HARBOREST Outdoor Chair Cushions Set of 4 — Navy 18.5"x16"x3" Water-Resistant, Tied Square-Corner Seat Pads

HARBOREST outdoor chair cushions are a four-piece set of water-resistant, square-corner seat pads (18.5" x 16" x 3") built to keep patio chairs comfortable, secure, and looking tidy.

These navy HARBOREST cushions are sized for most standard patio chairs and ship as two cushions in each of two vacuum-sealed bags for compact delivery. The covers use a durable polyester blend engineered to shed water, resist stains and slow UV fading, while the interior foam delivers supportive resilience and rebounds after unpacking. Attached ties help anchor each cushion to the chair frame so cushions stay put during normal outdoor use.

How will these cushions withstand outdoor conditions?

The HARBOREST cushions combine water-resistant polyester and quick-drying foam to handle sun-exposed porches, screened patios, and covered decks. They are designed to resist light moisture and common outdoor staining while being simple to wipe clean when needed.

• Water-resistant polyester cover that sheds light rain and splashes
• Stain-resistant finish for easier spot-cleaning
• UV-resistant treatment to slow color fading from sunlight
• Recommended for covered or semi-protected outdoor locations

Will the cushions stay secure on my chairs?

Each cushion includes two sewn-in ties to fasten to chair slats or frames, reducing sliding and shifting while you sit. The square-corner shape fits neatly against straight-edged seats for an aligned, finished look.

• Two attached corner ties per cushion for stable attachment
• Square-corner design fits standard chair seats without overhang
• Measures 18.5" x 16" x 3" — check chair dimensions before ordering
• Sold as a set of four cushions (packaged as two cushions per bag)

How comfortable and durable is the inner foam?

Inside each cushion is a high-resilience foam that offers consistent support and regains its shape after being compressed. Because cushions ship vacuum-packed, allow 24–48 hours for the foam to fully decompress and return to its intended thickness.

• High-resilience foam core for lasting support and recovery
• Vacuum-sealed packaging to reduce shipping size and protect the product
• Full shape typically restored within 24–48 hours after opening
• Suitable for repeated everyday seating on outdoor furniture

How do I clean and maintain these patio seat cushions?

Maintenance is straightforward: most dirt and spills come off with a damp cloth and mild soap. If cushions get flattened, a period in the sun or a brief tumble-dry on low (if the care label permits) can help restore loft.

• Spot-clean with a damp cloth and mild soapy water
• Air-dry fully before storing to prevent mildew
• Fluff or sun-dry to recover cushion thickness after storage
• Store indoors or in a dry, ventilated container during prolonged inclement weather

Who is this for: The HARBOREST 4-piece cushion set is ideal for homeowners and renters who want an easy, affordable upgrade to their outdoor seating. Choose these cushions if you need compact-packaged, quick-to-deploy seat pads that combine supportive foam with a water-resistant polyester shell — especially suited for patio dining chairs, deck seating, garden benches with matching seat dimensions, or any straight-edged outdoor chair approximately 18.5" by 16".
