Aireloom, Kluft, Bloomingdales?

I know that Aireloom mattresses sold at Macys are lower quality than the ones sold by Aireloom or from independent mattress stores, but Kluft - their higher-end line - is sold primarily through Bloomingdales which also sell seemingly high-end Aireloom mattresses, but usually marked around 50% off list price.

Is the Bloomingdales Aireloom the same quality as Macys, the same as the Premier line, or somewhere in the middle? Is the Kluft mattress sold there the real Kluft quality or is that the same deal as the Macy's Airelooms, a good name slapped on a cheap mattress?
