Full-Size Mattress Encasement

The LOCK-UP 83FULENC encasement fits a full-size mattress measuring 54 inches wide by 75 inches long. It is constructed from white stretch-knit fabric that stretches to accommodate a mattress up to 14 inches thick. Double-reinforced corners add durability at high-stress points. The cover fully encloses the mattress or box spring to block bed bugs, dust mites and common allergens.

Sleepers needing full allergen protection

This encasement suits anyone who wants a complete barrier against bed bugs, dust mites and allergy triggers on a full-size bed. It is not intended for twin, queen or king dimensions, so buyers with those mattress sizes should look elsewhere. The single white colour option may not match darker bedding aesthetics. Households that prefer a fitted protector rather than a full zippered enclosure will need a different style.

Simple stretch-on installation

The stretch-knit fabric pulls over the mattress like a fitted sheet and zips closed around all six sides. No tools or special skills are required. The main issue is forcing a mattress thicker than 14 inches into the cover, which can strain seams or prevent the zipper from closing fully. Machine wash in cold to medium water and tumble dry on low to medium heat; do not dry clean.
