Help your guests fall asleep and stay asleep with the naturally soothing white noise of a Yogasleep Dohm sound machine. As the original sound machine introduced in 1962, Yogasleep uses fan-based white noise to create a comforting sleep environment that masks noises which might otherwise disturb sleep. The machine features adjustable tone and volume with a simple twist on the cap and collar, and runs on standard US 120-volt household current, comes with an 8-foot power cord. This is an affordable way to mask noise disruptions for your guests and increase guest satisfaction with your property. The sound machine comes in stylish tan, assembled with sturdy plastic, and is backed by a one-year limited warranty. This item is UL/CUL listed and approved for use in Canada.
