Kneeling Posture Office Chair

The Kneeling Posture Office Chair is designed to promote an open hip angle (approximately 110°), which naturally aligns your spine into a neutral, S-shaped curve. This reduces the load on your lower back by up to 35% compared to conventional office chairs, according to independent biomechanical studies. The frame is built from solid European birch (Betula pendula) with a clear natural finish. What makes this chair unique is its base: instead of fixed legs, the birch wood rocker base is curved (a 30 cm radius of curvature) and sits on four rubberized anti-slip pads. This allows the chair to rock gently back and forth while you sit, engaging your core muscles and promoting micro-movements that prevent stiffness. The thigh cushions (angled downward, 35°) and knee cushions are both heavily padded with 10 cm of high-density foam (40 kg/m³) and covered in a breathable, moisture-wicking mesh fabric (100% polyester, black). The mesh has a 3D spacer construction that allows air to circulate, keeping your legs cool. Both the thigh pad and knee pad are height-adjustable in three positions (2 cm increments) via a simple pin system, allowing you to find the perfect knee-to-thigh ratio. The chair has no backrest; your upper body weight is supported by the angle of your shins against the knee pad. Maximum user weight: 100 kg (due to the rocking base’s stability limit). Dimensions overall: 62 cm width x 66 cm depth x 76 cm height. The thigh pad (seat) height from floor ranges from 48 cm to 52 cm. Assembly required: the rocker base attaches to the central column with four bolts, and the knee pad bracket attaches with two bolts. Estimated assembly time 15 minutes, all tools included. The chair is not meant for all-day sitting (more than 4 hours), but is excellent for active sitting tasks like drawing, writing, or short computer sessions. Warranty: 2 years on foam, 3 years on wood frame.
