Product #: 17400065

Made in USA and made from ultra-thick PVC this mat is suitable to use on carpet with underlay up to 30mm total thickness. On all sides of the mat are edges which are slightly bevelled which make entry on and off the mat easy and also prevents people from tripping on the mat. The mat is held securely in place with a number of small grippers on the underside. These hold the mat into position and prevent the mat from moving as you move around.

Made from pure extruded PVC which does not have additives like budget mats do, this makes the mat safe to use in confined space and does not have a strong odour like the cheaper imitations. Because the mat is made from Pure PVC means that the mat has a very clear finish to allow your floor coverings to show through.

Note:The flexible PVC is designed to prevent cracking and can cause indents from chair castors in the mat which will dissapate after use and are normal especially in hot weather.

This mat can be cleaned by using a cloth dampened with water, full instructions can be viewed in the cleaning instructions tab.

Like all of the Mat Shop Chair Mats, these are delivered flat ready for immediate use.

The Underlay that we refer to is a foam layed 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.

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