I loved the spinal labs back stretcher foam
I loved the spinal labs back stretcher foam.  It feels amazing and really worked to alleviate my back pain.  This foam roller is from the same Spinal labs but the foam is definitely not squishy.  In fact, it is very hard to the touch and does not compress (probably by design).  In comparisons with a cheap foam roller that I have, this one from Spinal labs should last a long time and I do not think it will lose its shape over time.  In terms of comfort, this roller works especially for rolling out the gluts and hamstring.  On my back, it hurts a little more - maybe a little more comfortable than my wooden back roller but definitely not like the soft foams ones.
