Upholstery: Most versions use Bonded Leather or PU (Faux) Leather. Genuine leather options exist but are significantly more expensive.

Frame & Base: Polished Chrome-plated steel or aluminum. The "ribbed" look is created by heat-embossing the material over the frame.

Armrests: Fixed, polished chrome "loop" arms (often includes removable zippered covers in the same leather material).

Base: 5-star swivel base with dual-wheel hooded casters.

Mechanism: Tilt-lock mechanism that allows the chair to rock or be locked in the upright position.

Adjustments: Pneumatic gas lift for height adjustment and a tilt-tension knob to adjust the resistance of the recline.

Swivel: Full 360° rotation.

Lumbar Support: Built-in "passive" lumbar support due to the ergonomic curve of the frame.
