It has a solid chair pad under it so it will move around easily. It’s a good setup.
None of that actually matters though. I still have to use it as a fixed position chair. I can swivel it to get up and down, but I don’t get to roll it. Every time I sit down to work, whether I notice or not, the little one glides in behind me and wraps herself around the wheels of the office chair to sleep.
I’d rather use a chair that won’t move than startle her, or worse.
