I discovered the perfect footrest for under my desk at work so I want to share with any other moms to be who sit at a desk all day.
As part of our living room furniture at home we have an ottoman set like this, with the little collapsible storage cubes: http://www.walmart.com/ip/Faux-Leather-Storage-Bench-with-4-Collapsible-Ottomans-Espresso/14044579
I brought in one of the cubes today and it fits perfectly under my desk and is just the right height for putting my feet up while I'm working. I know you can buy just the cubes pretty much anywhere, and they're generally pretty cheap if anyone is looking for a good footrest solution! And then it's still useful afterwards back at home.
