Introducing Sigma.  A new mesh office chair whose cool looks make it the perfect choice for contemporary workspaces.   The breathable mesh backrest helps keep you cool and its simple adjustments will keep you sitting comfortably as you work. The headrest, backrest recline and lumbar support can all be fine tuned so you can find your special place.  The all black neutral finish will work well in any space.

  • This reliable office chair is great for workplace or home office environment.
  • Essential neck and head support is delivered by a height and tilt adjustable headrest.
  • Tensioned mesh backrest is breathable to help you keep your cool on warmer days.
  • The backrest is contoured for comfort and incorporates an adjustable lumbar support pad.
  • Simply slide the lumbar pad up or down to find the best position to support your lower back.
  • Padded seat with sloping waterfall front removes pressure on the back of the legs and encourages good posture.
