Built in work benches, what have you done?
My upholstery shop does have movable benches & it is in another room.
This room will be the machine shop. Drill press, arbor presses, vices, taps, dies, parts washer, etc. No need for oil & guts on the upholstery this way. :-)
The only 'wheels' in this room are securely mounted.
To the wall. ;-)
