Our verdict
Millbrook's pricing makes this an easy call. The 4500 has twice the micro springs (3,500 against 1,750), a richer fill with cashgora, and costs less for a double than the Serenity Luxury 2750 at the time of writing. The 2750's only lead is 1cm of extra depth.
The 4500 is the one to buy. Choose the 2750 only if it is the cheaper of the two on the day, or if matching the height of an old 31cm mattress matters to you.
