Designed to resemble the human body’s spinal column, Teknion’s new RBT (responsive back technology) chair supports good posture through an ergonomically designed seat back that moves with the user. The seat back’s aluminum structure, which is covered in cushioned leather, maintains contact with the sitter, supporting the spine no matter which direction he moves and rotates. The highly responsive system—the first of its kind, says the company, to move automatically with the user to promote changes in posture—allows for various adjustments that increase the support for the lower, middle, and upper back. Available in a black or white, the chair can also bolster a stylish home office environment. Prices start at $1,400.
