Product #: 123456789

Made in USA the Medium pile heavy duty chair mats are designed to be used on carpet with no underlay with a total thickness of 12mm or less. The surface is a smooth transparent finish is ultra-clear as the material is extruded twice removing any impurities and imperfections. On the underside of the mat is a series of grippers designed to hold the mat in place on carpet and prevent movement while in use. These grippers are a special design to prevent piercing through carpets to eliminate damage to your existing floorcovering.

These chairmats are made from pure PVC that is twice extruded to remove any impurities making the mat more durable. The material is free from plasticisers that contain harmful elements making the mat safe to use in rooms. By not using these plasticisers the mat has a far less odour.

Being a smooth surface makes the chair mats easy to maintain, for detailed instructions please visit the cleaning instructions tab.

This option is suitable for use on carpet without underlay up to 12mm.

The Underlay that we refer to is a foam layer under domestic carpet to give it a nice soft feel. When carpet has underlay it gives an extra layer of softness and when you sit on your chair on top of a chairmat there is more chance for the chair mat to crack as the wheels depress into the soft surface, hence the chairmat needs to be thicker to prevent the cracking.


We do not recommend this for use in a home. If you are using this mat in your home, you will most certainly have underlay under your carpet and require the thicker mat which is designed for Carpet and underlay.


You can also check the depth of your carpet and underlay using the instructions from our video -

If your carpet is >12mm you require the Heavy Duty Chairmat for carpet with underlay

In a commercial office with carpet tiles and no underlay <12mm can opt for the Heavy Duty Chairmat for Carpet without underlay
