Our verdict
On specification this is not close. The 4500 has 3,500 micro springs to the 2500's 1,500, adds cashgora to the wool, cotton and silk fill, and is 30cm deep against 29cm. At the time of writing it costs only about £75 more for a double.
Buy the 4500 unless the 2500 is on a meaningful discount when you shop. The extra micro springs make it the more cushioned and better-balanced mattress for almost every sleeper.
