Standard protectors cover the top of the mattress, leaving every exposed side unprotected. The Malouf Five-Sided Waterproof Mattress Protector extends the laboratory-certified H2Pro® membrane across all five exposed surfaces, closing every entry point for liquids, dust mites, allergens, and viruses. It is a partner product with the American Lung Association's Lung Force campaign.

Five-Sided Coverage for Complete Mattress Defense

Every night, the body sheds skin flakes and loses fluid through perspiration. Standard top-only protectors leave the sides of the mattress exposed to exactly these sources of contamination. The Five Sided™ extends H2Pro® coverage across the top and all four sides, sealing every exposed surface.

This is the structural difference that separates this protector from every single-surface model. Dust mites, allergens, and liquids have no uncovered entry point to exploit.

Asthma Prevention and American Lung Association Partnership

Five-sided mattress protection actively helps prevent the development of asthma by blocking allergen accumulation inside the mattress. This protector is a certified partner product of the American Lung Association's Lung Force campaign, a distinction no single-sided protector in this range carries.

Dust mite waste is one of the most potent indoor allergens. The H2Pro® membrane's microscopic pores block dust mites, bacteria, and viruses before they penetrate any surface of the mattress.

Ultra-Thin, Noiseless Construction for Sensitive Sleepers

The smooth hypoallergenic polyester surface is PVC and phthalate-free, making it safe for chemically sensitive sleepers and children. The ultra-thin design lies flat under a fitted sheet without altering mattress firmness or feel.

Light sleepers who wake at every crinkle get a protector that operates in complete silence. The breathable weave prevents heat buildup, so there is no thermal disruption to sleep either.

Five-Sided Coverage Geometry
Full Wrap Protection

Five-Sided Coverage Geometry

No gaps, no exposed edges

The H2Pro® membrane wraps continuously from the top surface down all four sides of the mattress skirt, leaving no gap between the covered top and the floor-facing edges. This geometry closes the contamination pathways that top-only protectors cannot address structurally.

Microscopic Barrier Science

H2Pro® Microscopic Pore Blocking

Blocks contaminants, welcomes airflow

H2Pro® pores are sized below the diameter of liquid molecules, dust mite bodies, virus particles, and bacteria. Air molecules pass through freely in both directions, while every biological contaminant larger than an air molecule is physically blocked from penetrating any of the five covered surfaces.
