Zonamat Outdoor Chair Cushions - Deep-Seat Waterproof Patio Set (24x24x5.75) with UV-Resistant, High-Density Foam

Zonamat Outdoor Chair Cushions are a waterproof, UV-resistant deep-seat patio cushion set built for lasting comfort and weather protection.

These cushions combine a deep-seat profile with weatherproof construction and upgraded filling designed for outdoor living. The set includes one 24" x 24" x 5.75" seat cushion and one 25" x 22.5" backrest pillow sized to fit most deep-seat chairs and outdoor couches. Zoned for durability, the covers pair Oxford polyester with a TPU inner lining and yarn-dyed fabric to resist moisture, fading, and daily wear.

Will these cushions keep water and spills out?

Yes — the cushions are engineered for outdoor exposure using a double-sided waterproof approach. The outer shell is water-resistant Oxford polyester and an internal TPU laminate prevents liquids from reaching the foam core.

• TPU-laminated inner lining for reliable moisture barrier
• Oxford polyester shell sheds light rain and splashes
• Hidden zipper for quick cover care without exposing foam

How do they stand up to sun and fading over time?

These cushions use yarn-dyed fabric with UV-protective properties to retain color longer under regular sun exposure. Yarn-dyeing embeds color in the fibers, improving colorfastness compared with surface-printed textiles.

• Yarn-dyed outdoor fabric for better long-term color retention
• UV-resistant treatment to reduce sun bleaching
• Reinforced piping resists fray under repeated use

Are they comfortable and will the filling keep its shape?

The seat cushion contains high-density foam for firm, supportive seating that resists quick flattening, while the back pillow blends memory foam, cotton, and polyester for contouring lumbar support. This pairing provides both structural support and plush comfort for relaxed outdoor seating.

• High-density seat foam for lasting support
• Memory foam/cotton/poly blend back pillow for gentle contouring
• Thickness suited for deep-seat chairs and loungers

How do these fit and stay in place on my patio furniture?

The set is sized to match most standard deep-seat patio chairs, and includes adjustable ties to secure cushions against slipping. A concealed zipper and reinforced stitching make the design tidy and durable for everyday outdoor use.

• Seat: 24" W x 24" D x 5.75" T; Back: 25" W x 22.5" H
• Adjustable ties prevent shifting in windy or active settings
• Hidden zipper maintains a sleek appearance and allows removal for cleaning
