Summsun Outdoor Chair Cushions Set of 4 — Black 18.5 x 16 x 2 in Waterproof, Fade-Resistant Patio Seat Pads

Summsun outdoor chair cushions set of 4 are 18.5" x 16" x 2" waterproof, fade-resistant seat pads with ties and hidden zippers designed to refresh patio and dining chairs.

These chair cushions combine weather-ready outer fabric with resilient inner foam to offer comfortable seating on patios, balconies, poolside lounges, and dining sets. Built from 250GSM polyester with a double-layer waterproof coating and 28D high-resilience foam, the cushions are sized to fit most standard outdoor chairs and include adjustable ties and a concealed zipper for a sleek, practical finish.

How do these cushions hold up to rain and spills?

The cushions use a two-layer waterproof coating on durable polyester to keep most moisture from reaching the foam core, helping the pads dry faster and resist water damage in outdoor settings. While they provide strong water resistance, they are not meant to be left submerged indefinitely—prompt drying after heavy exposure preserves performance.

• 250GSM polyester shell with double-layer waterproof coating
• Hidden zipper for quick removal and drying of covers
• Designed to block surface water and speed evaporation

Will these cushions resist sun fading and maintain their color?

Summsun cushions are treated with fade-resistant technology to help colors stay vivid through regular outdoor exposure. The high-quality coated polyester is formulated to withstand UV exposure and typical weather conditions for extended visual durability.

• Advanced fade-resistant treatment for longer-lasting color
• Fabric formulated to resist sun and rain-related fading
• Color stability expected under normal outdoor use for multiple seasons

Are these cushions comfortable and easy to secure to chairs?

The 28D high-resilience foam core offers springy support and retains shape after sitting, while the 2" thickness balances comfort with a low-profile look. Each cushion includes two adjustable straps to keep pads from slipping and a hidden zipper so covers can be removed for machine washing.
