Check all the feet and the movement path
A converter adds a moving assembly to a desk you already own. Start with the surface that supports its base. Measure the flat area between the wall, cable openings and any front bevel. The base feet need a level bearing surface. Confirm the desk can carry the converter plus everything you plan to put on it, including the effect of concentrated loads.
Compare the base, main platform and keyboard tray separately. Each answers a different question. The base determines where the unit can sit, the platform carries the screen and the tray affects typing reach and aisle space. Check the maker’s dimension drawing for any movement forwards as the unit rises. A platform size on its own leaves those other measurements open.
Tape out the base and mark the front of the tray where it will project. Sit down and pull the chair in. Check that the tray leaves you enough room to stand and that its underside clears the armrests. If the converter will sit against a wall, check the monitor and cable plug as well as the moving frame.
Measure key height before comparing lift ranges
Find the key height you need in both positions using the desk-height guide. Then measure the fixed top. If it is 73 cm and your standing key height is 103 cm, the keys need to reach 30 cm above the desktop. If the keyboard adds 2 cm, the tray surface needs to reach about 28 cm above the desktop. The main platform and tray can sit at different heights throughout the lift.
At the lowest position, try a mock-up of the extra height under your keyboard. A few centimetres of lift can make a previously comfortable desk feel high for seated typing. Check whether you can still sit back and work without lifting your shoulders. Take the seated measurement before relying on a generous standing range.
VIVO DESK-V000K for a shallower main platform
The black V000K has an approximately 80 × 40 cm main platform. Its published main platform range is about 11.4–50.8 cm above the existing desk. The separate tray has a 4 lb limit, around 1.8 kg.
The shallower main platform
VIVO DESK-V000K
The 80 × 40 cm main platform lifts vertically and has a separate keyboard tray. This is the black 31.5-inch DESK-V000K version.
Check the base and projecting tray with the dimension drawing, including the lowest position. VIVO rates the tray separately at 4 lb, about 1.8 kg.
- 80 × 40 cm platform
- 11.4–50.8 cm main platform height
- About 1.8 kg tray limit
The main platform is rated at 33 lb, about 15 kg. Check the weights on each level, including the mouse, keyboard and anything you rest on the tray. Use the diagram for the 31.5-inch V000K version rather than the measurements of the wider models in the same listing family.
Duronic DM05D1 BK for more screen surface
The black DM05D1 has a 92 × 56 cm main platform and published main surface height of 16.5–41.5 cm above the desk. It gives a larger screen or extra accessories more surface if the existing desk has room for the base.
A wider platform
Duronic DM05D1 BK
The 92 × 56 cm main platform gives a larger screen and peripherals more surface. A separate keyboard tray rises with it.
Measure the 94 × 62 cm footprint and allow room for the tray to travel forwards as it rises. Include the converter and its equipment in the load on your existing desk.
- 92 × 56 cm platform
- 16.5–41.5 cm main platform height
- 2 kg tray limit
The main platform is rated at 15 kg and the keyboard tray at 2 kg. Weigh each item where it will sit. Measure the tray width and the space needed for mouse movement, even if the keyboard already fits. Check the monitor stand’s feet and position against the main surface.
Duronic gives a 94 × 62 cm base footprint and a 91 × 29 cm keyboard shelf. The assembly travels forwards as it rises. Mark the farthest tray position before choosing it for a desk beside a walkway.
Choose between a converter and a moving desk
A converter suits a desk you can already use at the low setting with the tray in place. When you need the whole working surface to move, compare compact standing desks. Check the seated minimum and foot position before spending money on either setup.
After assembly, follow the maker’s instructions for loading and moving the unit. Keep hands clear of the mechanism and run cables clear of the frame. Test the full intended travel with the screen visible and the lead ends accessible. At the highest position the plugs should stay seated and the lead should still bend gently. At the lowest setting check where the extra cable rests.
Common questions
How deep does my existing desk need to be?
Measure the converter’s actual base and use the maker’s placement instructions. Allow for its projecting tray, plugs and full travel as well as the main platform.
Does the listed lift range apply to the keyboard tray?
The quoted ranges here describe the main platform. Check the tray’s own height at the low and high settings, including your keyboard thickness.
Can a converter hold a monitor and a laptop?
Check the weight, contact points and footprints of both on the main platform. Apply the keyboard tray’s separate load limit to the items you use there.
Will a converter make my desk too high when I sit?
Try the lowest keyboard tray height with the chair and feet set for work. If the keys sit too high in that trial, compare a different converter or a lower worktop.
Can I clamp a monitor arm to a converter?
Check that both makers approve the attachment for that exact converter, arm and load. Confirm the required bearing area and how the assembly moves at each height.
