I have a really nice office type chair that my husband got when he hurt his back. It's from the Relax Your Back specialty store. It has all the bells and whistles. He used it at work for quite awhile, but got annoyed when he started having to hunt it down every day. A gal there decided she liked it better. She knew it was his, and why he had a good chair, but she didn't care. So he brought it home to me.
I love it, and use it all day long most every day. It is my computer chair and my sewing chair.
