Summsun Outdoor Chair Cushions Set of 4 — Beige 18.5 x 16 x 2 in Water-Resistant, Machine-Washable

Summsun outdoor chair cushions set of 4 are water-resistant, 18.5 x 16 x 2 inch seat pads with ties and hidden zippers designed to replace and upgrade standard patio chairs.

These beige patio chair cushions combine a resilient 28D foam core with a 250GSM polyester shell finished in a double-layer waterproof coating, creating a reliable option for backyard seating, dining chairs, rattan furniture and poolside loungers. Designed to fit most standard outdoor chairs, the covers unzip for easy washing and the adjustable ties hold each cushion securely in place.

How well do these cushions stand up to wet weather and sun exposure?

The cushions use a double-layer waterproof coating to repel moisture and protect the foam core from light rain and splashes. A fade-resistant treatment helps maintain color vibrancy even after repeated outdoor use, extending the cushion’s visual life.

• 250GSM polyester fabric with double-layer waterproof coating
• Protects inner 28D high resilience foam from moisture
• Fade-resistant finish keeps beige tones from dulling for up to three years
• Slight water resistance; avoid prolonged submersion

Will these cushions fit my patio chairs and stay in place?

Each cushion measures 18.5 x 16 x 2 inches, a common size for dining and patio seats, making them suitable for most standard outdoor chairs. Two adjustable ties secure the cushion to the chair frame and a non-slip design helps reduce shifting during use.

• Standard 18.5" x 16" footprint fits most chairs
• 2" thickness for moderate comfort and support
• Two adjustable straps and ties for a secure fit
• Hidden zipper allows cover removal without displacing ties

How comfortable and durable are these seat pads for everyday use?

Filled with 28D high-resilience foam, the pads deliver responsive support for everyday sitting without flattening quickly. The foam’s elasticity paired with a robust outer shell balances cushioning and longevity for family gatherings and frequent outdoor use.

• 28D high resilience foam provides steady bounce-back
• 2" thickness offers support without bulkiness
• Durable polyester shell resists wear from regular use
• Machine-washable covers for low-effort maintenance

How easy is cleaning and maintaining these cushions?

The hidden zipper makes it simple to remove the covers for washing; the fabric tolerates machine cleaning so routine upkeep is straightforward. Because the outer material is treated for water resistance and fading, spot cleaning and periodic laundering will keep them looking fresh longer.

• Hidden zipper enables quick cover removal
• Covers are machine washable to simplify maintenance
• Water-resistant coating reduces staining and moisture buildup
• Air-dry covers to preserve coating and shape
