On Thursday M & I pick up our new dining room chairs. I suppose they would be considered our first piece of grown up furniture, meaning they aren’t from IKEA or a hand me down. We decided on two since our dining room, while spacious for your normal apartment in Brooklyn, is really not all that large.

Very nice urban look!
I suspect that your slow entre into ‘adult’ furniture has more to do with the pain of getting things into your place than your love of all things IKEA.
