SIS Xtreme Height Adjustable Workstation Description:

Xtreme collection of crank and electric tables is available in all sizes including cornerflex configurations.

The crank version permits a 5th percentile female worker to adjust the tables from a seated position with a minimum sustained force. Sit to stand collection of crank and electric tables available in all sizes.

Generation IV xtreme workstations are available with single or dual surface tops when fitted with spring adjustable keyboard units. Workstation designs include rectilinear models from 30” to 72”, 42” and 48” corners, 72” corner combi’s and full oversized cornerflex units.


Generation IV computer support furniture adjusts to serve everyone. They meet or exceed all existing domestic and international standards for safety, durability and ergonomics.


Generation IV xtreme is distinctive in its exceptional range of motion. Adjusting quickly and easily from a sitting to standing position, it is the ideal computer solution for all office applications and especially those demanding advanced ergonomics and extensive flexibility.


  • Available as full tables or frames that can be integrated with new or existing work surfaces.

  • High durability and vertical horizontal integrity are assured through the use of steel constructed frames.

  • Easy-glide casters are available for quick table re-arrangement or casual task groupings.

  • Perforated privacy and modesty panels can be added for open space office concepts.


Spring adjustable keyboard mechanisms convert single surfaces to a duplex, dual surface workstation. The keyboard platform adjusts ± 6” with a simple squeeze on the paddle and tilts ± 15˚.


Unique support “beam” and leg design can be easily reconfigured to promote extreme flexibility. For example, a 72” workstation can be easily converted to a 42” corner table simply by changing the beam and tabletop. Add an additional leg to the extra beam to create another workstation.
