Summsun Outdoor Chair Cushions 19 x 19 in Navy — 4-Piece Set, Faux Linen, Water-Resistant Covers

Summsun Outdoor Chair Cushions are a four-piece 19 x 19 inch patio cushion set with faux-linen covers, high-density foam seat cores, shredded-foam backrests, and weather-resistant removable covers for long-lasting outdoor comfort.

If you want to refresh your patio seating with durable, comfortable cushions that resist light rain and fading, this Summsun set was designed for that exact purpose. Each set includes two seat cushions with firm 28D high-density foam and two overstuffed back cushions filled with shredded foam and PP cotton, all wrapped in a water-repellent faux linen fabric with an inner water-resistant membrane.

How supportive and comfortable are these cushions?

The seat cushions use a 28D high-density foam core that delivers firm, resilient support that resists sagging, while the back cushions are overfilled with shredded foam blended with PP cotton for a contouring, cloud-like feel. Together they recreate the supportive ergonomics of new patio furniture without replacing frames.

• Seat core: 28D high-density foam for long-term firmness
• Back fill: shredded foam + PP cotton for adaptive comfort
• Depth and loft engineered for standard 19 x 19 chairs
• Hidden zipper for neat appearance and easy refill

Will these cushions stand up to outdoor use and occasional rain?

Yes — the covers are treated with an external water-repellent finish so light moisture beads up and rolls away, and an internal laminated water-resistant membrane blocks water penetration during light to moderate showers. For best longevity, bring cushions indoors during heavy rain or storms.

• Outer layer: faux linen with water-repellent coating
• Inner layer: water-resistant membrane to prevent soak-through
• Anti-UV treatment to slow color fading from sun exposure
• Care tip: store under cover or inside in bad weather

How are the cushions kept in place on different chairs?

Summsun designed the seat cushions with two sets of attached ties to anchor them to chair frames and a non-slip fabric on the bottom to increase friction. The back cushions are tie-free for flexible placement and a cleaner look.

• Dual ties on seats for secure attachment
• Anti-slip bottom fabric reduces sliding on smooth seats
• Back cushions: tie-free for versatile positioning
• Stitching and hidden zipper enhance durability and appearance

How easy are these cushions to clean and install?

Cushion covers unzip for machine washing on a gentle, cold cycle; you can tumble dry low or air dry. They ship vacuum-compressed — inserting the foam and allowing 24–72 hours for full expansion is all that’s needed to start using them.

• Vacuum-compressed for compact shipping; expands in 24–72 hours
• Removable covers with hidden zippers for laundering convenience
• Machine wash gentle, cold; tumble dry low or air dry
• Do not iron; routine care preserves water-repellent finish
