Bedding Question

We are shopping for a new mattress at home and really enjoyed the ones in the cabin on SS. Does anyone have any idea what they use?

UK1, I searched first and didn't find the answer anywhere. ;)

I can only tell you that it is 78" long and 66" wide. The clearance below is 11.5" while the bed height is 21", so it is less than 10" thick. It felt medium soft to us. That's all I have, hope it helps!
