I have a special fondness for accent tables. They are naturally suited for being "design ambassadors"- their small size allows them to represent a foreign style in your home without causing a major clash. (Just last week we explored introducing a MCM side table into a traditional setting!)
However, due to overcrowding, I have solemnly sworn not to exceed the current population of accent tables- I shalt not add, only replace.
Good thing I found a loophole. If you don't have room for a table... call it an ottoman.

Did you recognize it? The frame of this side table had a very elegant shape, but wasn't really a table at all without the top! Rather than simply replacing, why not repurpose? You'll only need a circular piece of plywood (cut to fit), your choice of fabric (I'd go with a bright green velvet or damask), a handful of buttons and thread, and a staple gun! Because the finish was "shabby" (read: really really ugly), I also opted to give it a coat of always lovely black glossy paint.
What a practical piece of furniture this would be! If you chose to put it in a living area, it could serve triple duty. It has a plush seat, a shelf for storage, and, with the addition of a cute serving tray (like so), it could get back to its roots as a table!
Personally, I'd love to see it in my bedroom, where it would mingle quite nicely with its compatriot vanity desk. $15? C'est possible...
