How to Install: This swing seat cover replacement in particular is made for the seats that have three bars to slide it on. Please note that you have to dismantle seat to slide on through the holes (diameter:2.36"/6cm) to the bars, and reassemble. It's very easy to install. Sturdy Design: While you are sitting on it, the cover might sag a little bit in the middle, which is designated to protect it from breaking. But if you put two or three cushions/throw pillows on it, it will be more comfortable. Material: It's not padded, it's a fabric cover. Made of high-quality 600D oxford fabric with coated waterproof fabric and high-density stitched seams for durability, which can help extend the life of your swing seat. Protection: This repacement cover can protect your swing chairs against sun, rain, wind, frost, snow, dirt, and residue, etc. Also, it is washable and reusable. You can store it in the included bag when not in use. NOTE: Before you buy, please be sure to measure your patio swing chair, as our swing chair covers are not universal in size.
