Frequently Asked Questions

  1. Why do I need the 4-Leg Conversion Kit?

    If you desire the lifting capacity of a 4-leg desk, this can help! Each leg is freestanding, allowing for custom configurations of your desk setup.

  2. How is this different from the 2-Leg to 3-Leg conversion kit?

    Our UPLIFT 2-Leg to 3-Leg Conversion Kit allows you to convert your current rectangular desk into a corner workstation with just a few under-desk additions! If you have questions about what style of desk is right for you, give our Sales Pros a call and we'd be glad to help!

  3. Why do I need a 4-Leg desk over a 3-Leg or a 2-Leg desk?

    We recommend purchasing a 4-Leg desk when you require a workstation with heavy duty lifting capabilities. Our 4-Leg desks lifts over 700 pounds of desktop and computer gear, so if your workstation setup is larger than average, this might be a more suitable desk for your than our 2-Leg or 3-Leg desks.

  4. Is this BIFMA Certified?

    Yes, the 4-Leg Conversion Kit completely meets all requirements of BIFMA/ANSI X5.5-2008 Test Sections 4.3, 4.5, 5.2-5.5, 6.0, 7.0, 8.0 & 15.0. If you have any questions about whether this complies with your office's standards, give us a call and we can point you in the right direction.
