I used to sit all day to write. Now I stand for long stretches. I would get a treadmill desk or dummy one up, but we really don't have room until Teen moves out.

So I got a cheap little standing desk on Amazon.
The only problem is that the keyboard height that is right for my wrists means I am continually looking down. I do NOT need another excuse to slouch. I thought about getting an Ikea Fredrik Desk and a separate keyboard so I can have the screen at eye level and the keyboard at wrist level. And then after Teen moves out I could add a treadmill underneath.

Then I saw this standing desk from Uncaged Ergnomics..
I use my laptop at the right height now, with an old keyboard and mouse hooked up to it. I think it is helping me not to slouch.
