SafeRest Zippered Mattress Protector - Premium 12-15 Inch Waterproof Mattress Cover for Bed - Breathable, Noiseless Washable Mattress Encasement - Queen
4.6 (17,813 ratings — across all sizes of this protector)
Modern Queens have gotten tall. Pillow-tops, hybrids and box-top foams routinely pass the 12-inch mark, and a standard encasement simply will not close around them. This version is cut for 12-to-15-inch profiles, so the tallest beds get the same six-sided sealed protection as everything else in the line — without straining the fabric or the zipper.

Three layers of thinking
1
Cut for tall mattresses
The side panels carry the extra depth, so the cover squares up on a 14-inch hybrid instead of pulling drum-tight. A seal only works when the fabric is not fighting the fit.
2
Waterproof, breathable fabric
All six faces carry the membrane. Deep mattresses are expensive mattresses, and the barrier keeps a single accident from becoming a stain you sign over at warranty time.
3
A zipper built to stay shut
The fine-toothed zipper runs the full perimeter and locks down at the end of its travel. Once closed, the bed is closed — through sleep, stripping day and the occasional mid-year mattress rotation.
The night test
A tall mattress with a strained cover creaks at the corners; a properly sized one is silent. Fit this to the depth you actually own — measure from the top of the crown to the bottom edge — and the encasement disappears the night you install it.
Care
Wash the encasement only when needed — sealed on the bed, it stays clean under your sheets. Cold wash, low tumble, zipper closed. Check the measurement before ordering: this cut is for 12 to 15 inches, and our 9-to-12 version covers the standard profiles. Full care guide →
