Easy controls, a comfortably large work surface, and attached keyboard tray make this desk riser a perfect choice for your existing setup.

Frequently Asked Questions

  1. Is the clamp mount more stable than the freestanding mount?

    Both mounts are very stable and whichever one you choose to use depends on the parameters of your current desktop setup. We recommend using the clamp mount because it does allow you to bring the keyboard tray below the level of your desktop. So in that sense, the clamp mount is more stable. But if you go with the freestanding mount, your Standing Desk Converter will be very stable as long as you keep your keyboard tray above the horizontal plane of the desktop.

  2. Does this product ship fully assembled?

    Almost! Just attach the keyboard tray to your Standing Desk Converter and you will be standing in no time!

  3. Can I put monitor arms on this?

    No, the Standing Desk Converter does not support monitor arms. If you would like a desktop converter that will allow a monitor arm to be attached check out the Standing Desk Converter.

  4. Does the "freestanding" version of the Standing Desk Converter connect to the desk at all?

    No, the Standing Desk Converter Riser just sits on top of your desktop. This makes setup a breeze and also allows you to easily move the Standing Desk Converter Clamp.

  5. Where does the keyboard tray rest when the unit is lowered?

    When the Standing Desk Converter Riser is lowered the keyboard tray will sit at desktop level. When the Standing Desk Converter Clamp is lowered the keyboard tray will hang 3.2" below the horizontal plane of the desk.

  6. Is the keyboard tray palm rest removable?

    Yes, the keyboard tray palm rest can be removed using an Allen wrench.

  7. How does the UDA100 Riser or Clamp Standing Desk Converter compare to the others?

    The Standing Desk Converter comes with two mounting options, a Freestanding Riser or Clamp. Both mounting options can hold up to 28.6 lb. When the Standing Desk Converter Riser is lowered the keyboard tray will sit at the desktop level. When the Standing Desk Converter Clamp is lowered the keyboard tray will hang 3.2" below the horizontal plane of the desk.

    The E7 Electric Standing Desk Converter has the greatest weight capacity of 110 lb. The freestanding mount makes this model ideal for desks that don't have the option for drilling and clamping mounts. Unlike the pneumatic Riser or Clamp, the E7 Model is electric and has an add-on accessory arm. The E7 adjusts entire workspace electronically with the push of a button and contains memory presents and is the best alternative to a full standing desk.

    Like the Rise or Clamp model, the Adapt Mobile Laptop Standing Desk Converter is also pneumatic and compatible with any size laptop. Various installation methods are possible with both bolt-in and clamp mounting options. This sleek model can also hold up to 15.4 lb and offers a 360-degree display rotation.

    The E3 Standing Desk Converter offers an ultra-portable sit-stand solution for kitchen islands, tables, craft corners, and more. This grab and go design can safely hold up to 11 lb, ideal for smaller laptops.

    If you're in need of multiple screens you might try the Lift Standing Desk Converter. This option adjusts in seconds via easy-to-use handles and can hold up to 33 lb.

    The Front Clamp Standing Converter features a tiered keyboard tray and mousing platform. The sturdy clamp mount attaches to most desktops and can hold up to 33 lb.

  8. Is it possible to have my keyboard tray go lower than the surface of my desk?

    If you want your keyboard tray to go lower than the level of your desk, then you must order the clamp mount.

  9. I have a shallow desk, will the Standing Desk Converter still work?

    If your desktop is shallower than 23.5" then you must use the Standing Desk Converter Clamp. Otherwise you will not have room on your desktop to support the freestanding base.

  10. Is the keyboard tray adjustable on the UPLIFT Standing Desk Converter?

    The keyboard tray will not adjust separately from the Standing Desk Converter. It will only move up and down at a fixed position in combination with your desktop converter. We recommend going with the Clamp because it will allow your keyboard tray to rest lower than the surface of your desktop when the converter is at its lowest position. This will offer you a better ergonomic setup while you are seated at your desk.

  11. How does the Standing Desk Converter lock in place?

    Once you move your Standing Desk Converter to the desired height, just release the paddle and your desktop converter will lock in place.

  12. Will the weight of the items I place on top of the Standing Desk Converter affect how quickly it moves?

    There is a tension control adjustment on the back of the Standing Desk Converter. To adjust the tension to the weight of your desktop items, turn the large Allen wrench clockwise or counterclockwise.

  13. My monitor is pretty heavy, will the Standing Desk Converter support it?

    As long as your monitor and everything else you place on your desktop weighs no more than 28.6 lb, the Standing Desk Converter will be able to safely do its job.

  14. What is the ANSI/BIFMA X5.5-2014 standard?

    ANSI/BIFMA X5.5-2014 (section 5.3, 5.5, and 16) tests to ensure our converters meet or exceed strict requirements for work surface and keyboard tray loading and converter cycle testing.

Riser Mount


Choose either a freestanding or clamp mount. The freestanding mount lets you place the system anywhere on your desktop, but the keyboard tray will sit on top of the desk and will not go lower than the desktop. The freestanding mount requires 23.5" minimum depth for installation.

Clamp Mount


The clamp mount requires that you clamp the system to the back edge of your desktop. This allows the attached keyboard tray to adjust lower below your desk surface for a more ergonomically correct typing position for sitting and standing. We highly recommend the clamp mount option unless your desk setup requires the freestanding mount. The clamp mount requires 19" minimum depth for installation.
