1. Synchron 4000 Blue
The Synchron 4000 is the capacious version of the Stamina 3000.
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.
Ergonomic Adjustments: 
  • Back Height: easily adjusted by loosening the right hand knob, raising or lowering back, and re-tightening. Lumbar support is built in.
  • Seat Height: adjusted with the right front lever that controls the pneumatic lift
  • Seat Angle: adjusted independently of the back angle with the right rear lever. Can be locked in any position.
  • Back Angle: adjusted independently of the seat angle with the left rear lever. Can be locked in any position.
