Mlily Supreme 10000 Review
Ten thousand springs in a king, close to the ceiling of what is sold in Britain and comfortably past the point where the number describes anything useful.

Verdict
Ten thousand springs in a king, which is close to the ceiling of what is sold in Britain and comfortably past the point where the number describes anything useful. This is a plush mattress with exceptional motion isolation, and it is not ten times the mattress a Premier 1000 is.
Buy it if
You want a plush surface with the best motion isolation available and you have compared the comfort layers.
Avoid it if
You want support. At this count each spring is about as thin as a spring gets, and a heavier sleeper needs the opposite.

| Specification | Detail |
|---|---|
| Type | Pocket sprung, very high count |
| Springs | 10,000 in a king size |
| What that requires | Very small units in thin gauge wire |
| Genuine benefit | Contouring and motion isolation |
| Not a benefit | Individual spring strength, which falls as count rises |
The scores
Exceptional at one thing, and the headline number promises something it does not deliver.
You are paying for spring count well past the point where it changes the experience.
Very fine gradation, very low individual spring strength.
A dense spring layer moves air well.
Not specifically reinforced.
The highest on this site. At this density almost nothing transmits.
Varies by seller. Check before ordering.
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 in the model name is the spring count in a king size. A double has fewer and a single fewer still, because spring density stays roughly constant while the area shrinks.
In the Memory and Memory Gel collections there are no springs at all and the number is a tier marker. That is the one place buyers get caught out.
What 10,000 springs actually means
A king size mattress is 150 by 200 centimetres, which is three square metres. Ten thousand springs across that area means roughly 3,300 springs per square metre, or one spring every 1.7 centimetres in each direction.
Springs that small cannot be made from thick wire and still compress usefully under a human body. So a very high count necessarily means thin gauge, small diameter units.
What you gain: contouring at a resolution finer than the human body needs, and motion isolation that is genuinely class-leading, because a partner's movement is absorbed by a handful of tiny units and travels almost nowhere. The 10 out of 10 above is earned.
What you lose: individual spring strength. A spring supports according to its gauge and height, not how many neighbours it has. At this count, the support comes from the collective rather than from any spring, which is a different kind of support and it suits a different kind of sleeper.
Who this is actually for
One clear case: a couple where one person is disturbed by the other's movement, and where both want a plush rather than firm surface. On that specific problem, nothing else in Britain does better.
Who it is not for: heavier sleepers, who need fewer stronger springs rather than more thinner ones. And anyone buying because 10,000 sounds like the most mattress available, which is the most common reason people end up here.
If motion isolation is the whole problem, note that deep memory foam beats any sprung mattress at it, because there is no mechanical linkage between one part of the surface and another. Ergoflex does that for considerably less.
A correction worth making
Commonly repeated, and wrong
Very high spring counts are presented as the top of a quality ladder, and a king size mattress is three square metres, so ten thousand springs means roughly one every 1.7 centimetres in each direction. Units that small must be made from thin gauge wire to compress usefully. The result is contouring finer than the body needs and outstanding motion isolation, at the cost of individual spring strength, which is the opposite of what a heavier sleeper requires.
Should you buy it?
Yes for one specific case: a couple wanting a plush surface where one is disturbed by the other's movement. On that problem it is excellent.
Otherwise, the Premier 2000 is the better mattress for most people and costs far less. If motion isolation alone is the problem, deep foam beats any sprung mattress at it.
Questions people ask
Is 10,000 springs better than 2,000?
Not as support. A king is three square metres, so ten thousand springs means roughly one every 1.7 centimetres in each direction, and units that small must use thin gauge wire. You gain contouring and motion isolation; you lose individual spring strength.
Who should buy a very high spring count mattress?
A couple wanting a plush surface where one is disturbed by the other's movement. On that problem nothing in Britain does better. Not heavier sleepers, who need fewer stronger springs rather than more thinner ones.
