AAAAAcessories Outdoor Chair Cushion Set — Single Deep Seat 25.5x25.5x5 + 25.5x13.5 in, waterproof UV-resistant polyester

AAAAAcessories Outdoor Chair Cushion (25.5 x 25.5 x 5 + 13.5 in) is a single deep-seat set crafted to upgrade outdoor seating comfort and durability with waterproof polyester cover, supportive foam, and secure ties.

This single-seat cushion set from AAAAAcessories combines a roomy 25.5 x 25.5 x 5-inch seat cushion with a 25.5 x 13.5-inch back pillow to refresh a chair, loveseat section, or occasional sofa. Designed for outdoor environments, the cushion uses a UV-resistant, breathable polyester cover and a resilient polyurethane core so you get both cushiony support and weather-ready performance. The cover’s hidden zipper makes cleaning or replacing the insert straightforward, while non-slip ties and piped edges keep the look tidy and the cushion stable during use.

How does this cushion perform outdoors?

The cover is 100% polyester treated to resist fading from sunlight and to shed moisture for everyday outdoor use. The fabric breathes to reduce trapped heat, and the zipper is hidden to prevent water ingress and preserve a neat appearance.

• UV- and fade-resistant polyester exterior
• Breathable weave that reduces heat buildup
• Hidden zippered cover for easier cleaning and replacement

What level of comfort and support can I expect?

The seat cushion contains 100% polyurethane foam designed for a deep, supportive sit that relieves pressure points while holding shape over many uses. The included back pillow is polyester-filled for softer back support and quick recovery after compression.

• Deep 5" seat thickness for cushioned support
• Polyurethane foam core for resilient seating
• Polyester pillow for comfortable lumbar or back support

Will it fit my existing furniture and how do I install it?

The seat measures 25.5 x 25.5 inches with a 5-inch thickness and the back is 25.5 x 13.5 inches. Measure your chair before purchasing — if your seat differs by more than 0.5 inches, the fit may be too tight or loose. Installation is simple: align the cushion, secure ties to chair frame, and allow compressed foam up to 24 hours to fully expand.

• Seat: 25.5" x 25.5" x 5" — Back: 25.5" x 13.5"
• Non-slip ties attach to chair frame for stability
• Cushion ships compressed; allow 24 hours to recover shape

How should I care for and maintain the cushion?

The hidden zippered cover can be removed for spot cleaning or gentle machine washing per care instructions, helping the cushion stay fresh without replacing the entire unit. Routine shaking and airing will extend fabric life and preserve loft.

• Remove cover via hidden zipper for cleaning
• Spot clean or follow gentle wash instructions on label
• Air cushions and fluff regularly to maintain loft
