The sled-shaped base is equipped with a scientific anti-tilt structure, allowing for a free swaying range of 15° forward tilt and 30° backward recline. The anti-slip felt pad provides a thoughtful protection for the floor. The heavy-duty frame with a spider-web-like structure is reinforced by triangular supports for long-lasting durability. The full lines support the arms, and the rubber wood chair legs combine texture and stability.
