Steel kneeling Posture Chair - Our Newest Ergonomic Knee Chair. By easing your hips into a forward tilt position, the kneeling chair encourages an upright posture that correctly aligns your back, shoulders and neck. Kneeling chairs are a super sitting alternative for people with lower lumbar, sciatic and hip problems. A manual height adjustment feature makes it easy to find the right configuration to match your table, while the dual-wheel carpet casters let you wheel this chair from your desk to the conference room.  Multiple color choices bring a sophisticated and unique look to your work space. The chair frame is made of high quality wood and steel but adjustable, so it will suit most people in different age. The pads on the chair are ultra-comfortable with our unique high quality material so it will not be a pain if you need to be seating for hours long. There are  wheels at the front and back  so the chair is easy to more around. If you are not using it, the chair can be folded and storage space can be saved.
