Current option offered under this mattress name. Current purchasable page explicitly markets a 7-inch Medium version. The help center still says 6 inches, proving an unresolved documentation/generation conflict rather than permission to collapse the records.

Why these options share one page: They are sold under the same marketed mattress name. Firmness, height, and size choices stay together here, and any documented construction differences are explained beside the relevant option. A different marketed mattress name always receives its own page.
