I am so happy I bought this. I do back stretches, and need to be on the floor.. Getting up & down is hard at 77, and carpets are hard. This helps sooo much! I don’t hurt my knees when getting down or getting up. The mat is comfortable and provides plenty of padding. It is easy to roll up and store with the included strap. I am tall, and there is extra length, so my head and feet are on the mat. This was a good purchase! This has not torn, and wipes down easily. It doesn’t attract dog hair, which is another reason I wanted a mat.

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.
