Switching from plastic to glass mat was one of the best buys in my life!
Highly recommended for those who are annoyed about crappy office plastic mat protectors that constantly crack on their carpets.
Herman Miller Aeron chair + glass mat = zen
Like a lot of folks I was like "NO WAY" I am putting glass under my chair, but after having this for awhile, I can safely say this will be the last time I buy a chair mat. I've dropped all sorts of heavy objects on it and its never cracked. One of my other incorrect assumptions was that it was going to be be heavy asf. Nope, it was actually very easy to carry.
I even considered getting pool glass from Bunnings, but when I saw it in person, it was about three times heavier than these glass mats.
I've now ditched all my plastic carpet protectors at home and in the office for this one.
Overall 10/10 buy and I don't say that lightly.
