Synchron 4000-Standard/Fabric Task Chair by GK.


Synchron Series C4 (Standard/Fabric) By GK Chairs

**Disclaimer This Product Does Not Apply To Flat Rate Shipping**

(Spacious version of the Stamina 3000/Also available in Cleanroom and ESD versions)

To make the chair comfortable for a larger user, we changed the seat to a wider waterfall-style seat pan and a larger back.  Both add comfort and support where you need it most.
The ergonomic features are controlled by a heavy-duty Independent Tilt control.  This gives you independent control of your seat height, back height, seat angle, and back angle.  Additional options like upholstered trigger arms, adjustable footrings, and optimization for varying bench heights will make this the only task chair needed for a more capacious user.
The Synchron 4000 Series production chair gives sturdiness of a task chair and the comfort of an office chair. (**Shown with optional Adjustable Trigger Arms) This is the non-ESD, non-Cleanroom, Standard version of this chair in Fabric.
