How to Decorate around the Television
When the television is to the left (or right) of the fireplace, I like this arrangement of console behind the sofa, and two medium sized chairs which can be easily turned for viewing.
The television is inside cabinetry above the fireplace. Four chairs allow for easy conversation when not viewing a program.
Above, two sofas at right angles. Television,not shown, likely on bookcase to the right.
Below, comfortable arrangement of statement sofa and comfortable high-backed upholstered chairs. Television would be placed above mantel.
