Sihoo Ergonomic High-Back Mesh Office Chair, Black - 3D Headrest, Dynamic Lumbar & 130° Recline

Bringing structure and style to a home study or a dedicated home office, the Sihoo Ergonomic High-Back Mesh Office Chair is designed for focused work environments where considered support and room aesthetics both matter. The all-black finish suits contemporary interiors, and the open-weave mesh on both the seat and backrest keeps the chair looking light rather than bulky. The high backrest rises 50.3-56.4 cm, tapering from 66.5 cm at its widest mid-section to 54.1 cm across the upper section, giving the chair a well-proportioned silhouette from any angle. For home-office use, the chair's three support zones are particularly practical. The 3D mechanical headrest (32.5 cm wide, 15.5 cm tall) can be repositioned for neck support when working at a screen, or shifted to a reclined angle during a reading break. The self-adaptive dynamic lumbar support is built into the backrest's flexible mesh structure and responds to the body's natural movement without the need to pause and readjust a manual dial. The 4D armrests travel up, down, forward, backward, inward, and outward; they also coordinate with the chair's 130° recline so the arms stay supported through the full sweep of movement. The seat measures 51.6 cm across and height adjusts between 46.0 and 56.6 cm, making it compatible with standard desk heights throughout a home office. The waterfall-edge cushion, at 9.7 cm thick, eases pressure at the front of the seat. Seat depth is adjustable from 64.3 to 92.5 cm to suit different body sizes. The polished aluminium 5-star base with caster wheels glides across hard flooring without scraping. Overall width is 70.1 cm and total chair height spans 113.5-129.3 cm. Care is straightforward: wipe the mesh and frame with a dry or lightly damp cloth and avoid harsh chemical cleaners on the mesh surface. Assembly is required upon delivery. The chair is backed by a 5-year warranty.
