Verdict

7.0/ 10

Three thousand springs in the Deluxe collection, which sits exactly where the spring count question stops having a simple answer. Here is the decision tree I would use, because past 2,000 the right number depends entirely on what kind of sleeper you are.

Buy it if

You want a medium to plush feel with fine contouring and you are of average build.

Avoid it if

You are heavier or you want firm support. Fewer stronger springs beat more thinner ones for you.

Decoding the range

The number is the spring count, except in the foam ranges

In Mlily's Gel, Deluxe, Premier, Supreme and Haluna collections, the number is the spring count in a king size. In the Memory and Memory Gel collections there are no springs at all and the number is a tier marker.

How many springs do you actually need

The complete answer, which applies to any brand rather than just this one.

Spring count by sleeper, in a king size
You areAim forWhy
Under 11 stone, any position1,000 to 2,000You do not load the springs enough for grouping to matter
11 to 16 stone, firm preference1,500 to 2,500You barely compress the surface, so fine gradation does little
11 to 16 stone, soft or plush preference3,000 and upYou sink, so each region must respond independently
Over 16 stone1,500 to 2,500, firmYou need stronger springs, not more of them
Disturbed by a partner's movement4,000 and up, or deep foamMotion isolation is the one thing high counts genuinely excel at

The row that surprises people is the last-but-one. A heavier sleeper wants fewer, stronger springs, because a spring supports according to its gauge and height, not according to how many neighbours it has. Very high counts are achieved with thinner wire in smaller units.

Past 2,000, compare the comfort layer

Once a mattress is past about 2,000 springs, what determines how it feels is what sits above them.

So comparing the Deluxe 3000 against the Premier 3000 on spring count tells you nothing, because they share it. Compare the depth, the comfort layer material and the stated firmness, and buy on those.

If they match on all three, the difference is the cover and you should buy the cheaper one.

A correction worth making

Commonly repeated, and wrong

Spring count is treated as a single scale where higher is better for everyone, and the right number depends on body weight and firmness preference together. A heavier sleeper needs fewer, stronger springs, because a spring supports according to its gauge and height rather than how many neighbours it has, and very high counts are achieved by using thinner wire in smaller units. High counts suit plush surfaces and add little on firm ones.

Should you buy it?

Yes if you are of average build and want a medium to plush feel with fine contouring.

If you are heavier or want firm, the Premier 2000 Ortho is the better mattress for you and costs less.

Questions people ask

How many springs should a mattress have?

It depends on weight and firmness preference together. Under 11 stone, 1,000 to 2,000. Average build wanting firm, 1,500 to 2,500. Average build wanting plush, 3,000 and up. Over 16 stone, 1,500 to 2,500 firm, because you need stronger springs rather than more of them.

Do heavier people need more springs?

No, stronger ones. A spring supports according to its gauge and height, not how many neighbours it has, and very high counts are achieved with thinner wire in smaller units. That is the opposite of what a heavier body needs.
