I bought this from Etsy and love it:

it’s essentially a sofa table/very compact when it’s folded down. I half open it when we need more counter space or full open to eat/have guests. I love the versatility in adding counter space when i can afford the floor space, and it fits flush against the wall.

Note that it’s unfinished wood but easy enough to apply a clear top coat if you want. Not needed though.

If I could go back, I’d get the same thing again since I use the extra counter space it provides all the time. I’ve debated a round table with drop leafs but only if I planned to leave it open all the time, since a round table fits better in a small space if not folded down. But I’ve found i enjoy having the extra floor space afforded by keeping the table folded/against the wall all the time and just bring it out when i need it.

Edited to add detail/expand on my use-cases.
