+Good Squish! Excellent for gentle floor exercise!  Very Pleased!
I've just spent 3 months in physical therapy learning techniques to help my neck and lower back (disc degeneration all over the place, bone spurs, arthritis, etc) and am determined to not get to such a bad state again.  I use this as my base for my stretches and exercises.  It has just enough squish to not feel like I'm dying but it is supportive.  Since it's only about 4 inches in height it provides enough to balance but no injury.  At only 36 inches that's long enough mostly cover the length of my spine.  It's nubby so it doesn't slide on the floor and it won't suction to my skin.  I'm VERY happy with the purchase.  I bought a full roll at R*EI for much more money for much less quality just last week...I so wish I would have waited and shopped here first!
