I purchased this bed because it had received so many great reviews, but I can only agree with the one that said that the bed reminded them of a rock. It is very firm...too firm for me. When I wake up after sleeping on my side, my arm has gone to "sleep" also! It also really makes my back ache. I am going to try a topper for it and possibly a mattress pad to see if it will be more comfortable before resorting to buying another mattress set.
