Even my 4 & 6 year old nephews liked lying on the larger arch
Seemed expensive for pieces of wood.  But i have big problems with muscle tightness and knots in my upper back and neck. This really works and stretched out my chest as well.  I didn't see an option with the nubs (little circles that are built into these for pressure points I guess, so I bought this flat one).  Even my 4 & 6 year old nephews liked lying on the larger arch.  They liked the stretch.
