Kneeling chairs were designed upon the ergonomic concept “A strong back is a healthy back”. By promoting good posture, the chairs strengthen the lower back muscles helping spinal alignment and support. Designed in the 1970’s, kneeling chairs are recommended by medical professionals around the world. This chair has a five year warranty and a maximum weight limit of 280 lbs. The 1450 Classic Kneeling Chair by Jobri has a classic wood frame and a thick pad on the seat and knee support. Also features height adjustment and wheels for easy movement of the chair.
