It helps a lot to get one of the clear plastic mats that are intended for this purpose.

Those mats crack, and are landfill material.

Don't waste your money on those. I bought two, and gave up.

*******

Find a thicker, more resilient surface. I roll over
wood products here, picked for the task. Even wood is
not perfect. The wheels beat the hell out of any material
they meet. I'm on my second wood solution, the first one
becoming too rutted to work any more (the wheels get stuck
and the chair will no longer roll freely).

My protected carpet area is four feet by four feet. Yet,
the solution is not a "half sheet of ply" either. There
are separate pieces of solid wood involved, and L-cross section
Al strips to join the ends. (The strips recycled from another
project.)

Even if I were to stick floor tile of some sort on it,
the wheels would still beat the solution to bits. The
chair "rides like a tank" and the pressure points are
devastating in the long term. You almost need sheet
titanium for the job.

If the office chair had an "air bearing", and you had
a thin sheet of airtight material for it to ride on,
that would solve the pressure-point problem. The "Puck"
can have the air supply, or the "table" can have the
air supply. The smoother the table, the less volume
of air needed to make the bearing. You can see in the video,
the size of motor used to carry a flimsy puck.

(Air hockey table - you can turn down the sound track :-) )

https://www.youtube.com/watch?v=PJr1rLq0IrE

And that table isn't the fastest one of those I've seen.
The puck on a good table, has high velocity.

I have also switched from them - but to laminate. We were pleasantly
surprised not to t find the edges a trip hazard. And I round the visible
corners in an attempt to show I'm not a total slob :)

Depends on the quality.

I am notoriously hard on chairs, wheels and carpets. My mat is very good,
and it is 17 years old. In daily, heavy use.

I think it depends on the mat. The one under me as I type is still in
perfect condition after 14+ years. Alas, not sure where it came from -
might have been Viking.

Mine is from IKEA, maybe 5-6yrs ago. It needs turning over and
rotating around every few months or so and it's overdue being done now
so the back edge is lifting a bit.

No signs of cracking.

Not if you buy good quality ones. I've had the same ones for many years.
