Millbrook Serenity Luxury 6500 vs Millbrook Serenity Luxury 4750: which is better?

Both tested and scored by Alexander Bowman. Scores use the same criteria for every mattress.
Our verdict
The model numbers suggest the 4750 is the cheaper step down, but at the time of writing a 4750 double costs more than a 6500 double, even on sale. The 6500 also has 1,750 more micro springs and is 1cm deeper.
Buy the 6500. The 4750 is a very comfortable mattress, but it only makes sense if it is discounted below the 6500 when you shop, and a sale purchase cannot be returned under Laudsleep's policy.
