Perfectly refined. Inside and out.

Siento is sleek. Sophisticated. And amazingly comfortable, thanks to LiveBack® technology embedded in the seatback. As you move, the back flexes, automatically changing its shape to support the entire length of your spine. So whether you’re leaning forward, reclining, or somewhere in-between, your chair conforms to your movement. All you feel is comfort.

  • LiveBack®

    The seatback flexes to match your movements, providing full support for your entire spine, including the lower back.
  • Back Tension

    Set the amount of resistance that you want as you recline.
