The clean lines throughout this living room designed by Robson Rak are making a small but mighty difference. From the white paneled walls to the black-trimmed window and modern angular yet plush sofa, the linear motif is so easy on the eyes. And we love how the green nesting tables bring in some round contrast without clashing. For a similarly calming aesthetic, choose light colors and modern, low-to-the-ground furniture. Then splice in contemporary decorative objects to add personality. And bonus points if your living room has a lot of access to natural light.
