Vitrazza carries 5 sizes of Glass Chair Mats that include a "Tab"—a 6" x 23" bump-out on the front of the mat. A tabbed mat is designed for use with a desk that has the traditional 24"+ opening between two drawer pedestals. See this example below left.
The tab is notched out of the mat in order to wrap around the drawer pedestals and extend 6" under the desk. That extra 6" is intended to keep your chair casters on the Glass Chair Mat, if and when you work close to the desk. Approximately 80% of our customers find that they don't often sit close enough to the desk where they require a tab. In that case, one of Vitrazza's square or rectangle shapes will work just fine.
Now, if your desk is completely open between the left and right leg, either because the drawer pedestals hang and don't go to the floor, or because there are no drawer pedestals, you definitely don't need a tab. If you'd like some of the mat to extend under the desk, you can simply slide the front of a square or rectangle shape under the desk. See this example below right.
If you have an L-shaped desk (desk/return) and want a tab on one or both sides, take a look at the designs we can tailor for you on our Custom Designs page, Click Here.
There is a price premium for the tabbed mats, so you want to be sure you need the tab before you choose that more expensive option. If you're wondering why there is a steep premium between a rectangle mat and the same size with an extra 6" tab, we outline that for you here:
First, of course, there is the extra material.
Second, the fabrication of the notches requires finishing by hand, which increases the cost.
Third, our packaging for tabbed sizes includes significantly more protection.
And finally, we incur higher freight shipping costs (vs. ground shipping) for 4 out of 5 of the tabbed units. Continental US shipping is FREE to Vitrazza customers, but the cost is built into the price.
