Monhey Ergonomic Office Chair, High Back Desk Chair with Lumbar Support

2.2" Height-Adjustable Lumbar Support – The lumbar pad slides through a 2.16" range so it lands exactly on your lower back curve, offloading pressure instead of leaving your waist floating. Built for 8-hour work-from-home days when a fixed lumbar leaves you sore by afternoon. 90° Flip-Up Armrests & 90°–125° Recline – Armrests flip up 90° (vertical only, not 3D/4D) so the chair sits flush under your desk and frees up floor space. Recline 90°–125°, raise the seat 3.2", and swivel 360° to shift posture through the day. Breathable Mesh Back for Long Sitting – Nylon mesh backrest keeps air moving across your shoulders and spine, so you stay cool through back-to-back meetings. A good fit for home offices, study rooms, and reading corners where you sit for hours. U-Shaped Cushion & Sturdy Base – High-density foam in a U-shaped seat contours to your thighs and hips to ease pressure points. A sturdy metal base and five-point star base keep the chair stable as you shift weight. Fits 5'3"–6'3"users. Easy to Assemble in About 15 Minutes – All screws and tools ship in the box, and the illustrated manual walks you through assembly in about 15 minutes with no extra tools needed. Confirm before ordering: this chair fits 5'3"–6' users and the armrests flip up 90° only.
