.

How does this encasement protect my box spring from spills?

The encasement features a waterproof layer integrated into 100% polyester fabric that blocks liquids from reaching the box spring. Because it wraps all six sides and zips closed, it prevents both surface spills and accidental seepage from damaging the foundation.

• Waterproof aqua-tight barrier resists liquids and stains.
• Zippered closure secures the cover around the entire box spring.
• Fits up to 10" depth for a snug installation.

Will it change the feel or comfort of my bed?

This encasement is focused on protection rather than altering mattress comfort, so it won't significantly change how your mattress feels. The polyester fabric provides a smooth surface against the mattress while remaining thin enough to stay out of the way of bedding and sheets.

• Low-profile material minimizes added bulk under mattress.
• Soft polyester surface maintains a neat foundation for bedding.
• Designed for compatibility with mattress toppers and pads.

How easy is care and maintenance for this box spring cover?

Linenspa built the encasement for simple, routine cleaning: toss it in the washing machine and dry on low heat. The fabric retains its water-blocking performance through standard home laundering, so you can refresh bedding protection without special treatments.

• Machine washable for regular cleaning.
• Tumble dry on low heat to maintain shape and barrier.
• Durable polyester construction stands up to repeated wash cycles.
