SafeRest Zippered Mattress Protector - Premium 9-12 Inch Waterproof Mattress Cover for Bed - Breathable, Noiseless Washable Mattress Encasement - Queen
New to the catalog
This is the Queen version of our sealed encasement, sized for the 9-to-12-inch profiles most conventional mattresses fall into. It turns the whole mattress into a closed system: liquid cannot get in, allergens that are already inside cannot get out, and bed bugs can do neither. If you are protecting a new mattress from day one, this is the most complete way to do it.

Three layers of thinking
1
Complete 360-degree shell
One continuous cover over every face of the mattress. Where a fitted protector leaves the underside open, the encasement closes the loop — which is exactly what allergy plans and pest protocols call for.
2
Waterproof, breathable fabric
The membrane runs through all six panels, not just the top. A spill that reaches the edge of the bed is stopped at the seam line instead of wicking around it.
3
A zipper built to stay shut
Micro-teeth close tight enough to bar anything living, and the end of the zip is secured so it cannot drift open under the movement of the bed. Sealing the mattress is a one-time job, not a nightly check.
The night test
Owners with dust mite allergies usually notice the difference in the first week: mornings without the stuffy nose that never had an obvious cause. The mattress under you is the same. The air you breathe over it is not.
Care
Leave it sealed on the mattress and launder your sheets normally. For an occasional refresh, close the zipper, machine wash cold, tumble dry low, and put it back on with a second pair of hands — six sides is a two-person job on a Queen. Full care guide →
