"This 2-piece royal blue outdoor seat cushion set offers long-lasting weather resistance and steady ergonomic support for patio, garden, balcony and backyard chairs. Crafted with premium outdoor fabric rated Level 5 heavy water repellent and Grade 6 color fastness, it maintains vivid royal blue color without fading for 1 to 2 years under continuous sunlight. Each cushion is filled with 35D high-density foam at 50-60 firmness to resist sagging after long hours of sitting. Premium sewing details include half-split fabric fixing ties to stop sliding, fully zippered removable covers for easy cleaning, and 3mm thick cotton cord piping with reinforced binding to create rich three-dimensional texture. Each set includes two matching seat cushions. Every cushion undergoes vacuum compression with tape reinforcement, wrapped in PE bag and barcode-labeled mail bag; carton loading quantity can be adjusted to 4, 6 or 8 sets, fully preventing extrusion and moisture damage during shipping.
