Linenspa Premium Encasement Mattress Protector review

Linenspa's Premium Encasement is the budget answer for anyone who needs a zippered cover quickly. A twin was $24.99 when we checked, a fraction of the price of the certified picks, and Linenspa ships it free in 1 to 3 business days. The cover is a smooth 100% polyester surface with a 100% polyurethane waterproof backing on the top, sides and bottom, and the zipper fully encloses the mattress. Linenspa says this keeps the mattress safe from bed bugs, liquids, allergens and dust mites, and that the backing is quiet and does not change how the bed feels. It carries a 10-year limited warranty and is HSA/FSA eligible. The limits are real, though: the page cites no lab certification for bed bugs, describes no locking zipper, and gives two different maximum depths, 12 and 14 inches. Treat it as a preventive barrier for a rental or a guest bed rather than the main tool after an infestation.

Travelers, students and renters on a tight budget who want a basic zippered barrier.
