Atlas probably has the most handsome, most modern furniture like shelving system of all the shelf systems we've looked at to date. And its probably also the most expensive. But there is no denying that it is very beautiful. And most important it works very well as a vertical desk shelving element.
Atlas shelves have several things going for them beyond their good looks. First they have shelf depths in 6" increments, so you can get the 24" desktop you need for a vertical desk, and the 18" deep shelf you want if you are going to make an equipment shelf, and there are of course book depth shelves as well.
Another important feature of the Atlas shelves is their extremely low profile shelf supports. In most cases the shelf support is no thicker than the shelf itself which means that rolling your mobile desk under the desktop shelf will be unhindered, and you can adjust the height very close to your desktop.
The verticals are also available with feet, not that they would be freestanding - I think they look like they need to be fastened to the wall, but if you were not on your studs, and you could not rely on the wall to support the verticals, then the feet would bring the weight safely to the floor.
