This looks like a great set up! I bet it will help you so much & it will be easier for you to move around, etc. while you are working, too. (I saw an example of that at the #SportsNerds show tonight lol.)
As I said to you earlier, I am so tiny I can just stand at my kitchen table and use my laptop as if it were a standing desk! LOL! But in all seriousness, you are taking great steps toward better health. Good for you!! :)
