I love the mat. It's thick and very comfortable on my knees. However, when I opened it for the first time at my yoga class, there were several cuts or punctures in the foam. I attempted to return it and the seller offered me a 10% refund due to the damage. I am concerned that the mat may deteriorate due to the damage it came with, but I need it and have no idea if the cuts will matter over time. So I accepted the $3 refund and am keeping the mat.

Best mat purchase yet

I love this mat. I wish they had it in larger sizes. The only one I have truly non slip. Extremely comfortable especially on my back. Great price.

Great workout mat

Color: Green

It’s very thick and soft so it makes exercising a lot easier. It rolls easily ready to store. And it seems very durable. It is also flexible for certain exercises for balance.

Very sturdy. Great Quality

Color: Navy Blue

This is a very dense, thick mat. It's great if you have bad knees or just need/want a thicker mat. The carrying strap with velcro closures is easy to use.

Great cushioning, easy storage

Color: Blue

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.
