Finding a table for a corner shouldn't be hard. When it becomes a bit more challenging is when it needs to be different things at different times. A piece that works with everything else in the room, is the right height and depth, is light enough to be carried to different locations depending on how many people are using the space and for what purpose.
This pair of Brancusi style tables could be stunning stacked when not being used.
Cool Brancusi style side tables
Love this silhouette, but when I noticed the weight (55 lbs.) it just wouldn't be practical for shuffling around the room.
Also an interesting piece that reads like sculpture.
Found these on Houzz, lightweight and stackable, they also soften the right angles of a corner with the curves of its repeat pattern.
I like the delicate detail and the way these work, one slides out of the other, so no lifting.
This is steampunk beautiful.
Clean and neutral, the geometry of the design adds interest to an otherwise dull corner without overwhelming it
