How Spring Count Is Marketed (Factory View)
Published 2026-08-04. Last updated 2026-08-28. Desk research by Kaiser Khan — we have not product-tested spring count marketing. This is not a shop review and not medical advice.
In short
Spring count headlines are easy to inflate. Always ask which UK size the count refers to, whether microcoils in the comfort layer are included, and whether the figure is for one unit or stacked units. Higher counts can mean finer pocketing — not firmer support or longer life by themselves. Read count with gauge, tension and fill mass.
- Headline spring count
- Not a score
- First question
- Ask the size
It is a packing number for a named size, not a quality mark.
Double, King or Super King? The same density changes the count.

What materials go into this mattress?
Typical builds use pocket spring units, microcoil comfort layers, open coil units. Exact stacks vary by model. Read the spec, not the shop slogan.

- microcoil comfort layers
- open coil units
How long does this mattress typically last?
A typical range is 7– 10 years. Body weight, base support and rotation change that. It is not a warranty promise.

What is the honest way to read a spring count?
Same packing density gives different counts on different sizes. One thousand springs in a UK Single (90 × 190 cm) is a denser pack than one thousand in a UK Super King (180 × 200 cm). Always ask which size the number is for. Ask for springs per square metre when you compare sizes. Basics: spring count explained.
A headline count is not a quality score. It is a packing number. Wire gauge, tension and fill mass still decide how the bed sleeps and how long the core lasts.
How do shops inflate the number?
| Pattern | What to ask |
|---|---|
| Count with no size | “Is that in Double, King or Super King?” |
| Giant number on a soft bed | “Is tension soft while count is high?” |
| Microcoils in the quilt | “Does the headline include comfort-layer microcoils?” |
| Dual / triple units | “What is the count in the main support unit alone?” |
| Open coil vs pocket | Different spring sizes — do not compare raw counts across families |
None of these patterns is automatically a lie. Microcoils can be a real comfort layer. Dual units can be a real build. The defect is adding them into one giant number and letting you think it is one support unit in your size.
Are microcoils a scam?
No. Small comfort-layer coils can improve surface contour. They are still not the same as a denser main pocket unit. A clear ticket separates:
- Main support unit count, with UK size.
- Optional microcoil layer count.
- Tension and gauge notes.
See wire gauge and coil types. If the seller cannot split the number, treat the headline as marketing until they can.
What should I ask instead of “how many springs?”
Ask for count in this UK size. Ask whether microcoils are included. Ask spring tension for your weight — tension vs feel. Ask comfort GSM or fill weight. Ask how the edge is finished. That list tells you more than a single five-digit boast.
See how to read a mattress spec and questions to ask in a bed shop.
Does a higher count last longer?
Not by itself. Finer coils packed tightly can contour well. Thin wire can also fatigue sooner if the gauge and temper are poor. A lower count with better materials can outlast a high count with thin padding. Factories watch gauge, barrel shape, unit height, edge finish and fill mass. Shoppers are taught to watch the biggest number. Invert that habit.
Open-coil counts are a different family. Do not crown a pocket bed because its count is higher than a Bonnell unit. Compare pocket sprung with open coil on mechanism first.
Why does the same density change the headline?
Area changes. A UK Single is 90 × 190 cm. That is 1.71 square metres. A UK Super King is 180 × 200 cm. That is 3.60 square metres. If both mattresses use the same springs per square metre, the Super King headline is more than twice the Single headline. The beds are not “twice as good”. They are a larger floor.
| UK size | Plan (cm) | Area (m²) | What a raw count does |
|---|---|---|---|
| Single | 90 × 190 | 1.71 | Smallest headline for the same pack |
| Double | 135 × 190 | 2.57 | Mid headline |
| King | 150 × 200 | 3.00 | Larger than Double |
| Super King | 180 × 200 | 3.60 | Largest headline for the same pack |
We do not publish a “good” springs-per-square-metre score. Makers use different wire and different barrel shapes. The table is only here to show why size must sit on the ticket.
In short: ask for springs per square metre, or insist on the count in your size.
You do not need a factory calculator. You need the seller to name the size on the ticket. If they will not, treat the boast as a poster, not a spec. See spring count explained.
What else gets bundled into a giant number?
Comfort-layer microcoils. A second spring unit under a pillow top. Edge coils that are a different family. None of those is automatically dishonest. The defect is one giant number with no split. A clear ticket lists the main support unit, then any extra layer, then tension.
Open coil and pocket sprung still should not share a league table. The coils are different sizes and they are joined in different ways. Compare mechanism first.
Who should skip a “highest count wins” table?
Skip it if you want this page to pick a winner. We will not. Skip it if you already have the count in your size, the tension band, and the fill mass — you already have the useful facts. A five-digit poster does not beat those three.

Frequently asked questions
How do brands inflate spring counts?
Common methods include quoting a count without the mattress size, adding microcoils from a comfort layer into the headline number, or summing two spring units. Always ask for the main support unit count in your UK size.
Is a higher spring count always better?
No. Count mainly tracks packing density for a given size. Wire gauge, tension, comfort fillings and edge finish decide feel and durability more than a single headline number.
What should I ask instead of “how many springs?”
Ask for spring count in this UK size, whether microcoils are included, spring tension for your weight, and comfort GSM or fill weight. See how to read a mattress spec.
Can I compare open-coil count with pocket count?
Not as a like-for-like score. Open-coil units use larger, linked springs. Pocket units use smaller, independent coils. Raw counts across families mislead. Compare mechanism first, then density within one family.
How should I compare spring count on a Single and a Super King?
Ask for springs per square metre, or ask for the count in your UK size. The same packing density gives a smaller headline on a Single (90 × 190 cm) than on a Super King (180 × 200 cm). A raw number without size is not a score.
