Summsun Outdoor Chair Cushions Set of 4 — Navy 18.5 x 16 x 2 Inch Water-Resistant Seat Pads with Ties and Hidden Zipper

Summsun Outdoor Chair Cushions Set of 4 are water-resistant, fade-resistant 18.5 x 16 x 2-inch seat pads designed to refresh patio and dining chairs with cushioned support and easy-care covers.

These navy chair cushions are built for outdoor living: a resilient 28D foam core wrapped in 250GSM polyester with a double waterproof coating, adjustable ties to lock each pad in place, and a concealed zipper for quick cleaning. The construction balances comfortable give with firm support, while the treated fabric resists sun fading and shed moisture so the cushions stay usable season after season.

How do these cushions improve sitting comfort outdoors?

The 28D high-resilience foam core offers consistent pushback, reducing pressure points when you sit for longer periods. The 2-inch thickness is engineered to cushion hips and lower back without making seats unstable.

• 28D foam core for balanced support and elasticity
• 2-inch thickness for everyday patio use
• Sized 18.5 x 16 inches to fit most dining and lawn chairs

Will these cushions survive rain, sun, and frequent use?

The outer fabric uses a double-layer waterproof coating that helps stop water from penetrating to the foam, keeping the interior dry and cleaner between washes. An additional fade-resistant treatment helps colors stay vivid for up to three years under normal outdoor exposure.

• 250GSM polyester with two-layer waterproof coating
• Fade-resistant finish to protect color from UV exposure
• Durable stitching and materials suited for patios, decks, and balconies

How easy are these cushions to secure and maintain?

Each cushion includes two adjustable ties that fasten to chair backs to prevent slipping while you sit or move. The hidden zipper lets you remove covers for machine washing, so routine cleaning is simple and the cushions keep a neat appearance.

• Two adjustable ties per cushion for a snug fit
• Concealed zipper for a clean look and removable covers
• Machine-washable covers for straightforward maintenance

What chairs and settings are these cushions best suited for?

Their 18.5 x 16-inch footprint and moderate 2-inch thickness make these pads a versatile replacement for many dining chairs, rattan seats, and lawn furniture. You can use one set to outfit a small patio or mix and match multiples for larger seating arrangements.

• Fits dining chairs, rattan and wicker seating, poolside loungers, and balcony furniture
• Available in packs (sets of 2/4/6) to match multi-seat setups
• Neutral navy color complements a wide range of outdoor palettes
