I’m new to stretching and recovery classes, and there is a lot of floor work. I was using the gym mats, but my knees, lower back, and glutes were hurting from being on the floor. This mat is the perfect thickness and feels wonderful during floor exercises. It gives me the extra cushion I need without being difficult to use. It’s also lightweight, durable, easy to clean, and easy to roll up for transport. The pink makes me smile. That said , the mat makes the classes more enjoyable.

Great value

Color: Aqua, Style: 1-Inch

Perfect exercise mat. It is nice and thick, and comfortable to kneel and lay on. Can't comment on durability, but so far, so good. Recommended.

PLUSH! Fabulous yoga mat!

Color: Black, Style: 1/2 Inch

SO comfortable! It feels like a soft memory foam padding. I use it for several exercise classes and it is great for all of my needs! I love the strap it comes with to keep it rolled up in between classes and the ability to carry it anywhere.

worth it for the price

Color: Pink, Style: 1/2 Inch, Color: Pink, Style: 1/2 Inch

i got the pink and it’s a super cute color in person! came with the strap which was nice too. thick and comfy - not sure how durable it is, as i just recently purchased it. only thing was the smell after taking it out of the box. very chemically scent but only lasted about a day. overall i love it and hope it holds up!
