This is a very heavyweight mat that does an admirable job of protecting my carpet. My Concept2 Model E rower fits perfectly on the mat, with several inches to spare on the front and back. There's also ample room on each side.Being so thick, the mat would adequately protect all types of carpet, as well as hardwood floors. It's not especially easy to move around, but since I keep it in one place it works just fine for me.Despite using my rower for an hour each day, the mat remains in position with just an occasional area where it tends to rise slightly from the vibration. This causes no problems at all, and is easily fixed by pulling the ends of the mat after each session. The rise is so insignificant that it's not really necessary to do anything, but if you want the mat to be completely flat after each use, just do the above.The bottom line is that this is a superbly manufactured mat that will protect your flooring. It can be used with any type of exercise equipment and is extremely durable.

Great mat. Ultra durable. No rips. Absolutely recommend.

I bought this mat to go with my Concept 2 (model D). My erg fits perfectly on it and, more importantly, neither the erg nor the mat move around during my workouts. I would note that I'm on the short side, so someone of larger stature might generate enough force to move their erg around on the mat (technically you're not supposed to if you're doing it right, but generally the guys at the boathouse would shift the erg at least a little bit over the course of a workout). Anyway, my floors are unblemished; I roll this up and store it every time I use it. It's a little heavy to pick up and unroll every day, but that's why it protects your floor so well.Update 12/2012: I have noticed that the mat does move on my floor a little bit when I'm doing my faster intervals (2:00 to 2:08 split, for your reference) - enough that if I'm doing a lot of faster intervals, I have to get up in between them and move the mat back. I've also noticed this happening more in the cold weather, so I think this also has to do with the amount of friction between the floor and the mat - currently it's lower than it is during, say, the summer. I would still recommend this mat, though - nary a scratch on my floors!

The mat is the perfect size for the Sunny Phantom Hydro rowing machine. It works well to protect your flooring from sweat and wear. So far, the mat has been durable enough to withstand the weight of the machine with a user, and not split or crack at the machine's contact points. This is impressive because the mat and machine sit on top of thick carpet. This mat has worked well for my needs.

Bought this for our concept 2 rower which fits very well, as others have already reviewed. But we temporarily had one end of our elliptical on the side of the mat and even 8 months later there are still two circle indentations from the feet. Was hoping they would go away but look to be permanent. As for the rower, we have the mat on fairly thick carpet and works well. There is little excess length and the rower does move back after a while, but not a big deal.

I bought this mat to go with a Newport Challenge AR rower. The length is great and it's reasonably thin, while being incredibly durable. It obviously comes rolled, so I walked back and forth on it to smooth it out and in not much time at all it was sitting pretty flat to the floor. I assembled my rower and placed it on there and it has worked out great in my living room. I don't have a huge house, so having something that isn't in the way with furniture around it is a real plus. My rower doesn't slide around at all since it's on this mat and it has been great for protecting my wood floors. For $39.99 you can't go wrong on this product. I love it!

I am extremely sensitive to rubber and plastic chemical odors and vapors. I have gone through four other rubber mats for my elliptical machine. All four have ended up in the trash because of their horrible and unbearable rubber/chemical smell. The last two actually gave me migraine headaches after 24 hours. This is the first and only rubber mat I have come across that not only does its job, but also has NO chemical smell whatsoever. It is definitely thick and durable enough to withstand wear and tear from the elliptical. I am 100% satisfied with this purchase and plan to buy an extra just to have on hand for the future!

I bought this to put my rowing machine on, as my rower would move around my hardwood floor when I was using it. This mat works perfectly. It stays in place, doesn't bunch up, and my rower doesn't move around at all anymore. This is an excellent mat for use with rowing machines.

This mat is thick enough to protect the floor, but not too thick to feel like padding. A good fit with some extra room under our Concept 2 rower. Easy to wipe up spills etc.

Stops all the fibres from the carpet going into the treadmill. Easy to clean. Took a while to flatten out though.

Bought this at the same time I purchased my  Concept2 Model D Indoor Rowing Machine with PM5, Gray  - I've concluded it's an essential accessory. It's a perfect fit for the length of the rower. It's substantial in weight, but not prohibitively heavy, and protects my hardwood floors with no skidding around. My only gripe is, as mentioned by others, it is considerably thinner than 2.5cm; this does not alter its effectiveness for my purposes, but if thickness is important for you than you may want to explore other options.
