I’ve bought my share of those crappy chair mats they sell in Office Depot. They never really work well, and they are a bear to move around. I thought there had to be something better that wouldn’t deform under the weight of the chair when you put the chair mat on carpet.
I had some leftover old Pergo engineered wood flooring I wasn’t using from an old home improvement project. I snapped together 4 pieces, to create the perfect chair mat:
Best part about it is that it took 2 minutes to snap together the flooring. If I ever have to move it, it’ll take a minute to break down.
(I understand I’m not the first person to think of this, but it felt good to solve this problem with materials I had lying around. If you don’t have some spare wood flooring lying around, this might make less sense…)
