Ergonomic Home Office Desk Chair With Massage Lumbar Support, 4D Headrest, 5D Armrests, Adjustable Back Height And Seat Depth.

Features

• The adjustable back height and seat depth allow precise customization: lift the backrest up to 2 inches to match lumbar curvature and slide the seat forward or backward by 2 inches to optimize thigh support and circulation, ensuring proper posture and reducing pressure on the lower back and knees during prolonged sitting.
• The full-body breathable mesh construction wraps both the seat pan and backrest in high-elasticity, tightly woven mesh that promotes constant 360-degree airflow—keeping the body cool and dry, minimizing sweat accumulation, and maintaining consistent comfort even during extended use in warm environments or high-focus tasks.
• The 5D armrests enable independent adjustment in five directions: vertical height, front-to-back sliding, side-to-side width expansion or contraction, 360-degree rotation, and horizontal lateral shift—ensuring elbows rest at perfect 90-degree angles and shoulders remain relaxed throughout the day.
• The 4D headrest provides vertical height adjustment, horizontal sliding, forward/backward tilt, and angle locking to fully accommodate varying neck lengths and preferred viewing angles—supporting healthy cervical alignment whether you're typing, reading, or taking short breaks.
• The integrated 3D massage lumbar support delivers rhythmic, targeted vibration therapy directly to the lower back region without requiring batteries or external power—offering immediate tension relief, improved blood flow, and reduced muscle stiffness during work, study, or relaxation sessions.
