Thick & sturdy.
Color: Blue
Great mat! Nice thick, sturdy foam! -- Im using it along my raised garden beds so I can crawl across the area that's covered w wood chips to work. I cover up lumber edges w old staples with one edge too, and can push myself up & slide it along beneath me. Great on my knees and elbows. Eliminates the need to constantly get up & down. Nice thick, sturdy foam! Gets slippery fast if I hit it w the hose!

Durable and Comfortable Yoga Mat That Lasts
Color: Red
The BalanceFrom Go Yoga All Purpose Exercise Mat has proven to be a long-lasting and reliable piece of equipment. After seven years of use, it still holds up well, showing how durable the anti-tear material really is. The thickness provides great cushioning for yoga, stretching, or floor workouts, making it comfortable to use on hard surfaces without slipping.
The included carrying strap makes it easy to transport to classes or the gym, and the lightweight design is convenient without sacrificing support. Even after years of use, the mat remains easy to clean and hasn’t worn down the way cheaper mats often do. While the surface may show some signs of age, the overall performance has stayed strong, which makes it an excellent value for the price.
Pros: Extremely durable even after years, comfortable cushioning, and convenient with a carry strap included.
Cons: The surface can show wear over time, it may feel bulky compared to thinner mats, and the texture may not suit those who prefer a firmer grip.
A dependable yoga mat that lasts for years while staying comfortable and practical. For anyone looking for a durable, affordable mat, this one delivers excellent long-term value.

From a Non-Yoga enthusiast
Color: Purple
The first time I bought a Yoga mat, I plucked it out of the bin from either Ross or TJ Maxx. Then, I decided it wasn't for me and I sold the mat. So, I wouldn't know how to pick a good mat if I fell over it. I came here and purchased this one from the reviews. Again, I'm not a die-hard Yoga-er? Yogi? So I'm probably not giving it the "workout" it needs, but here's a few things I noticed. When I unrolled it, it was nice and tight from it's position. I had to lay it out, then lay on it to get it flat and ready to use. My dog was amused by this, but I'm not sure it counts as a position.
It does dent. I've seen where others tear, but so far, mine hasn't yet. But dents? Yes. I can see this as more of a "when" rather than "if." The foam is soft-- it's bound to happen at some point.
No noise noted. No squeaking or shifting, or "fart" noises. You can go about your routine in peace.
I did notice a smell on my hands after. At first, I wasn't sure what it was, but it was latex-esque or plastic like. I didn't notice this during, but I did smell it after.
To me, it's squishy and comfortable. Like I said , I briefly used it as a make-shift cot prior to it's official use, and I thought it was fine. Didn't move, and for what it is, I thought it was pretty thick.
I Love the strap, I love the color, it'll do for now. Until it falls apart, I'm happy with it.

Squishiest impact absorbing mat I've seen
Color: Red
The size is smallish, and well advertized at 24" X 71", however the quality and padding is there, and at the price point I know it's a winner. It absorbs pressure and rebounds swiftly. It has a matt texture that is a bit grippy, which I prefer. I've paid a lot more for mats that didn't have this shock absorbing performance. I'm excited to own it.

1/2” yoga mat. Great quality for the money.
Color: Aqua
I bought this yoga mat primarily for the 1/2” padding. I like the color and appearance with the ribbing on one side. I’m an older person and it’s difficult and painful to get down on my knees. This mat is comfortable and so easy to use. Doing my stretches and yoga are so much easier for me.
