Count is only one field
Compare count or spring density with gauge, height, diameter/layout and the finished mattress construction.
Pocket spring performance depends on the full spring specification. Count is useful, but buyers also need gauge, height, zoning, edge support and the surrounding comfort layers.
Pocket spring specifications are often reduced to one headline number, but count alone cannot describe the support unit. Buyers should compare spring count or density together with coil diameter, spring height, wire gauge or diameter, zone layout, edge support and the finished mattress construction.
This guide connects those fields to a practical OEM brief so a pocket spring mattress can be compared across suppliers without relying on marketing claims such as high coil count by itself.
Compare count or spring density with gauge, height, diameter/layout and the finished mattress construction.
Wire gauge should be selected with target firmness, spring geometry and comfort layers.
Zone count should support a defined product story or comfort objective rather than being added as a decorative specification.
Perimeter design should be specified alongside the spring unit and tested in the finished mattress.
| Specification field | What it tells the buyer | What to confirm | Common mistake |
|---|---|---|---|
| Spring count / density | How many individual spring units are used in the defined size or area | Reference size, count method and spring layout | Comparing counts from different size bases as if they were identical |
| Wire gauge | One input into spring stiffness and response | Gauge plus spring geometry and target firmness | Treating gauge as the only firmness control |
| Spring height | Support-core depth and available travel | Height with total mattress construction | Changing spring height without rechecking the layer stack |
| Zoning | How support varies by body area | Zone count and actual layout | Using a zone number without defining what changes |
| Edge support | Perimeter reinforcement strategy | Method, materials and sample behavior | Leaving edge performance outside the spring specification |
A spring count is only meaningful when the reference mattress size and spring geometry are known. Smaller-diameter coils can increase the count within the same area, so count should not be treated as a standalone quality score.
When suppliers quote different reference sizes or use density per square meter, normalize the figures before comparing. Keep count tied to the actual support-unit dimensions used in the approved mattress.
Wire gauge or diameter influences spring stiffness together with coil diameter, height and number of turns. Zoning changes selected regions of the support unit through wire, geometry or layout differences.
Define the zone count, zone location and intended product benefit rather than simply asking for more zones. Edge support should also be described as a construction—reinforced coils, foam encasement or another approved design—not as a generic feature label.
Request the same reference mattress size, spring height, count/density method, wire specification, zone layout, edge design and pocket-fabric requirements from each supplier. Then compare those values with the target firmness and comfort stack.
A lower-count unit can still be the correct choice for a value model, while a higher-density zoned unit may fit a premium hybrid or hospitality program. The specification should follow the product position.
The spring unit should be approved together with the comfort layers, edge support, cover construction and total mattress height. A change in spring count, wire gauge, spring height or zoning can alter the finished feel even when the exterior design remains unchanged.
For repeat orders, record the reference mattress size, count or density method, wire specification, spring height, zone layout, edge-support construction and pocket-fabric requirement in the approved specification. Use the finished sample as the final reference for the complete build.
When you need exact reference values, open the Technical Database for detailed spring, foam, fabric and finished-mattress records that support quotation and specification work.
No. Compare count or density together with coil diameter, height, wire specification, zones, edge design and the finished mattress construction.
Zoning means selected regions of the support unit are intentionally designed differently. The specification should state how many zones are used and how those zones are created.
No. A higher count can result from smaller coils and must be evaluated with wire, height, geometry, comfort layers and product positioning.
Because the same count means something different in different mattress sizes. The comparison needs a defined area or density basis.
Name the actual construction—such as reinforced perimeter coils or foam encasement—and include it in the approved support-unit and finished-mattress specification.
Send the size range, quantity, target construction, firmness, materials, packaging, destination and documentation requirements so the project can move into quotation and sample review.
