Honestly this mattress for me is completely bad, (1) pillow top dosent have the material been described, (2) the mattress is more medium to soft.. not firm.. (3) the edges are more than soft and the coils popped out there is no protection around the mattress, just a tiny fabric...(4) I completely sink into the mattress when I laying down and already has a curve, my back problem gets worse, I have used only for less than a month, definitely need to returned, is the second mattress I bought on wayfair,  dont waist your money and time, look for a real mattress store..
