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

  • 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.
