The black leather sofas are the ones we currently have, but the modern one is in the family room. The antique one is currently in formal lounge, but we are not necessarily planning on keeping it… I am so complicated, aren't I :(

I say “no” to the table because it is just too much of the same shape as the couch and the media stand; because the top is not the bright white; because the frame is so industrial and your sofa is not that look. Consider the feet of your sofa.

You wont find Ann B here- this is where you post a design dilemma

I would rethink both the tv cabinet and coffee table as along with the couches they are too heavy for the space. You need to get some light underneath them rather than the solid shapes. Currently they stain is too red. Glass is ok for tables but it can be difficult to keep clean with children in a home and having something all glass would highlight how heavy the couches were. The combo of a timber top and the iron base is good for the coffee table You could possibly paint, restain or oil the cabinet to match the table. Alternately they could be painted and used for storage in children bedrooms rather than discarding. I would work on getting some texture into the room and a lighter rug would make difference to the overall look. Go brighter rather than lighter with the cushions - and introduce some pattern- they can always be returned if they don't work. Throw rugs might also be cosy. good luck
