Premium material and comfort Crafted from 220GSM faux linen net cloth fabric and 30D high-resilience foam, these chair pads provide strong support with excellent resilience. The breathable surface and ergonomic design help cushion the tailbone and may relieve sitting-related discomfort. The foam bounces back after long use for lasting comfort. Non-slip design Two-layer non-slip system keeps pads in place: non-slip backing dots plus up to 12-inch attached ties secure the cushions to most chairs and surfaces, preventing shifting during use. Size and compatibility D-shaped chair pads measure 17"L x 16"W x 2"H. They fit a wide range of chairs, not only dining and kitchen chairs but also suitable for office, bedroom, and other indoor or outdoor settings. Durable construction Soft, durable fabric with sustainability features and overlock stitching minimizes fraying and tearing, keeping the cushions intact longer. The material is gentle on furniture surfaces and maintains a neat appearance over time. Use scenarios - Dining room or kitchen: add comfort during meals and reduce tailbone pressure. - Office or study: support long work sessions with stable, comfortable seating. - Living areas and outdoors: suitable for chairs on patios, balconies, or bedrooms for everyday use.
