Welcome to the Quilting Board!
I actually like the arms on my rolling chair!
You need to have excellent back support when sewing at your sewing machine. That is what is most important !!
A Good Friend, like an old quilt, is both a Treasure and a Comfort
I used an exercise ball and loved it! until I rolled right over a dropped pin. Now I am back to my armless rolling office chair...
When it comes to furniture for quilting, I like to find and buy the best quality that fits into my budget and ergonomic requirements. It is important to consider long term orthopedic issues. I feel this is an investment in my future health, with bonus of (hopefully) keeping me quilting longer. Then maybe I'll get those UFOs done.
I finally got a chair. A rolling office chair from staples. Some of the chairs there could be put together without the arms and some could not, because the arms were holding the seat and back together. I got one that could be put together without the arms and my 14 yo son put it together for me while I was running an errand. What a nice surprise that was to come home to! It's a bit short though, even at the tallest setting, so I put a thick cushion on it to boost me up a little.
I move far too much not to have a chair that scoots around the room. I'm set up in a U so I really need it. When I sew in the kitchen though, I use a non rolling chair but it does have to swivel for quick leaps to the ironing board. :-)
I like my new chair but I don't like having to use the cushion. It feels unsteady. So I'm going to order some giant wheels for it to replace the ones that are on it. I have 2" wheels on it and I can get 4" ones. I think the extra 2" should help a lot. Also the new wheels will be more suited to my hard floors. The ones on it now say they're best on carpet.
