Questions and answers

Will it fit my mattress?: It is made for mattresses or box springs 15 to 18 inches deep and comes in Twin, Twin XL, Full, Queen and King. Measure your mattress depth before ordering; anything under 15 inches will fit loosely.
Is it really waterproof?: Yes. The listing describes it as waterproof and impermeable to virus carryover, so spills and accidents stay off the mattress. The polyester surface is not absorbent, so liquids pool on top until you wipe them up.
How do I wash it?: Machine wash and tumble dry, per the care instructions. Zip it closed before washing to protect the zipper, and use a low dryer setting so the waterproof membrane lasts.
Does it work for dust mite allergies?: It is sold as an allergen barrier and zips around the whole mattress, which is the setup allergy guides recommend for dust mites. Wash it every few months to keep the barrier effective.
Is $29.99 a good price?: It is the only new price listed, $29.99 at eBay as of November 7, 2026, so there is no recent range to judge it against. Comparable zippered encasements usually run $30 to $80, so it sits at the low end.
What is in the box?: One encasement in your chosen size. The mattress and box spring are not included.
