I have a Janome 1600 and a metal frame that I put together at it's full 12' length several years ago; then I had to dismantle it when my son came back home to live and took over my 'frame space'. Construction and de-construction of the frame was do-able by myself; I can see very well up close and am quite limber, so getting down onto the floor and back up again (many times!) was not a problem. I have the manual downstairs, but have to go get ready to go with hubby to his doctor's appointment, so I will check back here this afternoon and can perhaps answer your question re: the legs.
