Seriously? Seriously!

This is a BalanceBall Chair by Gaiam.

The cost is around $100.

Is it beneficial? Sure

Is it going to fly at your office? well... maybe.

This chair allows you to work your core while providing spinal alignment . The trick is to not lean back on the chair's back - that would negate the core work if you place your weight on the back of the chair.

Some testimonials I read regarding the product state that it allows you to keep your posture in check and you are not so sluggish and sleepy after 8 hours of work. So who knows. I want to try it, though!!

The chair also comes with exercises you can perform. Here is one of the stretches:

• Begin by sitting sideways on lower edge of chair.
• Place hands on ball and support bar for stability.
