Detail Description 

Ergonomic essentials for anyone, anywhere. Serious support meets a lighter aesthetic. Steelcase Series 1 delivers performance, style and choice with the quality you’ve come to expect from a Steelcase chair, all packed into a small footprint and an even smaller price.


  • LiveBack™ flexor system in the backrest conforms to your body and moves with you to support the spine as you change postures
  • Adjustable lumbar support dials in comfort  
  • Weight-activated tilt mechanism responds automatically as you sit and move – with one additional tension setting to increase the resistance you feel as you recline and an upright backstop locking you in an upright position 


  • The weight-activated tilt mechanism is synchronised so the seat and back work in harmony with each other, keeping the body securely supported in the chair and feet firmly planted on the floor so you can recline without leaving your optimal zone for seeing and reaching your work


  • Strong yet pliable foam with adaptive bolstering (air pockets under the foam) in the seat conforms to the body and creates pressure-free comfort
  • Fully adjustable armrests raise up and down, pivot in and out, and shift forward and back and side to side, to provide steady support for your arms so your shoulders can remain in a relaxed position
