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.

This 102" Supermat is a good quality mat that is the perfect size for the Concept 2. It is not overly thick but plenty sturdy and durable enough for home use. It lays flat right out of the box and I do not have any problems with the rower moving around. I use it on a berber carpet with no issues. For $60 shipped you cannot go wrong.

After lots of research, I purchased this pad for use with a Concept 2 Model D rower, the newest version. The rower sits on rather premium carpet that I wanted to protect during workouts. I would highly recommend this accessory. It is long enough to accommodate the rower, I get no slippage during heavy workouts (both the rower and pad stay in place), and there is no "bunching up" of the pad on the carpet. I am 6'1 and weigh about 220# and still there is no movement of the pad in relation to the carpet or the rower. Finally, It's thick enough to provide adequate protection. I've purchased 100s of items on Amazon, always study the reviews to guide what I buy, but this is the first review I've submitted, so pleased I am with this product.

There's not a whole lot to say about this. It's a rubber mat that serves its purpose well. It's heavier than I expected it to be, which is a good thing--you don't see cheap AND heavy mats. The only reason I didn't give it 5 stars is because it needs to be a little bit thicker. This is mainly just me being nit-picky, but I try not to hand out 5-star ratings unless they're truly excellent in every single aspect. I'd give this 4.5 stars if I could, but alas, half-stars aren't an option, yet, so I rounded down ;-). I check email several times a day, so if anyone has any questions, I'll answer them ASAP.

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!

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 use it for rowing machine LifeCORE R100 (can also be used for Concept2). Very good quality product. In fact it is much better then I have expected. Also note that it is heavy (over 30 lbs). It stays in place during my rowing exercise. You can buy cheaper mats, but don't expect the same quality as Supermat. Also note that Amazon has the cheapest price ($39.99 shipping included) compare to other websites who sell that product. 1/7/14 update Its's been more then two years since I purchased the mat. I still don't see any negatives and I still like the product. When I purchased the mat, there were no reviews posted yet. I took a chance in purchasing this item and it was a good choice. Price went up since I purchased Supermat two years ago, but it is still a good value considering a good quality of the product.
