【All-Weather Fabric】Crafted from premium polyester with TPU waterproof coating, our patio furniture seat cushions feature excellent UV protection. The fabric can withstand long hours of direct sunlight without fading, and the water-repellent surface keeps the inner foam dry even on rainy days. This breathable woven material stays comfortable all year round for outdoor patio use. 【High Resilience Filling】We use whole-piece 35D high density foam as filler for these square chair pads. It evenly spreads hip pressure and alleviates soreness from prolonged sitting. The cushion boasts instant rebound and anti-sag performance, so it will not flatten or deform after months of frequent use. 【Practical Built-in Structure】Equipped with sturdy binding straps, this outdoor chair cushion stays fixed firmly on wicker and dining chairs and will not shift when you get up and sit down. It adopts an invisible zipper design for a removable cover, and reinforced piped edges effectively prevent fraying. An extra portable side handle makes moving and storage simple. 【Low-Maintenance Care】The zippered outer cover of this washable patio seat pad supports machine washing. Daily dust can be wiped clean with a damp cloth. The colorfast fabric will not shrink or discolor after repeated cleaning, so you can keep your outdoor cushion fresh with little effort. 【Wide Scenario Use】These square replacement chair cushions come in multiple solid colors and standard sizes to fit most rattan seats, garden benches and kitchen stools. The indoor outdoor universal seat pads are ideal for backyards, balconies, poolside areas, home dining rooms and bistro restaurants.
