# Spring Tension vs Comfort Feel

> Spring tension is how hard the spring unit pushes back. Wire thickness and coil shape set it. It should match your body weight. Comfort feel is how soft the padding and foam on top feels. Firm springs can sit under a soft quilt. Mixing up these two specs causes many early buyer regrets.

## Key facts

- Materials: steel pocket springs, wire of varying gauges, wool cotton foam comfort layers
- Typical lifespan: 7–10 years

## Two different specs

| Spec | What it is | Set by | Choose mainly by |
| --- | --- | --- | --- |
| Spring tension | How hard the spring unit pushes back | Wire [gauge](/mattresses/wire-gauge-and-coil-types), coil shape | Body weight |
| Comfort feel | How soft the sleep surface feels | Wool, foam, latex, quilt depth | Sleep position and what you like |

## Why weight comes first for pocket sprung beds

- **Too soft a unit for a heavy sleeper** → you sink through the top. It feels "saggy" even when new.  
- **Too firm a unit for a light sleeper** → you sleep on top. Shoulders and hips can ache.  

Then set top plushness with fillings — see [natural fillings](/mattresses/natural-fillings-wool-cotton-horsehair) and [pillow-tops](/mattresses/pillow-top-and-surface-types).

## Tension bands (education only, not brand rules)

Each maker publishes its own charts. In UK pocket sprung education, **thicker wire / firmer tension** often links to higher body weight bands. **Medium tension** often suits mid-range adult weights. Always read the maker's weight guide for that model.

## Couples with different weights

One shared tension is always a compromise. Options: [zip-and-link dual tension](/mattresses/couples-and-zip-and-link), zoned units, or accepting a middle tension with top tuning.

## Frequently asked questions

### Does firm mean firm springs or a firm surface?

Shop labels mix both. Ask whether "firm" means spring tension and wire thickness, or the quilt and padding on top. On many pocket sprung and hybrid beds, these are separate specs you can pick independently.

### What spring tension do I need for my weight?

Heavier sleepers usually need higher tension (thicker wire, firmer unit) so they do not sink through the top layers. Lighter sleepers on an overly firm unit may feel pressure on top. Exact gauges vary by maker — use weight as the first filter, then sleep position for top feel.

### Can a soft topper fix the wrong spring tension?

A topper only changes top feel. If the spring unit is too soft for your weight, a topper will not fix alignment. If the unit is too firm, a soft topper can help pressure relief but will not change the spring gauge.
