It works as advertised

It is shaped more like a mat that would go under a desk chair. I purchased it to protect my laminate floor from accidents made by my dog. It seems like it will do the job, will be durable - just wish it was rectangular like the description and photos.

Quality product works well and dries quickly. I use this item in a kitchen washing and cleaning area.

These do exactly what they are suppose to so I would buy them again

I recently was asked by a fellow Amazon customer if this mat would work under an office chair where the floor underneath the mat was concrete. The choices yes, don't know, etc. weren't clear enough to offer useful opinion, so I'll put it here.
I think it will work fine, it's too then to be squishy, and be hard to roll. That said, I have 5 of these mats but no rolling chair to try it out. Hopefully this helps.
I still miss my dog but I now understand why anyone could get another dog after going through the heart break. It's simply that there is another dog who needs a loving home.

I took a chance and bought the first one. I cut it to fix the dimensions of my shower stall and used leather punches to make a set of holes that align with the drain.
I have a really old dog, a Grand Pyrenees. This is my first dog so for those of you like me who don't know dogs, she's a big (65 pounds) white as snow fur dog who was used by a back yard breeder to make puppies and then let loose on the side of the road when she didn't. She got rescued by some good folks who took care of her and made her available for adoption. I'll try to get to the mat... her plumbing is shot for both product lines, Chanel Number One, and Chanel number 2. I modified an extra large person diaper that provides containment.
Her back legs give out and when she is laying down she can't get up. Also if she's up and falls to a sitting position, she can't get up. So the number one daytime (and night time) game show at my house is to keep her from squishing the pancake.
When it's I'm sorry you've been a wonderful contestant time, I needed the mat to help keep her from flopping around while I do the wash up on aisle 2 in the shower.
My decade plus in Special Education provided me with the skill and patience for this.
Do not try this at home; I am a professional. But if you insist because you too can't give up on your old dog, let me add one tip. Cut some nylon window screen and put it under the mat. The piece I use is full size and duct taped to the tile under the mat. Dog fur in the drain will cause a clog.
I bought a couple more mats, one for where she falls into her feeding dish and one for the floor just before she heads out to the backyard on the ramp I built. Yes, I built a ramp, of course I did! When the mat takes a ding and curls a bit, I flip it over and it flattens out.
And now a question for anyone still reading this? Why would anyone get a dog to have to go through this heart ache every 10 years? When my large screen TV dies, I just put in the CRV and take it to e-waste for re-cycling.
Anyway....
