These rugs are amazing for my back.  I LOVE to cook, but standing takes its toll on my lower back and especially knees.  Often spend time peeling, cutting, preparing meals at or near the sink.  FINALLY, I am comfortable.  Could stand for hours on the mats.  Only regret is not purchasing them earlier.  Might add, the designed mats fit so much better with the homes theme than the plain brown.  Best money I’ve spent in years, should have pulled the trigger sooner!
