I suggest something like this that parallels the WIC wall. Note the additional storage under the bed. The surrounding "wall" is simple lathe that is whitewashed.

Here is a versatile stacking coffee table that isn't too large. Can serve as a dining table for two.

The more multi-purpose furnishings the better. Here's a folding cart that is useful in the kitchen. It is only 16" deep so it could tuck away in the closed when not in use.

Back in my misspent youth I had a similar studio apartment. I separated the living area from sleeping area with a line of bookshelves. I put the TV on a swivel so that I could watch from the "living" area and the "sleeping" area. I had a sleeper sofa in the "living" area that could be let out for guests.

The sample picture showing the bed with storage underneath and the faux wall is really cute. I'd consider something like that. You might also consider a sleeper sofa for guests or those folding cube chairs that make into a single bed.

These are amazing suggestions! Thank you so much!
