Mat reduced knee/leg pain
Your review: I bought this mat for my husband. He is in his 50's and his work requires him to be on his feet, on concrete, 10 hours a day. After a couple of days use at work, he said that the strain on his knees and legs was greatly reduced and this directly relieved his lower back pain and hip pain!
Pros: relieves joint stress
Cons: none, except maybe a little heavy.
