I have a Brand New king size mattress from Serta, this particular mattress is one of the best in the market, with many different layer of memory foam, including cooling gel.
Extremely comfortable, I have the same model in my guest room, always get complements about the comfort level. (medium soft)
This particular mattress was only used in 2 different model homes for staging only, so it always stay in the original plastic.
No issues with it.
Manufacture Date: 2015
