I have both the large and small Ikea adjustable tables. I use the large one for my cutting table, and the smaller for my sewing. I've not tried sewing standing up, but I have the table adjusted so I don't have to hunch over to see what I'm sewing. The smaller table is about 27" wide and the machine has to sit rather far forward, and I notice a bit more vibration because of that. Not enough to be bothersome though. However some machines may cause a lot more vibrations than my Juki 2010 does.
I do love the extra room I have behind the machine, I don't like stuff falling behind and piling up around my feet when chaining pieces.
We've brought in people to help with ergonomics at work. So I've used what I learned there to apply to my home situation. I also have a long arm, and raised that up a bit more than was is "recommended".
Part of my problem is my eyesight - I was hunching so I could see better.
