Improve Posture: Unlike traditional chairs, this ergonomic kneeling chair uses a kneeling design to help align your back, shoulders, and neck, ease sciatic and lower back pain, and reduce slouching for better focus and efficiency Rocking Base: Our kneeling desk chair's curved base supports natural forward and back rocking to help avoid a fixed, stiff sitting position and support more ease while reading, thinking, or working Thick Cushions: Seat and kneeling pads of the kneeling office chair use foam to support hips and knees for lasting comfort, help hold their shape over time, and the linen fabric provides airflow and heat release for a cooler, drier sitting feel Stable Frame: Solid wood frame with 265 lbs/120 kg load capacity, bottom strips add grip to help limit sliding or tipping and help avoid floor scratches
