My husband was reluctant to go to a mixed mattress ( spring  memory foam) I finally talked him into it and im glad I did HOWEVER this mattress is NOT FIRM! We had a California King several years ago that was a plush pillow top, its not THAT squishy BUT if youre wanting firm firm this is not the mattress for you my husband has come to grips with it but if I had it all to do over again id have gotten this mattress but in EXTRA FIRM!!
