I'll definitely enter YC with some of my ideas at least ready as initial prototype (writing this using the moment). I hope I will like it so to make something similar in future to save this state of startup-spirit.
Chairs would probably turn into a fiasco, but are more comfortable, even the cheap white foldable kind.
I've had it for about 5 years now. I like the size of it and it's surprisingly sturdy, but I'm not overly fond of the glass top, because it's so hard to keep clean.
Been using it for the last 6 years. Works great.
