The master command chair: I bought this at Staples. It's supposed to be rated for an 8-hour day. But after awhile, that seat wasn't so comfortable anymore.
So I had to find something that would make those editing hours easier to deal with. So I found this soft but firm seat cushion, the Wonder Gel Seat Cushion:
But what about that editing? It's easy with this three-screen setup: the laptop plus two external monitors:
A different view of the monitors and the keyboard:
The Fellowes Tilt N Slide Keyboard Manager was the answer to my desk dilemma: how to get a keyboard that didn't need to be screwed into my desk but would be able to tilt for ease of use. This adjusts at three different levels, and has a sliding pad for the mouse. It's so much better for my wrist and arms. Bonus: very Star Trekky.
And best of all, it just screws onto the desk shelf.
What I'd really like someday is a multi-screen setup like this:
But those are just dreams for now...
