This is my Performance 5 with the Junior table. I hope the pictures help. The table extends 6" from the end of the arm and 8.5" from the needle. I also have a larger table that I use here at home but I bought the Junior table so I can take with me to classes. If you have any questions let me know.

Thanks everyone! That's very helpful.

We're going to talk to the office furniture store tomorrow about this project. I want to get their estimate. A few years ago, they built a desk for us to our exact specifications and choice of wood finishes. It was a fraction of the price of a new office desk that was not the size and configuration we wanted. I'm hopeful that I will have the same experience with a sewing table.

If you want one for classes remember not all class rooms have space for the larger table.
I know on someone who was very vocally upset that her larger table was too large for the class room space. Uncomfortable for all around her.

Thanks AliKat. I'm looking at the small one.
