You burn more calories throughout the day," notes Jim Gattuso, owner of Akron, Ohio-based Amish Country Furniture Sales, which sells custom-designed office furniture such as the stand-up desk owned by [Lawyer G. Stewart Webb Jr.]. According to Mayo Clinic researchers, employees who stand at their desks burn 10 calories per hour more than their seated co-workers do.
