Sleep Philosophy Waterproof Full-Size Sofa Bed Mattress Protector 54 x 72 Quilted OEKO-TEX, 8-inch Deep Fit

Sleep Philosophy's Waterproof Sofa Bed Full Size Mattress Protector (54 x 72") is a quilted, OEKO-TEX certified cover that adds soft padding and a moisture-resistant barrier to sofa bed mattresses up to 8" deep.

This mattress pad is made to convert a thin sofa bed mattress into a more comfortable, protected sleeping surface while guarding against spills, stains and everyday wear. Diamond quilting provides a light cushioning layer; a 3M Scotchgard Moisture Management treatment helps wick away dampness and makes stains easier to release in the wash. The elastic pocket skirt is designed specifically for full-size sofa beds (54 x 72 inches) with up to an 8" depth, ensuring a snug, non-slip fit while remaining machine-washable for simple care.

How does this protector improve comfort on a sofa bed?

The protector adds a lightly padded layer through classic diamond quilting that softens the feel of thin sofa bed mattresses without changing mattress height significantly. The fill cushions pressure points for a more pleasant short- to medium-term sleep surface, and the quilt keeps the padding evenly distributed.

• Diamond quilting for uniform padding and a tailored look
• Light cushioning that improves initial comfort on thin mattresses
• Doesn’t significantly alter mattress height or fit

Is it really waterproof and stain-resistant?

The pad includes a waterproof inner layer to block liquids from reaching the mattress while a 3M Scotchgard Moisture Management Treatment helps liquids wick away and makes stains easier to wash out. Note that the waterproof lining can produce a faint rubbing noise when you shift on the surface, which is normal for barrier-style protectors.

• Waterproof lining prevents spills from penetrating the mattress
• 3M Scotchgard treatment improves stain release during washing
• Minor surface noise possible due to protective membrane

Will this fit my sofa bed mattress and stay in place?

This protector is cut and sewn specifically for full-size sofa bed mattresses (54 x 72 inches) with a mattress depth up to 8 inches. It features an all-around elastic pocket skirt engineered to grip the mattress edges and minimize shifting, keeping the pad neatly secured during use and while folding or unfolding the sofa bed.

• Designed exclusively for full sofa bed mattress size 54 x 72 inches
• 8" deep elastic pocket for a snug, enclosed fit
• All-around elastic reduces slipping and movement

How do I care for the mattress protector?

Maintenance is straightforward: machine wash cold and tumble dry low, removing promptly to preserve the quilt and elastic. Avoid bleach and ironing to protect the waterproof membrane and the Scotchgard treatment so the protector retains its performance and appearance.

• Machine wash cold; do not bleach
• Tumble dry on low heat and remove promptly
• Do not iron to preserve waterproof layer and treatments
