I got size 0.25" H x 60" W x 48" D - the largest chair mat available. The hardwood floorboards under the desk in my husband's home office were beginning to look stressed, so I ordered this to protect the wood. It was a little pricey for us, but I wanted it to be large enough so he wouldn't feel constrained, and I wanted it to last forever. (I could actually have gotten it cheaper from two other vendors, but I didn't trust them as much as I trust Wayfair.) I also got the Three Year Protection Plan that was offered because, after reading many many reviews from ALL the top makers of tempered glass chair mats, I could see that VERY occasionally, for some unknown reason, a chair mat from might suddenly just shatter (usually within the first year or so), so I got the Protection Plan to calm my fears about that. Anyway, the mat came beautifully packaged and was in perfect condition. (It's VERY heavy.) Anyway, my husband is delighted with it, thinks it's beautiful, and says it's fun to roll around on.

Excellent quality glass mat for my office. The beveled edge is nice and seems extremely durable. It was shipped quickly and the packaging was great. It makes rolling the chair on carpet a lot easier.

I absolutely love this chair mat. It was very heavy to move and it was delivered with lots of packing and foam protection. The beveled edge allows the chair to roll off and on and it is very thick glass. I am looking for another area I can use one, I like it that much!!!

This is thick, sturdy, heavy durable glass and I’m really impressed with the quality. I’ve seen much more expensive versions which really don’t do more than what this glass does. It even arrived with a letter as well as felt stickers pads in case it’s used on hard flooring. Super pleased!!

I got this to protect the oak floor in my office, especially since I’ve been workin from home the last couple of years. The mat is heavier than I anticipated it would be, and I wish I had known it shouldn’t be used near metal desk legs, but it worked out and looks nice. The weight of the mat made it kind of difficult to install.
