Read All Rubber-Cal Elephant Bark Rubber Flooring Rolls - 3/8-inch x 4ft Wide Rubber Runners - Available in 6 Colors & 13 Lengths-US Made Reviews

Not must too add about a rubber mat. It's fairly rigid as opposed to soft. A little hard to cut.

Received the roll 1 day earlier than estimated - Good. After unrolling, placement and evaluating it, decided that I needed a 2nd roll. But when I went to the site, the solid black color was unavailable, at any lengths. Turns out that once an item is out of stock, it's unknown when it would be restocked - Bad. So, I'm stuck with an incomplete flooring job that will have to wait. Which is why I went across the board with average ratings. I did not want to out-right order both rolls right out of the gate, not knowing if it was going to work for me, but I also can't fault the product either. This flooring does not give, so it should stand up to exercise equipment nicely, but might be hard on ankles and knees if one was thinking of doing aerobics or jump training. For what I wanted to do, exercise area in the basement (concrete floor) for a bike trainer, solo flex and weight/band stands, it should work out fine. If I ever get it finish and in use, I'll see if I can add to this review.
