Why is it, no matter where the builder puts floor vents they’re inevitably in the way? This upstairs family room has two vents. One is behind the loveseat in front of the large window, and one is right below the large sofa. Our previous sofa had a little room underneath, enough to slip an extended vent deflector to direct the heat out the front. This sofa is much lower to the ground and has to be moved away from the vent to allow for heat and a/c to get through. A simple shelf was created to remedy this problem since it made no sense to spend money for a sofa table you wouldn’t see anyway.
This will be the quickest tutorial you’ll ever read.
