My little world of breakfast nook furniture
There are actually quite a few differences between a conventional dining arrangement and this. A kitchen corner nook is specifically designed to be the most ergonometrically efficient arrangement while minimizing utilization of space. The arrangement is intended to fit into corners, and thus takes up very little space for itself. Their natural space management benefits aside, they also have the advantage of being visually appealing. A kitchen corner nook might be small and spartan, but that doesn't stop them from being tasteful and elegant.
