I started sewing standing up about a year ago and it's so much more comfortable that I can't imagine sewing any other way now. I have a big 1 inch thick pad that I stand on to protect my feet from my hardwood floors. My Juki 2010 has a knee lift but it's in the box and I've used it one time I think when I first got the machine. The foot it came with has the perfect scant quarter inch for piecing so that's what I use. The feature I'm addicted to is the clip threads button, I had out my DSM last week for the zigzag and I had to clip thread with scissors!!
