Sierra Sleep Advanced Queen Mattress Protector

The Sierra Sleep Advanced Protector is a waterproof mattress cover built for everyday protection without changing how your mattress feels. Made from an advanced moisture-wicking, cool-to-the-touch fabric, it works quietly in the background, keeping you comfortable while it defends your mattress against spills, stains, and everyday wear.

Built for Real Protection

• Advanced moisture-wicking, cooling fabric surface
• Quiet waterproof barrier that repels liquids and stains
• Helps guard against dust mites
• Fits mattresses up to 18 inches thick
• Compatible with hybrid, memory foam, and innerspring mattresses, including power base setups

Because the waterproof layer is engineered to stay quiet and unnoticeable, you get the peace of mind of a protector without the crinkle or stiffness of older styles. The breathable, moisture-wicking surface helps regulate temperature through the night, so the mattress underneath sleeps the way it is supposed to, night after night.

A protector like this one is a simple, affordable way to extend the life of a mattress. It is a good fit for kids' rooms and family beds, guest rooms that see a lot of different sleepers, and homes where allergies or dust sensitivity are a concern. Slipping it on before the mattress ever sees its first spill is the easiest way to keep that mattress looking and feeling new for years.

Care is simple. The cover is machine washable, making it easy to keep fresh between deep cleans, and it goes on and off without any special tools or fuss. It is backed by a manufacturer's 10 year warranty, so it is built to hold up over the long run, not just the first few months.

This listing is for the Queen size protector, packed 4 to a case, a practical option for households or properties furnishing more than one bed at once.
