Keep your cushions fresher, longer with Black Cushion Underlining—a lightweight, vinyl-coated polyester fabric designed for the underside of cushions, seats, and upholstery in your home, boat, RV, or patio.

Its breathable construction allows air to circulate and moisture to escape, helping cushion foam resist rot and mildew and extending the life of your cushions. The light vinyl coating helps reduce slipping (though it is not a non-slip fabric) while still allowing for water drainage—making it ideal for both indoor and outdoor use.

For cushions that can’t be flipped, using this fabric on the bottom side provides a cost-effective way to improve airflow. The result? Cushions that don’t trap air or feel like balloons when you sit down—and that bounce back to shape more quickly after use.

Cleaning Instructions:

• Prepare cleaning solution using 1 tablespoon liquid dish detergent and 2 tablespoons household bleach in 1 gallon of water. Clean fabric with a sponge or soft cloth dipped in solution.
• Rinse thoroughly with clear water and air dry.
• Avoid direct contact with oil-based products which may cause accelerated aging of fabric. If direct contact occurs, clean promptly.
• Regular maintenance of your fabric will help extend the life. Clean 1-2 times a year when in moderate use (more frequently when used heavily).
