These chair cushion pads provide comfortable support for extended sitting whether you're reading, watching television, or dining. Each cushion measures 17.72 by 17.72 by 3.15 inches and features a polyester fiber outer layer with pearl cotton filling that offers breathable comfort while relieving pressure on your hips and lower back. The cushions are constructed with fine stitching to maintain their shape over time. Two extra-thick ties on each cushion secure it firmly to your chair, preventing unwanted movement during use. The set of four cushions works well on dining chairs, office chairs, patio furniture, rocking chairs, kitchen seating, or benches. They are particularly helpful for people who sit for long periods, including office workers and drivers, providing relief from tailbone discomfort and back strain. This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. The cushions are available in multiple colors and each weighs approximately 0.44 pounds. Care instructions should be followed to maintain the fabric and filling quality.
