Received my Kingsdown Prime Collection mattresses. 
Mattresses took 14 days from ordering until they were delivered, mattresses were in wrapped in plastic and in boxes, so were in perfect condition. Fabrics used are beautiful. Hod a light chemical odor when first opened, I let set over night before making beds the smell was gone.
Mattresses very plush and comfortable!
Wait a few days before I reviewed, after three nights sleep they are very comfortable.
I previously have memory foam mattresses (never again) 
I would strongly recommend.
