I have a padded sewing stool I put next to me, and one of my cats loves to sit beside me while I sew. I don't have room for any in my lap and use a knee lift so I move my legs around a lot.
When I'm in the office, she also comes and sleeps on the closed sewing machine cabinet I use for a small table next to my desk. When I'm not home, she'll spend time curled up on DH's lap while he's surfing the web. She does prefer to be with me, but knows my lap is not a good place to sleep - I move around way too much.
The other four cats come visit occasionally, and sometimes take a nap, but she's the only one that is pretty much a constant companion.
