The question of stability of standing desks is actually a very important point, especially if you plan to use the desk for several monitors and generally for quite heavy work devices. I recently went through this process myself and can share some observations. When I chose the standing desk frame only from https://www.progressivedesk.com/collections/desk-frames, it was also important to me that the desk remained stably stable, especially at the maximum height. Indeed, there is a difference between frames with one and two motors, and this is not just marketing. Models with two motors provide smoother and more stable movement, especially when it comes to heavy devices. I chose a model with two motors and a reinforced structure, since I needed to place two large monitors, a system unit, a keyboard and other equipment. By the way, the table rises very quickly, and at all levels, including the highest, there are no vibrations or wobbles. This is probably the most important thing for me, because I often change the height of the table during work, and stability is really critical. If I had chosen a model with a single motor, I think the table might have wobbled or not moved as smoothly at higher levels.

Dual-motor frames are significantly more stable, but for most people who don't use the desk for super-heavy workloads, single-motor models are fine. I use one myself, from ProgressiveDesk, and I think it's a good option for casual work if you don't need to change the height too often.
