Went to Staples to look at chair mats. Had great customer service from an employee who helped me with picking one out and then ordering it. It arrived today and it’s exactly what I needed! Thank you Staples!
This mat is is the right size and better than some less expensive ones but my chair wheels dent it. It can be hard to move the chair as the wheels get "stuck" in the dips they make into the mat. The chair is also a Staples chair so it should not be a compatibility problem. The bottom line is I recommend finding a different mat one that is not as soft as this one.
I wanted a basic pad under my chair for my sewing machine and didn't want to pay much so for that reason I should give it a 5. Plus I wanted to 'trim' the plastic and needed to be able to do that myself (which worked out great). However the soft nature of the plastic shows indentations where I've been sitting so I'm wondering how long with pad will hold up so I brought the score down a notch. Not sorry with my purchase; just wantk people to be away of the problems when 'going the cheap route' (Had I not needed to be able to trim the lip part that goes under the sewing machine desk I'd have bought the better one.)
