Smooth office chair cushion: Keeps the chair in place and allows chair casters to roll smoothly and quietly, reducing fatigue in your legs and back while you work. Sturdy and durable: Made of 1.5 mm thick PVC material with impact resistance and heat resistance. It is transparent, unbreakable, and absorbs noise, and will not sink, scratch or fade. Protects hard floors: Our floor protection pads guard hard floors from daily scratches and damage caused by office chairs, dining tables or other furniture. Suitable for laminate, marble, ceramic tile, parquet floors, concrete, and other hard surfaces; it can also be used on carpets. Easy to clean: The transparent mat can be used on the floor, dining table, and kids' painting mats. For stains and spills, wipe with a damp cloth and dry. Use scenarios: Ideal for a home or office setting with wood or laminate floors under a desk chair; in conference rooms with rolling chairs on tile or concrete; and in dining areas or kids' activity spaces where furniture movement occurs.
