BRING NEW LIFE TO YOUR OLD MATTRESSESAll mattress covers are constructed of heavy-duty healthcare grade fabrics. Our vinyl fabrics utilize triple-ply construction to with stand physical and environmental abuse. The SOFlux OXŸ nylon is a very tough urethane coated fabric designed for added comfort and longer cover life. SOFlux OXŸ also provides a more comfortable sleeping surface by reducing body heat build-up and eliminating the plastic feel associated with vinyl. All covers are zippered at one end and down each side for easy installation.Quantity Discount is available.
