Herman Miller and spinning

What do they have in common? The chair that Herman Miller made is very stylish and it spins. Fun for any kid with SPD that requires a spinning diet. My hubby and my dad went out to purchase the most comfortable office chair at POSH. It is around USD 1000+. I almost floored when I heard the price. But at least we have something for Clemmie to spin around in and also for her to push me around in.
