This is a nice mat for floor exercises.
Color: Aqua, Style: 1-Inch
I had some lower back issues and went to physical therapy. I used this mat for my floor stretches and exercises at home along with my big rubber ball. It made the floor work so much more comfortable. Beware of the smell. When I unroll it I still smell that “memory foam” odor, which takes some getting used to. I aired it out as instructed, twice, and it persists. It’s a wonderful mat so the odor is not a deal breaker. I’d buy it again.

Love my mat!
Color: Pink, Style: 1/2 Inch
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.

Thick, soft, perfect for my service dog to lay on in restaurants, etc.
Color: Blue, Style: 1/2 Inch
I bought this for my service dog to lay on in restaurants, etc. It's super thick and soft. I cut it in half and I'm using the other half for my dog to lay on in the car. Excellent quality and I love the carry strap.
