u shaped chair cushions

Fill materials listed include memory foam, polyurethane foam, and polyester fiber. Cover fabrics shown include non-woven fabric and velvet; the textile material is described as 100% polyester.

Available shapes include rectangular and half‑circle styles, plus U-shaped ergonomic cushions that feature a rear cut-out for coccyx relief.

They use anti-slip features such as non-slip rubber bottoms or skid‑proof backing. Some models also include ties or straps (or upper‑cushion fastenings) to secure the cushion to the seat.

Many cushions feature a zippered, removable mesh cover that is machine washable. Velvet‑style covers are also described as machine washable; care instructions include washing cold and tumble drying without heat.

Several cushions include a full three‑year warranty and a satisfaction guarantee; one description also mentions a free replacement if the pillow goes flat.
