Thick, deformable chair cushions provide soft, plush comfort with a 3 cm thick memory foam filling that resists crushing and offers good elasticity on hard surfaces. The U-shaped design is suited for dining chairs, delivering steady support during meals. Strap system ensures a secure fit. The cushions include a long-lasting tape that can be attached to any area of the chair. The straps allow many bundling methods and can be fastened to chair legs or the backrest to prevent movement or slipping. Underside stability is built in. The underside uses D-shaped straps with heat-resistant plastic, providing many small contact points to keep the cushion from sliding on smooth surfaces and to help maintain a stable seating experience during meals. Removable, easy-to-clean cover. The cushion cover features a zip for easy removal, and an inner lining helps secure the cotton filling, enabling straightforward removal and reassembly of the cover. Use scenarios - Everyday dining on dining room or kitchen chairs, especially on hard or uneven surfaces where extra cushioning improves comfort. - Chairs with smooth or slippery bases benefit from the strap system to prevent movement during use. - Quick cleanup after meals or spills: remove the cover for washing and reattach with the secure inner lining in place.
