Qirroboni Outdoor Chair Cushion Set Of 4, Waterproof Square, Charcoal Grey SIZE AND PACKAGE: The size of the outdoor chair cushions is 19" x 19" x 3" and fits most standard-sized chairs. Please measure the size of the chair before purchasing. As the outdoor cushions are vacuum-packed, you can press and tap them for a while after opening the vacuum bag, and they will regain their fluffiness within 24-48 hours. PREMIUM WATERPROOF ABILITY: Our Qirroboni cushions utilize multiple methods to enhance the waterproof ability of each cushion. They are fully covered with waterproof, stain-proof, and UV-resistant high-density fabrics. Additionally, two attached ties prevent chairs and cushions from shifting or sliding, ensuring a secure fastening to the chairs. STABLE AND FLEXIBLE: Featuring luxurious padding support with a 3-inch thick, high-quality sponge, our cushions are super soft, comfortable, and possess excellent elasticity, providing long-lasting recovery ability. These cushions are designed to alleviate pressure points in your lower body caused by hard seating surfaces. By cradling your bottom, they help reduce pain in your lower back, hips, and sciatic nerve. EASY TO CLEAN: Cleaning the patio cushions is a breeze. Simply spot clean them with a damp cloth and allow them to sun-dry. Sun exposure will not only help them dry faster but also enhance their fluffiness and resilience. If you have any questions or suggestions, please feel free to reach out to us at your convenience. We are here to assist you and value your feedback. VARIOUS OUTDOOR USES: Our outdoor seat cushions come in a range of colors and patterns, adding a vibrant touch to your home and patio. They are versatile and suitable for patio chairs, garden chairs, and pool chairs. In fact, they can also be used as comfortable floor cushions.
