These pillows were bought as a means to provide support for neck & shoulders.  They are much too high!  Rather than having my head 'across' the pillow, it is on the edge, giving no support.  I couldn't possibly put them in their packing cases to return them; I struggled to get them out of these so saw it as impossible to put them back in.  My husband doesn't mind his, as he likes its firmness.  The bamboo covers are very nice and probably would add to comfort, if I could sleep on the pillow.
