SIHOO M102C Ergonomic Office Chair, big and tall, flip-up armrests, adjustable lumbar support, black

Big comfortable office chair I used at my desk every day. The seat goes from 45 to 54 cm, the mesh back has a lumbar pad you slide up and down, the headrest tilts and the armrests fold up flat so the chair slides right under a desk. It is already assembled and ready to sit on, nothing to build, you just take it away as it is. It came from September 2025 and barely got used, so it is nearly new.
