Your furniture is playing "the rug is lava" and the coffee table just died!

You have a lot of big furniture in this room, so I'm going to recommend letting go of most of it. I hear you on the sentimental sofa. I have some pieces like that, so it'll stay put. Figuratively.

Literally, I recommend turning your mum's sofa so it faces the fireplace. I love your wingback chair, and it goes great with the sofa, so let's keep that where it is for now. Let go of the rug, and let's look for a coffee table that suits the style of the sofa and chair, rather than what you have now.

So far, we're just keeping the sofa and the wingback chair. You with me?

Let's move the sofa table behind the sofa, that way you can keep some reading lights/task lighting.

Next, we're going to remove everything from the walls. Yes, everything. This lets us see how the room looks without the distraction of frames and photos. Then we're going to curate the art and photos to create a collection that goes together. The other pieces can be distributed appropriately through the house.

Once that's all done, post another photo so we can offer continued advice.

Are you keeping your mother's sofa as is? If so, use it as a starting point on which to build the room. You definitely need a bigger rug. How many people would you like the room to seat?
