Mattress Encasements

A mattress encasement fully encloses the mattress with a zippered barrier that protects all sides, whereas a mattress protector or pad typically covers only the top surface; encasements are designed to block bed bugs, dust mites, liquids, and allergens more completely

Measure mattress length, width, and thickness including any pillow top; choose an encasement specified for your mattress size and depth or with stretch/elastic panels that accommodate your measured thickness to ensure a snug, zipper-sealed fit

Common materials include breathable waterproof fabrics (polyurethane laminate), cotton blends, and stretch knit; look for fully encasing zippers with anti-allergen barriers for protection, and breathable or cooling fabric if heat retention is a concern

Most encasements are machine washable on a gentle cycle with mild detergent and should be air-dried or tumble-dried on low per manufacturer instructions; avoid bleach and high heat to preserve waterproof laminates and zipper integrity

Encasements generally do not void mattress warranties, but you should check your mattress warranty terms; they minimally change feel if thin and breathable, and they do not significantly alter core support, though some fabrics can slightly reduce surface warmth or alter motion feel

Prices vary by material and features; budget encasements commonly start under $50 while midrange options are around the category average; consider certified waterproof and anti-allergen models for

A properly fitted, fully sealed encasement can block bed bugs from entering or escaping a mattress, but effectiveness depends on a complete seal, quality zipper, and treating other infested areas since encasements do not eliminate bugs already present in other furniture or the room
