Rebuilt and refurbish is not the same. Refurbish could be just cleaning outside, but rebuilt is rebuilding the mattress completely.
After manufacture takes a used mattress back, manufacture removes the cover and make sure all the spring are in good order. Manufacture sanitize it and the manufacture puts on brand new cover on it.
On outside of mattress, you will find two labels, one stating who sanitize it. All mattresses are manufacture here California, which does meet the strict law here in California.
