I am extremely pleased with this purchase. The firmness is as advertised, medium, exactly what I was hoping for. I replaced a traditional mattress and box spring set I had had for awhile. I am no longer waking in the middle of the night with something aching. Love it, soooo comfy!  
This is my second major purchase with Wayfair. The bed in this pic is called Alberton, in case anyone is interested. Actually, the area rug was also purchased through Wayfair.  Service has always been excellent and timely with my personal experience being they are always ahead of the scheduled delivery date.
