Round beds
Like some sort of leftover scenery from an Austin Powers film, round beds were all the rage a few years ago. Seemingly cool and a bit different, it was considered the height of sophistication to have a round bed in your bedroom. These were often seen in the houses of basketball players, and so copied all around the world.
In reality, having a bed this shape made it more difficult to decide on room layout, harder to work out who sleeps on which side, and almost impossible to find the bedding that would fit. All in all, it really wasn’t worth it to copy the latest baller. Rectangular bed, normal bedding: a much easier life.
