Sleep Number by Select Comfort offers the now famous, Sleep Number Bed as well as other specialty beds, pillows and bedding. So what happened to the originator, Robert Walker? Since inventing the Sleep Number bed in 1987, which can adjust the comfort level of the mattress to your own liking, he has been busy designing a system called devolitization that superheats coal without burning it in a sealed environment which prevents carbon emissions from being emitted into the air. Soon you will be able to sleep comfortably <em>and</em> not worry about carbon! They are located in the upper level of the Westfarms Mall, by Macy's.
