Considering it's not a real office, yes, it's purely for image. It's meant to communicate "Slugline is so creative and forward-thinking that they don't even need non-beanbag furnishings!", and contrast against the Post's button-down, cubicle hell style.

The sad part is that some people see things like that in TV shows and try to duplicate them in the real world, without realizing that devices that work to communicate something on television don't necessarily actually work for doing the thing that the TV people are supposedly doing.
