"Not the Comfy Chair!"
This is the final special sitting day of the year. Use it wisely.
On Living Room Chair Sitters Day, you probably have several types of chairs in which you can sit.
The davenport doesn't count.
It doesn't matter whether you choose to sit in the rocking chair, the recliner (recliner/rocker), or card table folding chair. Any of them will suffice.
What you do while sitting in the chair matters more.
Since it's the middle of July, you can't watch live (American) football, which is a bummer. There are plenty of other lesser sports you can watch on TV though. And if this is a summer Olympic year, there are probably some trials going on.
Other than that, there's not much worth watching on TV from your chair. You're better off reading a book or taking a nap.
