I was suffering from back pain Lumber 3,4,5 and also from neck pain. I am required to travel extensively. I purchased Frido cushions four at a time for all my seating places and one for car seat. I must say it was a great relief from pains. Now I can seat for few hours contineously in office and can travel three four hours at a stretch without break. I have also purchased back supports and using it every where. I strongly recommend this to those having such issues.
