A crooked couch is not what we need right now
One of the most satisfying things ever is to see straight lines or edges. It can be even relaxing to find everything nice and even. Symmetric things also give us a pleasant sense of balance, since everything is where it belongs. But it seems that other people have more chaotic preferences.
Something is unsettling about this couch, but we cannot put our finger on it. While this piece of furniture looks crooked and uneven, its seats are placed perfectly straight. It works like an off-putting optical illusion. It is a cool effect, but that is why we probably do not like it.
