A standing desk won’t magically fix poor posture or help you lose weight, but it can offer health benefits.
“The primary ergonomic benefit of a standing desk (also called a sit-stand desk) is the ability to move throughout the day,” says Dana Keester, an ergonomics expert in CR’s Consumer Experience & Usability Research group, who led our evaluation. “Incorporating regular movement and postural changes throughout the day increases blood circulation and allows you to activate different muscle groups.”
You can even use a standing desk with some treadmills and exercise bikes.
While you’re sitting, a height-adjustable standing desk can also provide a more ergonomic and comfortable work surface than many fixed-height desks, which are too high for shorter users. Just like with a great office chair, adjustability is critical.
Other than the Ikea Bekant, all the desks we evaluated included a collision-avoidance feature, which is supposed to make the desktop retract if it collides with something. Our interest in this feature was sparked when a desk with collision avoidance pressed down on one participant’s lap hard enough to be painful and make the desk tilt back on its rear legs. He had to scramble to find the right button to raise the desk back up and relieve the pressure.
We didn’t score the desks on this feature, but we did spend time in the lab investigating how it works. The desks exerted anywhere from about 40 pounds to 80 pounds of force before retracting, depending on the model and the procedure we used in each of the trials we ran. Several desks have controls that are supposed to let you adjust the sensitivity. We tested the desks using the maximum sensitivity available.
One other note on safety: We declined to evaluate certain models we bought because they used an exposed driveshaft to raise and lower the desktop. If you’re shopping online, desks that use a driveshaft will usually say they have a single motor. But it’s often not clear whether the driveshaft is covered to prevent shoelaces, a child’s fingers, fabric from a skirt, or anything else from getting caught as it rotates. Desks with two motors, one on each side of the desk, don’t need a driveshaft.
Ashita Kapoor, CR’s associate director for product safety says: “After installation and assembly of your standing desk, if you notice any exposed components, make sure no obstacles are in the desk’s path.” As with all electric height-adjustable desks, you want to make sure children and pets are away from it during operation.
