Improve your posture and comfort with this ergonomic kneeling chair. This chair is designed to help you avoid slouching and hunching, which can cause back pain and poor body shape. By sitting on the padded knee cushion and tilting your pelvis forward, you can align your spine, shoulders, and neck in a natural way. This reduces the pressure and discomfort on your lower back and legs, especially after long hours of sitting or working. The chair can hold up to 220lbs and has a wide knee cushion to accommodate larger users. The foam padding is 5cm thick and provides a cozy seating experience. The chair also has a rocking function and three cross bars to ensure balance and durability. You can also attach two strips to the bottom of the chair to prevent sliding on smooth surfaces. The chair is easy and quick to install, and can be used at home or in the office.
