Hi neighbors, I have a queen size Sealy Calais pillow top firm mattress with box spring, very nice and used for only three years, with metal frame. It is almost 15" and very plush and comfy. I was about to post this on Craig's list and decided to see if anyone in the neighborhood would like to buy it. I cannot remember what I purchased it for, but I checked current prices (the current model is called Crystal Creek) and the cheapest I found for a new one like this is $1,200 for the set plus the frame. I will sell this set for $450.00. We could provide some assistance with moving it as well. Judi Teeter
