YORSERNY Mesh Office Chair, Ergonomic Office Chair, Home Office Desk Chairs with Headrest, 90-135° Tilt Lock and Breathable Backrest & Lumbar Support, 5D Armrest, Computer Chairs — Open-Box, 27% Off

Our office chair truly meets your needs: it keeps your lower back in its natural curve while you're seated, locks a 135° recline that stays put so you can lean back with confidence during breaks, and uses mesh that pulls heat away before you start sweating. We skipped the gimmicks and put the budget into five things: lumbar support, a Class 4 gas lift, premium stretch‑resistant mesh for the seat and back, a recline lock, armrests and headrest. 30‑day free returns and refunds.

Mesh office chair — why choose mesh? Because foam seats fail in three ways: the longer you sit, the hotter they get, the more they sag, and the more they numb your legs. Our curved mesh seat and back — with active airflow to keep you dry, stretch‑resistant material that won’t sag, and a contoured design that distributes your weight evenly without cutting off circulation in your thighs.

arm chairs: Thick PU-padded armrests with metal-reinforced joints that lock securely for height adjustment — no slipping. When you recline deeply, the armrests follow your movement smoothly. They aren't locked in place — this is intentional. If they locked, you'd have to bend over every time you adjusted them. So we chose a smooth, effortless follow-along design instead. Just lean back slightly, and the armrests move with you.

90° for focus, 110° for relaxation, 135° for a quick nap — a three‑position mechanical click‑stop lock that won’t slip or wobble. It comes with a 3D adjustable headrest, featuring high‑elasticity mesh that keeps air flowing so you stay cool and sweat‑free. The mesh conforms naturally to your head’s contour, providing gentle support without pressure points or sagging. When reclining between 110° and 135°, it precisely cradles your neck to relieve stiffness.

2‑inch adjustable lumbar support precisely aligns with your L1–L5 vertebrae, evenly distributing your weight to reduce lower back pressure by 50% and effectively relieve fatigue.

Suitable for users from 4′9″ to 6′3″ in height. office chair, desk chair, gaming chair, computer chair.
