HOSPITOLOGY PRODUCTS Box Spring Encasement Twin XL 38 x 80 - Zippered Hypoallergenic Bed Bug & Dust Mite Barrier

This bed protection cover combines a stretchable polyester knit with a secure zipper closure to fully encase the box spring while remaining breathable and machine washable. Independently lab-tested and backed by a 5-year limited manufacturer’s warranty, it’s designed for easy installation and routine cleaning. The Twin XL dimension fits box springs 38" wide and 80" long with a depth range of 9" to 11" and ships with an installation kit to simplify the fit.

How does this encasement block bed bugs and dust mites?

The cover creates a full barrier over the box spring so pests and particles cannot pass through fabric gaps or seams. A zippered closure with a secure overlap reduces entry points, while the tightly knit polyester weave limits microscopic passage.

• Full-coverage fit seals the entire box spring surface and sides
• Zipper closure with protective flap to reduce zipper gaps
• Tightly woven 100% polyester knit to resist particle penetration

Is it easy to install and maintain?

Yes—the stretchable knit fabric and included installation kit make positioning the cover quick, even on heavier box springs. When soiled, the encasement is machine washable and dryable so you can clean it on a schedule without special care.

• Stretch material slides over corners for a snug fit
• Installation kit helps tuck and secure excess fabric
• Durable for routine machine washing and tumble drying

Will this fit my bed and mattress setup?

This model is sized for Twin XL box springs measuring 38" x 80" and accommodates depths between 9" and 11". If your box spring falls within those dimensions, the cover will fit securely; measure before purchasing to ensure compatibility.

• Designed specifically for Twin XL standard box springs
• Accepts box spring depths from 9" to 11" comfortably
• Elastic stretch allows for minor size variation without bunching

What warranty and testing support this product?

The encasement has undergone independent laboratory testing and comes with a 5-year limited manufacturer’s warranty. These protections provide assurance of material performance and manufacturing quality over time.

• Independently lab-tested for barrier performance
• 5-year limited warranty against manufacturing defects

It’s particularly useful when you need a zippered, easy-to-clean barrier that fits a 38" x 80" Twin XL box spring with 9"–11" depth.
