Both tested and scored by Alexander Bowman. Scores use the same criteria for every mattress.
Our verdict
Both are Millbrook's 'Luxury' Serenity mattresses, but they sit at opposite ends of it. The 6500 has 5,500 micro springs to the 2750's 1,750, adds cashgora, and is 3cm deeper at 34cm.
The 6500 is a genuinely plusher, finer-grained mattress, and the one to choose if you want the best Millbrook makes. If your budget is closer to the 2750's, look at the Serenity 4500 instead, which outspecs the 2750 for less.
