Good to allow desk chairs to roll easily and save carpet wear if you’re in a carpeted room. If it appears warped when originally purchased or delivered, allow it to flatten out in a warm area for up to a day or two before using.
Purchased the chair mat 46”” x 60” to protect our recently installed LVP. Wife uses a desk in the sitting area of the master bedroom. Chair floor mat looks good and working out well.
The floor mat came in a timely manner. However, it has only been a couple of weeks and my chair is stuck in the imprints, that the chair has made in the mat. This is very annoying.
