How do feel about adding chairs with a pop of color/pattern?

This coffee table fits the leg style of your sofa and matches the angles of your dining chairs. The frame helps keep the space open.

Find a large contemporary abstract or landscape painting. Pick the strongest color from that painting. Since you have a neutral gray, I'd choose a painting with yellow or blue. Then find 8 yellow or blue throw pillows for the sectional.

Pattern pillows may work, but to many different pattern pillows will make the sofa look to busy, so stick with one pattern design.

I'd choose a large rectangular ottoman for my center coffee table. This is if you'd wanna plop your feet up and watch the game.

All items can be purchased at Ross, Home Goods, or Tuesday Mornings stores.

Hope this helps
