Aoxun Outdoor Replacement Cushions for 4-Seater Patio Sofa — 4-Piece Grey Set, 4" High-Density Seat & Plush Back

Aoxun's 4-piece grey outdoor replacement cushions are a full patio cushion set—two 4" seat pads and two plush back cushions—designed to refresh a 4-seater outdoor sofa with durable, weather-resistant comfort.

Replace flattened or faded cushions with a coordinated set built for outdoor use. This Aoxun cushion pack includes two seat cushions (22.5" x 20.5" x 4") and two back cushions (21.6" x 18.5" x 8") sized for most four-seater patio sofas. Each piece arrives vacuum-packed and regains its full 4" thickness within 48–72 hours; covers are heavy-duty polyester treated to resist UV, moisture, and ordinary staining.

Will these cushions fit my existing patio sofa?

Measure before you order to ensure a snug fit; the set is tailored for many standard 4-seater outdoor sofas. Seat and back dimensions are specified so you can compare to your current cushions or frames. The flexible button straps and non-slip silicone dots help secure the cushions to irregular surfaces.

• Seat dimensions: 22.5" x 20.5" x 4"
• Back dimensions: 21.6" x 18.5" x 8"
• Straps and silicone dots keep cushions aligned on frames
• Vacuum-packed — expands to shape within 48–72 hours

How comfortable and supportive are the cushions for everyday use?

The seat pads use 4" 24D high-density foam to deliver steady support that resists sagging over time, while the back cushions are filled with fluffy PP cotton for a softer, cloud-like feel. This combination balances firm seating with plush back support for long chats, lounging, or short naps outdoors. The materials are chosen to maintain shape under regular outdoor use.

• 4" 24D high-density foam in seat cushions for lasting support
• PP cotton fill in back cushions for softness and rebound
• Designed to retain shape and resist collapse under daily use

Are these cushions weatherproof and easy to maintain?

The Aoxun cushions are covered in heavy-duty polyester fabricated to resist fading, water exposure, and UV damage—suitable for decks, patios, poolside seating, and garden lounges. The covers have reinforced zippers and are machine washable, simplifying seasonal cleaning. Note that polyester is water-resistant rather than fully waterproof; quick drying and occasional care keep them performing well.

• Durable polyester fabric resists fading and UV damage
• Water-resistant finish for light moisture and splashes
• Reinforced zipper covers are machine washable

How do the cushions stay in place in wind or on smooth frames?

The set includes olive-shaped button straps that wrap around frame elements and a non-slip silicone dot pattern on the underside of seat cushions to reduce shifting. Combined, these features minimize sliding during use and help keep cushions locked to outdoor furniture even on breezy days. They’re suitable for woven, metal, and hard-surface frames with typical patio geometries.

• Olive-shaped button straps secure cushions to the furniture frame
• Non-slip silicone dot pattern reduces movement on smooth seats
• Effective for wicker, metal, and rattan-style outdoor sofas

It’s ideal for anyone replacing worn cushions, updating outdoor decor with a neutral grey tone, or outfitting rental properties and seasonal outdoor lounges.
