This mattress made me a bit nervous at first. When it says firm, they mean firm. But once I lay down on this bed, the support and comfort it offers is 2nd to NONE! I am amazed! My back pain has lessened and I wake up feeling more rested each day than with my previous mattress. I don't toss and turn and wake up all night anymore. I highly recommend this mattress for anyone with back issues like nerves pinched, sciatica or even just frequent muscle spasms and such. This will help you like it did me!
