These might be the best mattresses that we have ever had in stock. We are currently working at a 5 Diamond resort in the Lake Tahoe area and we are liquidating 258 Queen Serta double pillow top mattress sets and 235 King Serta double pillow top mattress sets. These mattress have only been used for 4-6 years and they are still in great shape. Every mattress had an encasement on them, so they were very well taken care of.
