# How do I calculate the carbon footprint of a pocket spring mattress?

Canonical: https://senseible.earth/answers/pocket-spring-mattress-carbon-footprint

Weigh the steel springs, foam layers, fabric and non-woven per mattress and multiply by supplier figures. Add spring coiling, pocketing, quilting and assembly energy, then divide the plant's energy by mattresses made.

## Material

- Steel spring wire.
- Polyurethane or latex foam layers.
- Ticking fabric, non-woven pocket fabric and adhesive.

## Process

- Coiling springs and sealing them in non-woven pockets.
- Quilting the cover.
- Assembly, roll-packing or flat packing.

## Per mattress

Report per mattress by size and weight. Foam and steel usually make up most of the footprint.

## Worked example: plant energy per mattress (one month)

- Electricity: 60,000 kWh x 0.710 = 42,600 kg CO2
- Mattresses made: 6,000
- Plant total: 42,600 / 6,000 = 7.100 kg CO2 per mattress
- Add spring wire, foam and fabric for the full figure

Inputs are illustrative; use your own bills and production records.

## What Senseible does here

Senseible reads the plant's electricity bills (CEA grid factor 0.710 kg CO2 per kWh, CO2 Baseline Database version 21.0) and fuel invoices (IPCC 2006 defaults) into a fingerprinted Scope 1 and 2 record, the plant-level input to a per-unit figure. Bought-in materials go to the supplier evidence trail; product reports are self-declared drafts.
