Lumbar Support The office chair includes all the comfort and style you desire in a home office seat. The slim design in matte black/ dark charcoal gray color is a great combination with all desk styles. The size is perfect for every home office-substantial enough to offer comfort on those long calls, but not too large or industrial to overwhelm the room. The adjustable seat height allows you to find your sweet spot and reduces back stress. Padded arm rests and black base round out this great home office seat.
