I'm not sure why everyone says the carpet is a problem. I have no trouble with carpet in my sewing room. We have hardwood in the front of the house (built in 1923) and the computer chair tears it up if I don't have a floor protector covering it.
I considered taking out the carpeting in the sewing room but our house is not on a slab it has a foundation with a crawl space underneath so it gets very cold. And it does double as a guest room (there is a queen murphy bed in the room). I also like how carpet soften sounds in the room. We don't have any pets so I am not as concerned about dirt in the carpet.
