The Dohm Natural Sound Machine has a more modern, streamlined look- we enlisted the help of Michael Graves Architecture & Design which is a noted and innovative design company. The Natural also comes in nursery-friendly colors like white/gray, white/pink, white/blue, white/green, and charcoal. The Classic comes in white, black, tan, pink, camo, and grey. Otherwise, the two machines have the exact same internal components, operate the same, and create the same fan-based white noise you know and love!
