My messy wall unit

Actually, there is a designer who has designed a sofa/table piece. You can see it here - http://kononenkoid.com/julia-kononenko-projects/convertible-sofa. That may help you visualize your planned project.

We need a bit more info are the wall colors staying, all the art on the T.V wall needs to be gone the 2 floor lamps really do not work together I have no idea what that turquoise thing is on the right maybe a curtain , with waht you show IMO you could go any direction for fabric for the chairs I think they might be fun in zebra print the black and cream one with black foot stools

i agree with Ms. Rupal Shah as to get rid of the piece or redo it. If not you could probably use wallpaper to cover it. if not that even i have a suggestion for colour pallet. the wall opposite no. 3 should also be no. 3 and the wall opposite your green unit can have a custom wallpaper with shade 5, 4, and 2. you could also get a floral mural done in the same combination. Shade no. 1 (Sage) would be perfect for tufted head board for the bed. white bedsheets with large cushions in shade no. 5 (Burgundy) and shade no. 2 (rose pink) to top it off you could have some accessories such as: Dont forget to keep 1 or a few indoor plants too!
