SuperMats High Density Commercial Grade Solid Equipment Mat 29GS Made in U.S.A. for Large Treadmills Ellipticals Rowers Water Rowing Machines Recumbent Bikes and Exercise Equipment (3-Feet x 8.5-Feet)

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.

Good high quality mat. No weird smells, tough and easy to clean. Fits perfectly under a concept2 rower.

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

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.

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.
