Lovely kitchen. Is that entry closet the only clothes closet? What size futon (single, double, queen?) What other items to consider, e.g. books?

I work from home and am getting ready to need a new office chair. I spend hours every day in this chair and need something comfortable. My current chair is a typical black faux leather job with wheels - but because we are getting ready to put hardwood floors down in this room in the near future, I might want to consider getting a chair with regular legs that I can put felt feet pads on. What features should I look for in a chair? I know it will need to be relatively lightweight, but I worry about sacrificing comfort. I also want arms. I've been searching online and just can't even seem to narrow my scope. Ideas?

The other place I was considering putting the wood chair is here in this super awkward nook which needs to completely change. I was thinking it would be kind of hidden here in the corner though. If I bring the blue chair down here I would have 3 separate pieces of different colored microfiber furniture though. (Gotta love easy cleaning with 9 and 3 year old boys!)

It actually needs to be pretty solid color because I’m doing this pb teen print for bedding
