Five Sided™ + Omniphase™ Mattress Protector by Malouf

The Five Sided Omniphase Mattress Protector combines three distinct technologies in one protector: OmniPhase® phase change material actively regulates temperature, TENCEL™ Lyocell wicks moisture away from the body, and the H2Pro® membrane delivers five-sided liquid-proof protection. Built for hot sleepers who also need complete allergen and liquid defense.

OmniPhase® Phase Change Material for Active Temperature Regulation

OmniPhase® is microencapsulated directly into the TENCEL™ fabric blend, so temperature regulation happens at the surface where the body makes contact. Phase change molecules absorb heat as they melt and release it as they solidify, cycling continuously to maintain the optimal sleep temperature in any climate.

This is active cooling, not passive breathability. The protector responds to the sleeper's temperature in real time, not just after heat has already built up.

TENCEL™ Lyocell Fiber for Moisture-Wicking Comfort

TENCEL™ Lyocell fiber is extracted from raw wood using a sustainable closed-loop process, producing a fabric that is more absorbent than cotton and softer than most synthetic alternatives. Moisture is drawn away from the skin quickly and dispersed through the fiber structure before it accumulates at the surface.

Night sweats and perspiration transfer away from the body continuously through the TENCEL™ layer. The sleep surface stays dry and cool without the sleeper needing to flip or reposition.

Five-Sided H2Pro® Coverage for All-Surface Protection

The laboratory-certified H2Pro® membrane extends across the top and all four sides of the mattress, closing every exposed surface to liquids, dust mites, and allergens. Standard top-only protectors leave the sides of the mattress unprotected where contamination accumulates over time.

Universal Fit® elastic secures the protector onto any mattress from 6 to 22 inches deep without bunching or corner lift. Adjustable base users and split king setups are both fully supported.
