No two mattress companies have the exact same definition of “firm,” and everyone’s experience of what’s comfortable is different. That’s why we have a special methodology for rating the firmness of mattresses when we test them, taking into account the company’s scale and how the bed feels on different body types.
This is also where the check constraint comes in handy: since we created a check constraint that matched the partition constraint of the original partition when we created the copy, we can perform the attach without needing to validate that constraint again, which could take a few seconds. Since we don't need to validate, the entire swap is pretty much instantaneous.
