From Connie -
Do you have the Cheshire III PS King Size Mattress set. We slept on this at Best Western and it was wonderful.
Based on your description of the mattress it sounds like it is a Serta Perfect Sleeper made for the Best Western Hotel.
We sell Serta’s Current hotel line. They are separated based on the Quality of the Hotel chain; 3 Star, 4 Star, and 5 Star – I believe Best Western would be a 3 Star.
