This question is regarding under bed storage. I have a new King size Temperpedic bed which I love. In order for me to utilize space under the bed I needed to use the cones that lift the frame so that I would have enough clearance for my containers to fit. However my problem is now how do I move the bed in order to make it as it fits closely into a corner of the room and the casters no longer roll since they are now on cone-shaped blocks. Do they make bed frame extensions, or cones, with wheels?
