I am a designer, and spend about 6-8 hours on my feet every day, with my back haunched over the drafting table. This routine results in the worst back pains at the end of each day, that causes araw numbness near the tip of my spine. The foam roller relieves some of that by applying pressure to specific spots on my back.
My wife places one of this rollers in the back of her car seat for the friends to use during the ride. The foam roller has warped slightly because of the position that itisusedon. To maintain the structure and form of this roller, it is best to place it on an even surface during use.
