  • Easily and simultaneously lift keyboard and monitor to your height for unsurpassed comfort

  • Counterbalanced adjustment points using patented Constant Force technology allow instantaneous, tool-free re-positioning while you work

  • Improve your energy and productivity by standing or sitting as you work, and then switch positions whenever you choose. This work style encourages healthy movement throughout the day

  • Promote fitness and comfort as you compute, reducing potential back and neck pain by adding movement into your work routine in a truly ergonomic workstation

  • Double your view - and move it too! With two monitors you can save time by using multiple applications at once - eliminate toggling back and forth between documents and programs

  • Burn more calories by choosing to stand for periods of your work-day; periodic standing also promotes greater bone density and better sleep at night. WorkFit-S counteracts an increasingly sedentary workstyle

  • Studies in office ergonomics show productivity increases 12%–18% following an ergonomic intervention where employees are provided with well-designed ergonomic furniture



Frequently Asked Questions

Question: I have a Dell S2340L monitor and a laptop. I want to know if I can fit them on this WorkFit-S without buying any additional accessories. Answer: The WorkFit-S 33-349-211 is not compatible with your Dell Monitor as your monitor is not VESA compliant, that is, your monitor does not have holes (VESA pattern) on the back of the monitor. In situation like yours, we recommend the WorkFit-TL. There is no installation, compatibility restrictions involved in WorkFit-TL. Just place your monitors on top of the WorkFit-TL's worksurface, connect your computer and start working.
