I personally would hang either one large photo or two photos above the bed (2/3 the width of the bed frame). I would also hang curtains on either side of the window to make it more cozy.

I bought a big fluffy white comforter for our bed because it reminded me of a sheek hotel. Then it’s easy to add pillows or a throw blanket to add color and/or textures.

I would turn that corner with the chair into a cozy little corner. Maybe add a floor lamp to hang over the chair and add a tiny little table next to it to set your coffee or book.

Its hard to tell what color/style your dressers are but I would get your nightstands in different colors than the dressers so it’s not so matchy. Maybe mirrored, navy or a dark gray nightstands.

Love those suggestions! Would it be too lamp-y with another floor lamp next to that chair Since there’s a lamp so close on the nightstand?

Maybe a plant Instead of a lamp if you think it’d be too many lamps, but I think as long as the lamps are different styles/shapes it wouldn’t look too lamp-y. Maybe since the ones on the nightstand have a larger white shade you could get one that has a small metal light fixture top.
