I remember an old TV show, probably early 80s??, and I remember this white room where the main character would end the episode by laying down in like a floating bed/chair. I think he actually floated above it with nothing below. I believe it was a modern day setting and he was more of a tech wizard than anything else. But I've had this image stuck in my head for years and I yet to come across something that fits.
For some reason this triggered a memory of "The Wizard" from 1986.
