Flip-up armrests solve a specific problem: a chair with fixed arms will not push under a desk, so it sits proud of the desk edge and blocks the walkway. Fold these upward and the chair tucks completely away; fold them down and they support the arms in the ordinary manner. That single hinge is the difference between a chair that fits a small workspace and one that does not. The seat cushion is thickened, built from high-density sponge and wrapped in premium PU leather, so the padding holds depth under daily use rather than compressing to the board within months, and the leather wipes down instead of absorbing marks. The backrest is shaped ergonomically to support the spine, and a rocking tension control lets the recline be set tight for upright work or loose for leaning back, so the chair can be tuned to body weight rather than fighting it. Height is set on a lifting lever under the seat, adjustable through a range that puts the chair at 41 to 44 in overall. Underneath, a reinforced 5-claw metal base spreads the load reliably and smooth rolling casters move the chair around a workspace without dragging. Rated capacity is 300 lbs, the assembled chair measures 26 by 22.5 in across and weighs 31 lbs, and it suits home and office use equally. Assembly is needed.
