Sierra Sleep Advanced Twin XL Mattress Protector

The Sierra Sleep Advanced Protector is a Twin XL mattress protector designed to guard your mattress against everyday wear while keeping sleep cool and comfortable. Made for Ashley's Sierra Sleep bedding line, it uses an advanced moisture wicking fabric that stays cool to the touch, helping regulate body temperature through the night instead of trapping heat the way many protectors do.

Underneath that surface is a quiet, fully waterproof barrier. It shields the mattress from spills, stains, and everyday fluids without changing how the mattress feels underneath you, so you get protection without a plasticky or noisy layer between you and your bed. The fabric also helps repel dust mites, which makes it a practical addition for allergy conscious households or anyone who wants an easy way to extend the life of a mattress.

• Advanced moisture wicking, cool to the touch fabric
• Quiet, fully waterproof barrier that resists stains and fluids
• Helps repel dust mites

This listing is the Twin XL size. It is a good match for any Twin XL mattress, whether it is brand new or already in use, and gives a simple way to add a protective layer without sacrificing comfort or quiet.

Care

Machine wash and tumble dry on low. The waterproof barrier is built to hold up over repeated washes, so the protector keeps doing its job over the long haul, and it carries a 10 year manufacturer warranty for added peace of mind.
