I have been using the Serta Bellagio at Home Pillow Top mattress for a little over a week now. This is a wonderful mattress. It doesn't droop or sag or leave indentations in the mattress or pulls one person closer to the other one. My back is not sore anymore when I wake up. I am sleeping all night, soundly, and comfortably. The mattress is firm yet not too firm, and I am feel refreshed in the morning. I am looking forward to not having to flip it in 6 months, only turn it, as this is a no-flip mattress. There was no smell from the materials or plastic when it was delivered. The stitching seems to be typical of Serta's reputation in that it's even and not loose. The fabric color combination is so rich looking that it's a shame to put sheets on it. I am very happy with the quality of this mattress.
