Keep spills and everyday messes off your mattress
A damp mattress or a cover that shifts out of place can disrupt a good night’s sleep. A zippered waterproof encasement wraps around the mattress, helping shield its top and sides from spills, sweat, and everyday accidents. This roundup of the best zip mattress cover waterproof options focuses on the details that matter at purchase time: mattress size and depth, fabric, noise, closure style, and care instructions.
These covers protect a sleep surface, but they don’t add cushioning or correct sagging like a mattress topper might. The listed choices include soft bamboo-fabric queen covers and polyester encasements for queen, full, and king beds. Product descriptions make different claims about waterproof barriers and quiet fabrics, so check the fit and care details before ordering. If a cover tends to bunch or slide, this guide to keeping a mattress topper stable covers related fit concerns. For comfort changes rather than spill protection, see this pressure-relief mattress topper review.

FAQs
Does a zippered mattress cover protect all sides?
Yes, the listed zippered encasements are described as covering all six sides. A wraparound zipper encloses the mattress, while the product details specify coverage and fit limits that vary by model.
How do I choose the right mattress depth?
Measure your mattress from the bottom edge to the top before buying. The queen Utopia Bedding cover fits mattresses up to 15 inches deep, the full-size version up to 13 inches, and the king version up to 15 inches; PlushDeluxe lists a queen fit up to 18 inches.
Are waterproof zippered mattress covers noisy?
Several options are described as noiseless or non-crinkling. DreamField Linen and PlushDeluxe highlight quiet use, while Utopia Bedding describes its knitted polyester cover as non-crinkling.
Can a waterproof cover make a bed cooler?
Some product descriptions highlight breathable bamboo fabric and moisture management, but cooling results can vary by sleeper and bedding setup. The DreamField Linen and PlushDeluxe queen covers feature bamboo-based fabric; neither description provides measured cooling results.
Can a mattress encasement fix a sagging mattress?
No, an encasement protects the mattress from liquids and dirt but doesn’t repair sagging or change firmness. A topper may alter surface comfort, though it cannot reliably correct a deeply sagging support core.
How should I wash a zippered waterproof cover?
Follow the care label for the exact cover. Utopia Bedding lists machine washing and low-heat tumble drying, while DreamField Linen specifies a cold, gentle cycle and low-heat drying; its instructions also say not to bleach or dry clean.
