We bought one new in April of this year and quickly found out that the queen size will not do a queen size quilt because the carriage, stitch regulator, clamps, etc. take up some room and the entire width of the rod is 96". That only leaves 6 inches total. You'll need that much for the extra fabric on the sides. The website says it is 100 inches - that includes the wood on the legs. Also, I would highly recommend purchasing the new clamps on their website. We will probably buy the king size extension - I have 3 queen size quilts that I can't do without it. We haven't tried to move it or tear down/reassemble yet. If you have the room to set up the king size, I'd highly recommend doing so - it will save you some grief later. I know I didn't offer much help with the current problem, but may the few extra tips will help someone.
