"This all-in-one outdoor seat and back cushion set delivers long-lasting comfort and reliable all-weather performance for patio, garden, balcony and backyard furniture. It adopts premium outdoor textile fabric with Grade 5 heavy water repellent capability and Grade 6 color fastness, which maintains vibrant color without fading within 1 to 2 years under continuous sun exposure. The seat cushion is filled with supportive 35D high density foam with 50-60 firmness to avoid sagging after long-hour sitting, while the matching back cushion uses fluffy PP cotton to provide soft lumbar relief. Refined craft details include half-cut fabric fixing ties to lock cushions firmly on chairs, full zipper removable outer covers for easy cleaning, plus 3mm thick cotton cord piping with reinforced fixed binding to create layered stereoscopic texture. Each complete set contains one seat cushion and one back cushion, equipped with standardized multi-layer vacuum compression packaging with tape reinforcement, barcode labeling and carton bulk packing to prevent extrusion and moisture damage during long-distance logistics.
