Frequently Asked Questions

q My desk work station is 22" deep. Here it states the Ergotron WorkFit-T needs 24" deep. Will this still work with my desk?

If your desk is only 22" deep than 2" of the platform will hang over your desk, note that this can also affect the sturdiness. Are you using single monitor or dual? WorkFit-S could work for you as well and you only need 17" deep desk:

Very Happy

by Tesaro G, Waltham, Massachusetts, Jan 12, 2018

For the money, the best you can buy. Fits two monitors. Easy to install - lighter than Varidesk and sturdier than other models.

Wife loves it

by Charles M, Houston, Texas, Oct 19, 2017

One of the best things my wife says I have ever gotten for her. She started working from home about a year ago and has been complaining about sitting so much and wanted a stand up desk. These are the types we use at work and after shopping around I decided to get her the ergo model. More expensive than others but the quality and ease of use is phenomenal. I'm sure she will be using this for many years.

Excellent Purchase

by Melissa, Columbus, Ohio, Jul 13, 2017

This is a great product with a good price. We bought one for the majority of our IT department and HR folks. Everyone has loved it and actually uses it for its intended purpose (frequently sit and stand throughout the work day). The zip ties and mesh tube really help to make the wires look clean and organized. It is heavy, but makes for a sturdy space and glides easily with different secured locking positions. We really love this product!

it's ok

by Yamira M, Garden Grove, California, Apr 25, 2017

I does lift my work station however if the keyboard tray was made for the ergo keyboard which is bigger it would be great. Also it would be even better if it were made for an L desk where the computer is in the coroner.

Excellent product.

by Robert M, North Dakota, Feb 24, 2017

Love it! Easy to use, smooth transition and not too heavy. Having the flexibility to stand up anytime and continue to use my computer or view documents on my screens. It has helped with back/hip tightness being able to stand up whenever and continue working at my desk. Feel more alert at the end of the afternoon from not sitting as much during the day.

Super sturdy and functional

by Gretchen R, Texas, Oct 20, 2016

We have a couple of these in our office and everyone loves them. The construction is very good. Work surface with drop for keyboard is perfect.

This Desktop is Super!

by Lisa C, Colorado, Sep 26, 2016

Very easy to set up and use. I was having trouble with my shoulders while sitting and needed to stand for my job. We already had the dual monitor set up and this desk top is perfect for adjusting. It is super smooth during the transition from sitting to standing and very stable. Really thankful I decided to go with it!

This product is Awesome

by Barry R, Florida, May 20, 2016

Easy to use. Incrementally adjusts to the perfect height. Posture perfect when standing. The Ergotron Desk is has been a life changer.

Very Satisfied

by Kim W, California, Mar 30, 2016

The employee that the adjustable desk was order for, loves it.

Enjoying desk

by Mark, Illinois, Mar 22, 2016

I have greatly enjoyed the Ergotron desk. It is easy to raise and lower. There is ample space for the monitor, phone and papers or books to refer to when working on projects where I need to see them and type simultaneously. There is some vibration of the monitor while I type and the desk is raised. There is not vibration when it is lowered. Monitor-vibration during typing was reported in the reviews of a competitors product, but not for reviews I read on the Ergotron prior to purchasing it. However, the positives of being able to stand outweigh this minor concern.

Great Product

by Brian L, Massachusetts, Mar 17, 2016

I purchase these for the employees of the company I work for and they all love them!

Met all my needs and expectations

by Bret, Hawaii, Mar 14, 2016

I would recommend the Ergotron to anyone looking for an adjustable desk option. It is very stable and easy to raise and lower. No assembly required. It's ready to use right out of the box. After trying co-worker's Varidesk, the Ergotron is far superior in design and function.


by rich v, New Jersey, Mar 14, 2016

Sturdy and well built. Highly recommend.

It's great!

by Barb S, Michigan, Mar 04, 2016

The desk works well and set-up was fairly easy. It's nice to be able to lower it every so often if I'm sitting down doing a combo or paperwork and computer work. The keyboard section fits my Apple keyboard (w. 9 key) plus my mouse pad with about 2" to spare. It's nice to be able to adjust the height of the monitor to fine tune it but once done I haven't had to change it. The only suggestion I have would be to be able to swivel the monitor so when I'm typing it faces me at a slight angle being fixed straight. Perhaps if I didn't have my mouse on the keyboard section I wouldn't be off to the left of the monitor but I do. I feel that it was worth the investment.

Review on WorkFit-T

by DLD, Colorado, Feb 05, 2016

I really enjoy the WorkFit-T Sit-Stand Desktop Workstation, I would have given it five stars if the keyboard tray was adjustable. Something to think about for the future workstation :)

Ergotron 33-397-085 WorkFit-T Sit-Stand Desktop Workstation

by Doug B, Minnesota, Jan 06, 2016

I have a large apple monitor and this workstation moves easily up and down without any fear of this monitor falling off. There is plenty of space for the MacBook Pro laptop to sit adjacent to the monitor. The Workstation is very sturdy and well-built. The lower shelf is large and my secondary keyboard fits on it with room for my mouse to move. The Workstation sits on top of my desk squarely with no wiggling of it or the monitor. I find that I am now sitting about 60 % and standing about 40% throughout my work day. I am very pleased with this Workstation.

I feel so much better during the work day!

by Lisa O, Minnesota, Nov 19, 2015

I truly appreciate the stand up work station. I no longer have the feeling that I am part of the chair at the end of a work day. I feel so much better standing and rarely set it down to the seated position, which really proves it's better to stand and be mobile.

Love my Ergotron!

by Kathryn D, Kansas, Oct 27, 2015

First I ordered the Ergotron that clamps to my desk. It did not work at all for me. My workspace was too small. So I ordered the 33-397-085 and it works great. I tend to lean in my chair while seated, so now I can stand when working on the computer for a long period of time. It's much better for my posture. But I also leave it up and use it in the standing position for short computer jobs. It's healthier to alternate sitting and standing often. Toward the end of the day if I'm tired, I lower my station and sit at the computer, and its very comfortable that way also. I had to choose a smaller mouse pad, but that's the only adjustment I have made. Also, it's so easy to raise and lower. Again, I love it.

Love it

by Sara Z, Minnesota, Oct 09, 2015

This has been a great add-on to my existing large, L-shaped desk. I enjoy starting the day zapping through emails standing and then being able to sit when I need to do more focused work. Will be ordering the dual monitor arms as well now that I know I like this product.

This desk has a smaller footprint than other desks of this type. They also tend to fit better under existing cabinetry

by Jay M, Washington, Sep 28, 2015

See headline above. Only drawback is that they are more expensive.

Perfect for my office

by Clell i C, Oklahoma, Sep 04, 2015

It is solid, functional and easy to operate. Leaves lots of workspace on the raised platform.


by Eva M., California, Aug 28, 2015

I am loving my new desktop. Very easy to use and works flawlessly. I have two monitors and use this with no problems. Highly recommend.

I Love It!

by Dustin W, Arizona, Jul 07, 2015

Just finished setting up my new Ergotron WorkFit-T Sit-Stand Desktop Worktop and I love it. It has totally improved my posture and ergonomics while sitting, but I don't really want to sit anymore now that it's so easy to work standing up. I bought the dual monitor stand for my two 24" flatscreens and it works nicely, reduces clutter and provides me more usable desk space. Also bought the floor mat and Steppie and love them both. Thanks for a great product!

Smooth operation

by Sue D, Colorado, Jun 23, 2015

I love this workstation. It is built with high quality materials, it is sturdy and stable. It's super smooth operation transitioning from sitting to standing and back to sitting positions is impressive. The desk top provides me with ample work surface.


by Cyndie R, Colorado, Jun 22, 2015

I love my new Ergotron desk. No more back pain from either sitting all day or standing all day. A combination of both working styles is awesome. Thanks

The product is fantastic

by Kim C, Texas, Jun 22, 2015

So far it has been fantastic! I stand all the time and love how easy it is to adjust. I did not appreciate the extremely long wait time to get it after my order.

This is a great solution!

by Steve H, California, Apr 25, 2015

This workstation is affordable and allowed me to keep my existing furniture. It is solidly built, has a low, unobtrusive profile in the down position, and stays nicely within the footprint of my desk when raised. It's easy to raise and lower, locks nicely into place at any level and is stable enough to lean on when raised. I put my two existing monitors on the surface and there's plenty of room left for notepads, my coffee cup, cell phone, files, etc. It was easy to install and comes with an attractive conduit for monitor cables that keeps them neat and out of sight. I took a little chance and ordered it before any had been shipped. After two weeks with it, I'm very happy with my choice, and find I'd rather stand at my desk because it's so easy to work with this product.
