What makes Ergotron 33-349-200 the most popular sit-stand desk converter? Ergotron 33-349-200 workstation comes with dual benefits - it lets you alternate between sitting and standing at work, and even has the option for two displays. Both these benefits together can provide ergonomic relief as well as increase in productivity. This workstation is easy to install and attaches to the front of the desktop.

This workstation's height adjustment assembly can handle a maximum load of 25 lbs. That includes weight of 2 monitors, worksurface and keyboard tray.

Convert any surface into an adjustable-height standing desk with the attachment of the WorkFit-S. Make computing comfortable for prolonged periods - stand up whenever you want.

This sit-stand workstation is extraordinarily simple to use. With the push or pull of a hand, you can instantly raise or lower your keyboard and display in one easy motion, yet all the while the system will remain stable throughout your work routine.

Please note that depth adjustment for monitors is not possible in this WorkFit-S. Two monitors are fixed on a horizontal crossbow. However you can buy an adjustable tilter, which allows monitors to tilt up and down and side to side but there is no depth adjustment.

  • Studies show an average productivity increase of 20–30% when using two displays instead of one
  • 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

q I need this unit with the laptop mount on one side.

Please choose the LCD/Laptop conversion kit under “option 8” to be able to mount your laptop next to your monitor.

q Does the keyboard tray come with this model?

Yes, it does. The keyboard tray that comes with this WorkFit-S has the dimensions 0.25"H x 27" W x 9" D. However if you are looking for a keyboard tray with more depth, it is sold separately (0.25"H x 27" W x 11" D) as a part of Option 4.

q I want to order this workstation with worksurface. What are all the options?

The workstation comes with everything seen in the image: Height-adjustment column, Desk clamp, Crossbar, Two LCD pivots, Worksurface, Large keyboard tray. All the options (grommet mount, document/tablet holder, wrist rest, floor mat and so forth) are extra and sold separately

q I'm not sure I need the worksurface option. Can the worksurface be added later?

Yes, you can buy a workstation without worksurface. You have the option of adding worksurface at any time.

q I have been using this WorkFit-S for a couple of years now and so have my co-workers. I noticed that my monitors do not go as high as that of my co-workers despite being mounted on same height desks. Why? Is there some problem with my unit?

Over time some of the lifts lose their range of motion just out of usage and wear and tear and may need to be re-calibrated. On your unit, please put your hand on top of the front column (front column slides up and down on the bigger back column) and push down hard with your weight to force the unit to slide down all the way (past the initial stopping point). This realigns the sliders in the unit and frees up the range of motion on the top and bottom end. This is absolutely normal and nothing to be concerned about.

Great Product

by Anna S, Aliquippa, Pennsylvania, Dec 06, 2017

Having the option to sit or stand is great! Quality product.

great Product

by Erik E, Fairfax, Virginia, Oct 23, 2017

it does exactly what the employee was looking for, thanks for the streamlined installation program as well.


by Theresa S, Olathe, Kansas, Jan 24, 2017

I have ordered several of these products and will continue to buy more as needed. The WorkFit-S, Dual Monitor with Worksurface is a great piece of equipment,easy to assemble and use. To place an online order is simple, should you need assistance the "chat" is instant and efficient.
The orders are delivered within 2-3 business days. Also and most important the customer service is excellent.

Great Product

by Roxane P, Oregon, Jan 20, 2017

We ordered this for one of our staff. The product is heavy duty and functions very well. This product has allowed her to be able to raise her workstation enabling her to stand or lower it to sit while working. For staff with back issues, this is a wonderful product.

Dual Monitor Worksurface

by Judy C, New Mexico, Jul 07, 2016

All employees are very satisfied with the worksurface. Would recommend. Thank you for quick service.

Perfect solution

by Viola T, Oregon, Jul 05, 2016

This was the perfect solution for a client who had back surgery and needed to be able to alternate between sitting and standing to work.

Very Nice product

by Greg O, New York, Jun 28, 2016

Works smooth and quiet. Wish the monitors mounts had a ball and socket mounts to allow for left and right twist.

Relief from sitting for hours

by Linda G, Texas, May 18, 2016

This sit-stand desk is truly a miracle for me. I can now work for four hours at a time without sitting the whole time. It eases my muscles and allows me complete my work on time. I would definitely recommend this product to anyone with a need to sit and stand periodically (which is almost everyone).

Easy to use, nicely calibrated

by Bethany F, Michigan, Apr 27, 2016

Getting all the parts together took a little work, but I was impressed once it was assembled that it needed no adjustment. In operation, super easy to use and makes my work day much nicer. It does take up quite a bit of space on my desk, but was a much better fit than another model that just sat on top of the desk, so if your desk surface is shallow-ish, this might work for you. The keyboard sits pretty far out from the front of the desktop, so make sure you account for a reduction of 18-24" in floor/chair space. Standing up, your chair has to go somewhere: if you don't have enough room, you could trip over it!

Overall, I like this and think it has met my goals. I get to move around a little instead of staying seated all day!

Ergotron is a perfect solution

by Ann D, California, Sep 29, 2015

When an employee needs a sit/stand computer set up and their workstation or desk cannot accommodate a height adjustable table, the Ergotron is the perfect solution. It clamps on so removing it is really easy and no damage is done to the desk. In my many years as a facilities manager, I have purchased about five Ergotrons. In every case, the user was very, very satisfied

Best of Both Worlds

by Nancy O, Utah, Jul 06, 2015

I love my workstation. This product enables me to put healthy choices in my life by being able to stand for a good portion of the day. My back was bothering me from sitting all the time, so this has been a lifesaver.

Love this product

by Sandra B, Minnesota, Apr 16, 2015

Love the size of the writing surface but would like it if the monitors could go a little higher up. Also, we modified the keyboard tray so the keyboard could be at the right angle so the wrist does not bend up.

Love this!

by Lori O, New York, Feb 27, 2015

I purchased this for my office, I am a secretary, we also purchased two other units for our building principal and guidance counselor. We all love it! I feel way more productive (I stand 75 - 80% of the day). This unit is sturdy and easy to install, I would highly recommend it.

My WorkFit-S, Dual Monitor with Worksurface

by Robert T, California, Sep 15, 2014

This was my first time purchasing an ergonomic monitor, keyboard and work surface stand. I received the product last week and assembled it over the weekend. It is an investment. I like standing and the passive nature of this item ensuring that I think first before sitting. I had to modify how the unit attaches to my table which was easy to do. I removed the vice that attaches to the table which was easy to do. It was easy to assemble and works great. I would rate the quality of construction high too. The persons I spoke to before I purchased the item were helpful too.
