RevTime Treadmill Mat 6.5'x3' (78"x36") Heavy Duty Fitness Equipment Rubber Mat Black

Works good as a computer chair mat!

I purchased this to put under my elliptical machine in my exercise room. It did have a strong smell for the first week or so but has since almost disappeared. I think you have to expect that there will be some smell but it is totally tolerable. The important thing to me is that it provides protection between the elliptical machine and my flooring.

Just getting set up in my exercise room but so far I love the weight and durability of this mat.

Just rolled it out few days ago. So far so good. No complaints. Fits large work out machines like rowing machines. It's quite thin, I'm worried it may not be strong enough for the long run for protecting cherry wood flooring from heavy rowing machine .. but no complaint me yet.

Better than expected; does have mild plastic like smell; good density/thickness; just wish it were a little bit wider (maybe 3 inches more); length is perfect. Using it over pergo wood finish floors. My treadmill is old and weighs about 300 pounds (norditrack zs, see pictures of my set up).

Evidently I am the unlucky one, because this mat had a big seam through the middle of it. End of one run of rubber, start of another. Looks bad, and a guarantee that's where it will rip. Also, why would they use scotch tape to secure the rolled up mat? When removed, it leaves a sticky residue that is hard to remove. So many other option, sticky tape is not a good solution. Disappointed.

Easy to cut and store.

2 weeks later it is still off gassing and it is too cold to open the windows and air out the room. I suppose some other products could be worse.
