ELJGET High Back Desk Chair with Adjustable Lumbar Support & Headrest, Mesh Computer Chair with Flip-Up Arms, Height Adjustable, 120° Tilt, Gray

"This ergonomic high-back office chair is designed to deliver all-day comfort and proper support for your work routine. Featuring an adjustable headrest, lumbar support, and armrests, it helps maintain healthy posture by supporting your neck, back, and arms. The 120° rocking function allows you to lean back and relax, making it ideal for short breaks and stress relief during busy workdays. The headrest adjusts in both height and angle to suit working or resting positions, while the flexible mesh lumbar support moves up and down as well as forward and backward to closely fit your lower back. A breathable mesh back combined with a high-density sponge seat promotes airflow and lasting comfort, keeping you cool even during extended sitting sessions. Flip-up armrests offer added versatility, allowing you to slide the chair neatly under your desk when not in use to save space. Smooth-rolling casters ensure easy movement across a variety of floor surfaces, while the sturdy base provides stable support for everyday use at home or in the office."
