Frequent local Salvation Army stores. There are low, low priced sofas at times.

Are you planning on painting all the walls or the one just behind the loveseat? I would pick a cream colour similar to what is in one of the floor tiles if you're painting the whole room. If you are only painting the one wall I would just continue the same colour as the other walls. I think your coffee table already matches your sofas - there are products that can easily make your table look like new. I use a product called Trade Secret scratch remover, but there are other brands that would work. I would be on the look out for a larger square or round table to fit between the sofa and loveseat. I would then be on the look out for a larger picture for the wall and then get a few pillows and a throw in a colour pulled from the picture.

Duplicate post. (On her other post, she has ignored advice to change the clashing wall color.)
