My first long arm had the option of a 5' frame. The frame size was determined by the length of the poles. The machine carriage took up over 6" on either side, so the actual quilting area would have been less than 4'. You need to find out how they determined the dimensions as you may have less than 5' of actual quilting space. Also, looking at the photos, there are no rollers, so the quilt can just float on either side of the quilting area allowing any size to be quilted. With no poles to wrap the backing, batting & top, I'm not sure if you need to sandwich the quilt first, which is a big plus for most long arms. I would make sure you find a video on how the quilt is loaded.
