I ordered two of these for use with the p90x system because there's a lot of ab work done on the floor that just isn't comfortable on hardwood. For 18 dollars each I couldn't ask for anything better. They are thick and cushy and don't slide around on my floor. I don't really do yoga, so not sure how they'd be for that.

This mat it well padded and is easy to roll up and strap together for transport/storage. When I first got it, it had a strong plastic/rubbery smell which I think is starting to go away after leaving it out and using it a few times.

One thing to keep in mind...
This is not what I would consider a yoga mat, it is made from rather thick foam - probably like 3/4". As a result, when it is rolled up, it creates a cylinder 2 ft long and about 7 inches in diameter. So if you want a mat for yoga classes or to take to the gym with you, this mat is probably a little to bulky to be transported easily.

I need a thicker foam mat for my Physique 57 workout videos, and it generally serves it's purpose. However, it doesn't lay out flat which can be a bit annoying.

I got this mainly for doing the Ab-Ripper X from the P90X series and it works perfectly. I do use a beach towel over it as I just wanted the mat as a cushion for my back. The size is reasonable and works as intended. I have used this for more than 6 months and it is still in good condition.

I originally bought this mat to practice sitting in the seiza position to be able to sit in that position for longer durations. Since it is 6 ft long I can fold it in two and add extra cushion. It was an excellent buy at an excellent price range.
