Only just remembered. The 'fitted' nature seems more appropriate to a
chair than a standard 'loose' one.

One problem with those is they only distribute to load over what is a
small additional area. They will still cause most carpets to develop
crushed pile which, with an office chair, will eventually form a compete
circle. I've used them with other furniture and they still mark but
less obtrusively than the castors they house.

What I've done is to use a replaceable cord runner carpet under the
chair and have a wooden board under that to spread the castors' point
load over the main carpet area. It's worked for me for the last few
years, compared to the dents caused by other furniture - and it doesn't
look too bad either, defining the "office" :-) Much better than those
large, interlocking rubber "tiles" sold for the purpose.
