Where can I try active office chairs?

Just as it says, does anyone know where in the Houston area can I try active seating?

I moved from the sales floor to the office this year and the lack of movement has started to take its toll. I have been looking at active seating online but it seems like no one has them on display.

If anyone knows of a place where I can try/buy them, awesome. And if you don't, thank you for reading this far anyway.
