I bought S7 california king 6 feet. But product ship to my house was  5.5x6.5 feet 10 inches thickness. However the QC paper attached on the bed is 6x6.5 x 12 inches which is different from BedGear standard (as mentioned in Bead Gear web page). I did complaint to BedGear  Thailand and got unfortunate answer from the company that it was the correct size
