downluxe Outdoor Chair Cushions Set of 2 — Navy 18.5x16x3in Water-Resistant, High-Density Foam

downluxe Outdoor Chair Cushions Set of 2 are water-resistant, high-density foam seat cushions made to upgrade standard patio chairs with deep, supportive seating and secure tie fastenings.

These navy square-corner cushions (18.5" x 16" x 3") come as a pair and are designed for everyday outdoor use on dining and patio chairs. The polyester cover resists water, stains, and UV fading while the 3-inch high-density foam restores shape quickly after unpacking. Adjustable ties keep cushions in place, and simple spot cleaning keeps them looking fresh season after season.

Will these cushions fit my outdoor chairs?

They are sized to fit most standard dining and patio chairs with an 18.5" by 16" seating surface and 3" thickness. Because the design is square-cornered and moderate in thickness, they slide onto a wide range of frames without altering chair ergonomics.

• Actual dimensions: 18.5" (length) x 16" (width) x 3" (thickness).
• Square-corner profile for snug fit on flat seats.
• Adjustable side ties secure to chair backs or spindles.

How durable and weather-ready are the fabric and filling?

The outer cover is polyester engineered to resist water, stains, and UV fading, making it suitable for patios, balconies, and porches. The inner foam is high-density for long-lasting support and shape retention; cushions arrive compressed and usually rebound within 24–48 hours.

• Polyester cover resists sun fading and everyday stains.
• High-density 3" foam maintains support through repeated use.
• Vacuum-packed for shipping—tap and allow up to 48 hours to fully expand.

How do I keep them clean and looking new?

Spot cleaning with a damp cloth handles most spills; air drying in sunlight helps fluff the foam and refresh the cover. For heavier grime, gently hand wash the cover area and let it dry fully before reuse to prevent mildew.

• Spot clean with mild soap and a damp cloth; avoid machine washing covers.
• Hang to sun-dry to restore loft and remove moisture.
• Bring cushions indoors during prolonged rain to extend their life.

How do the ties and design keep cushions from slipping?

Each cushion has two adjustable straps that fasten around chair slats or frames, keeping the cushion in place during regular use. The combination of the square shape and strap placement reduces shifting even on frequent seating.

• Two adjustable side straps per cushion for secure attachment.
• Straps allow slight repositioning for different chair types.
• Low-profile design avoids interfering with chair stacking or storage.
