Utopia Bedding Zippered Mattress Encasement Queen - 100% Waterproof and Bed Bug Proof Mattress Protector - Absorbent, Six-Sided Mattress Cover

Utopia Bedding builds this queen encasement from knitted polyester, a fabric with enough stretch to pull over a mattress without fighting the corners, and it keeps a soft surface under the sheets. A TPU backing runs across every panel, so liquid stays on top of the cover instead of soaking through to the mattress underneath.

The zipper is the part that does the real work. It closes the cover on all six sides, sealing the mattress in full rather than draping over the top, and the closure is tight enough to keep bed bugs and dust mites shut out. Spills, drips and everyday accidents wipe up on the surface. When it needs cleaning, run it through the washing machine and tumble dry.

• Queen, 60 by 80 inches, with a 15 inch deep pocket
• White, 100% polyester, zipper closure
• Machine wash and tumble dry

Check your mattress depth against the 15 inch pocket before ordering. Packaging may vary between shipments.

Fitting the encasement correctly takes a few minutes but makes a difference over time. Start by removing all bedding and standing the mattress on its side if you can manage it alone, since this makes it easier to work the encasement up from the bottom and zip across without straining the closure. Once it is on, the zipper pull should lie flat against the side of the mattress rather than digging into the seam area where sheets rest. If you notice the zipper pulling or gapping after the first wash, check that the mattress has not expanded beyond the 15 inch depth rating, as some memory foam mattresses expand slightly with heat.

When storing a spare or rotating between seasons, fold it loosely and keep it in a breathable bag rather than a sealed plastic bin, which can trap moisture against the fabric. This product suits anyone who shares a bed with a partner prone to night sweats, parents putting a mattress in a child's room, or anyone setting up a guest bed that sees irregular use and needs reliable protection between visits. If you are comparing encasements, the key distinction to check is whether a competing product covers all six sides or only five, since a fitted-style cover leaves the bottom exposed.
