Coconut Coir Support Core

Purelay coconut coir support core
Support core

Firmness that comes from structure, not density.

The support core decides whether a mattress still feels the same in year eight. Coir is a natural fibre with genuine structural stiffness, so it resists the gradual compression that produces permanent body impressions in foam cores.

Key takeaways

  • Firm, airy structure for long-term stability.
  • Resists the gradual compression that causes permanent body impressions.
  • Ethically harvested from a renewable source - a by-product of the coconut harvest.

What a support core is for

The comfort layers decide how a mattress feels in the first minute. The support core decides how it feels in year eight.

Coir holds its shape because its stiffness is structural rather than a function of density, which is what separates a core that lasts from one that slowly develops a hollow where you sleep.

Airflow through the core

Coir is a loose fibre structure, so air moves through the middle of the mattress rather than stopping at the comfort layers.

That matters for moisture as much as temperature: a core that breathes does not hold humidity in the centre of the mattress where it cannot escape.
