Our take on the Guardmax Terry Cotton Zippered Mattress Encasement - Twin XL Size - 100% Waterproof and Bed Bug Proof Mattress Protector - Absorbent Six-Sided Mattress Cover (Terry Cotton, Twin XL)

The Guardmax Terry Cotton Zippered Mattress Encasement is a six-sided, fully zippered cover that seals a Twin XL mattress on all sides. The terry cotton surface is soft and absorbent, and a waterproof backing keeps liquids and stains out of the mattress. The zipper runs the full length with an overlapping flap meant to keep bed bugs from getting through. It suits people with allergies, bed bug concerns, or a mattress they want to keep clean. Against plain fitted protectors, it covers the bottom and sides too, but it is heavier to install and the terry surface adds some bulk under sheets.

Questions and answers

Does it really protect all six sides of the mattress?
Yes. It is a full encasement, so it covers the top, bottom and all four sides, not just the sleeping surface.
Will it stop bed bugs?
The zippered closure with an overlapping flap is designed to seal the mattress so bed bugs cannot get in or out. Close the zipper fully and seat the flap.
Is it waterproof on the sides too?
The waterproof backing covers the encasement, so spills on the top and sides are blocked from reaching the mattress.
How does it compare with a fitted mattress protector?
A fitted protector only covers the top. This one seals the whole mattress, which is better for bed bugs and allergens but heavier to install.
Can it go in the washing machine?
Terry cotton encasements of this type are typically machine washable on a gentle cycle and tumble dried low. Check the care label before washing.
Does the terry surface change how the mattress feels?
It adds a soft, slightly thicker layer under sheets. Most buyers find it comfortable, though some notice extra warmth.
