Many buildings have commercial carpet tiles. They are less expensive when it comes to checking a job, rather than replacing the entire carpet. Sometimes the seams are showing, if you are not careful to install! I've never seen loose.
My office is she following in the month. The common room of the building already. Do they look like normal carpets. I do not see the seams!
My cousin on your way through the basement are. Had fun with a model, as the sum of the treadmill. They were not a checkerboard pattern with texture paint. It's so cool!
Good luck! With pets and children is a good choice.
