WellnessMats® Anti-Fatigue Floor Mat Copper 5 "Heavenly Bliss." Dawn 19 June 2014 This review is for an older version of this product My home sits on a concrete raft instead of floorboards, so the floor is very hard indeed on knees and hips. I have had bad arthritis for 40+ years and when I saw this mat I decided to give it a go as I was in a great deal of pain. The feeling was instant bliss and the relief in my joints has to be experienced to be believed. I even slept better as the pain was less severe due to time standing on these mats for my fixed station chores. Yes, they are Well Worth the Money if you have sore joints or muscles. In the pic it looks dull brown. It Is Not. The mat shines. So glad I bought 2. BLISS!
