Arden Selections Outdoor Midback Chair Cushion 18 x 16.5 Clark Blue — UV-Resistant, PFAS-Free Water Repellent

The Arden Selections Outdoor Midback Chair Cushion in Clark Blue is a weather-ready, midback cushion sized for standard dining and bistro chairs, combining recycled fill, UV-resistant fabric, and secure ties for comfortable outdoor seating.

This midback chair cushion is designed to refresh outdoor seating with a durable Clark Blue polyester cover and supportive partially recycled fiber fill. Sized at 18 inches wide with a 16.5-inch seat depth and a 20-inch back, it works with most dining, stacking, and bistro chairs. The fabric includes enhanced UV protection to reduce fading, and the cushion carries a 1-year limited fabric warranty and a PFAS-free C0 water treatment for safer outdoor use.

Will this cushion fit my dining or bistro chair?

Yes — the cushion is tailored to fit most standard dining, stacking, and bistro chairs thanks to its common midback dimensions. The two-piece design separates seat and back sections while remaining attached for easy placement.

• Seat dimensions: 18 in W x 16.5 in L; back: 18 in W x 20 in L (total length 36.5 in)
• 3.5 in thickness for cushioned support without bulk
• Four sets of ties secure cushion to chair frame
• Works with metal, wood, and many plastic outdoor chairs

How does this cushion stand up to sun, spills, and outdoor use?

The Clark Blue cover is 100% polyester treated with UV protection to resist fading from sunlight and a C0 PFAS-free finish to provide water repellency without long-chain fluorochemicals. It’s made for easy outdoor maintenance and daily exposure.

• Enhanced UV treatment slows color loss from sun exposure
• PFAS-free C0 water treatment repels light moisture and reduces absorption
• Spot-cleanable with soap and water for simple upkeep
• 1-year limited fabric warranty for manufacturing defects

How comfortable and durable is the fill material?

The cushion uses a partially recycled polyester fiber fill formulated to retain shape and provide soft, consistent support for casual outdoor seating. The fill balances resilience and comfort so the cushion keeps its profile without becoming too firm.

• Partially recycled polyester fiber fill for sustainable cushioning
• Designed to keep loft and shape with repeated use
• 3.5 in thickness for a balance of softness and support
• Two-piece midback layout distributes support across seat and back

What practical features make installation and care easy?

Installation is quick thanks to four sets of ties that secure the cushion to the chair and prevent slipping. Routine cleaning is straightforward—mild soap and water are enough for most spills—so you can keep the Clark Blue cushion looking fresh with minimal effort.

• Four tie pairs keep cushion firmly attached to the chair
• Simple cleaning: soap, water, and a soft brush or cloth
• Lightweight, easy to move between seating areas
• Back and seat remain connected for correct alignment
