Coil count is the total number of springs across a mattress unit, quoted for a standard double size. As the count rises, individual coils get thinner and sit closer together, so the unit follows body contours in smaller steps. A higher count is not automatically better: it means something only alongside wire gauge and coil height.

What does the number count, and over what area?
Coil count is the total number of springs in a pocket spring unit. Each spring sits in its own fabric pocket, the pockets are arranged in rows and columns, and the count is simply the total of that grid. The trade quotes the figure for a standard double mattress surface.
The only way to fit more coils into the same area is to make each one narrower. As coil diameter drops the wire has to get thinner too, otherwise the tighter winding cannot compress as far as it needs to. A rising count therefore does not just mean more springs — it means the whole geometry of the unit has changed.
What that buys in practice is resolution. More and narrower coils let the surface answer a shoulder and a hip separately instead of treating them as one region. That is exactly what following body contours in smaller steps amounts to.
Count, wire gauge and coil height work together
Three numbers describe a pocket spring unit: how many coils there are, how thick the wire is, and how tall each coil stands. Knowing one of them does not describe the unit.
Wire gauge is the main lever on firmness. Thicker wire resists compression harder; thinner wire gives more easily. That is why a high-count unit wound from thin wire can end up softer overall than a lower-count unit wound from thicker wire — the count on its own says nothing about how firm the result will be.
Coil height sets the working travel. A taller coil sinks further before it stiffens; a shorter coil reaches its limit earlier. Height is decided per order, because it has to suit the mattress build the unit goes into.
Read together, the three make the count meaningful. Quoted alone, the count is the value of one variable out of three, not a summary of all of them.
Why does a count figure not travel between sizes or suppliers?
Because the figure is quoted for a standard double, putting two counts from two different mattress sizes side by side compares nothing. A larger surface holds more coils even when coil diameter and spacing have not changed at all: the number goes up while the character of the unit stays exactly the same.
The same problem appears between suppliers. Not everyone quotes the count on the same size, and not everyone counts the unit the same way. A count given without the size it refers to is not comparable data — it is a number without its context.
This also explains why the count is so often the only figure quoted: it is the easiest variable to raise. Narrow the coil, thin the wire, and the count climbs without the unit's support character improving at all. Marketing that leads with the count alone is leading with the number that is cheapest to inflate.
What should you specify when ordering?
Five items make a quotation comparable: the finished unit size, the coil count, the wire gauge, the coil height and the packing. Two quotations that state all five can be read side by side; one that leaves any of them out cannot.
Packing is as concrete a line item as the unit itself, because it sets the volume and therefore the freight. A pocket spring unit can be packed on a roll or on pallets; roll-packing is possible and brings the shipping volume of the unit down.
YAYLA's confirmed range in pocket spring production is 500 to 1200 coils, with height set per order. No value in that range is inherently the best one: the right count falls out of the mattress you intend to build — its size, the firmness you are targeting, and the comfort layers that will sit above the unit.
| Variable | What raising it does | What it trades away |
|---|---|---|
| Coil count | More and narrower coils fit the same area; the surface answers smaller regions separately | Each coil carries less load on its own, and the count says nothing about firmness by itself |
| Wire gauge | Thicker wire; each coil resists compression harder and the unit feels firmer | Less give under light load, and more steel and more weight per unit |
| Coil height | More working travel before the coil reaches its limit; a deeper, more gradual sink | A thicker finished unit, which then has to fit the mattress build |
| Unit size | A wider surface holds more coils at the same spacing | The figure rises with no change to the coil itself, so it cannot be compared across sizes |
Frequently Asked Questions
- Is a higher coil count always better?
- No. A higher count only tells you there are more and narrower coils in the same area; whether the mattress is better depends on wire gauge and coil height as well. A high count wound from thin wire can feel softer overall than a lower count wound from thicker wire.
- What mattress size is a coil count quoted for?
- For a standard double. Because a larger surface holds more coils at the same spacing, two counts from different sizes cannot be compared unless both are stated on the same size.
- Does raising the coil count make a mattress firmer?
- Not on its own. Firmness comes mainly from wire gauge and coil height, and raising the count spreads the same load over more and thinner coils, which can make the surface feel softer rather than firmer.
- Why do two suppliers quote different counts for the same mattress?
- Because the figure depends on coil diameter, spacing and the size it is quoted on, and not every supplier states which. Ask for the size, the wire gauge and the coil height alongside the count, and the two quotations become comparable.
- Which coil count should I choose?
- The count follows the mattress being built — its size, the firmness targeted and the comfort layers that will sit above the unit — rather than being picked on its own. YAYLA's confirmed range in pocket spring production is 500 to 1200 coils with height set per order; see the product page or ask us for the combination that suits your build.
