Very pleasant to roll and smooth.

I have a nice IKEA chair for my desk, but the plastic rollers and the laminate did not tolerate, I've even ordered them Topstar castors for hard floors.
The diameter of the pins is the same as with the IKEA-rollers, but the pins are shorter by about 1cm.
Nevertheless, the roles fit perfectly into the chair and sit rock solid.
I can now literally glide over the laminate, both from the feeling as well as the acoustics.
The wheels are designed for laminate definitely worth your purchase :-)
