Onni London+ mattress on a plain ground

Where the money goes

What is in it

Thirty five centimetres, built in two halves, closed with a zip.

  • The coreTwenty centimetres of individually pocketed springs in seven zones, with 2.0mm wire under the hips and shoulders and 1.8mm elsewhere. It is the slowest part of the build and the reason it lasts.
  • The perimeterSeven centimetres of 35 density foam encasing the whole spring unit, so the edge holds when you sit on it.
  • The comfort layerTen centimetres, two densities, built as its own product because it has to be replaceable. Medium one face, medium firm the other.
  • The surfaceGel memory foam, comfort foam and wave-profile airflow foam under a 400 gram cool-knit cover.
  • Made to orderNothing is built before you buy it. No warehouse, no stock write-off, no clearance sale of last season’s tension.
The two halves of the mattress

Built to come apart

The part that softens renews.

A pocket sprung core lasts twenty five years. The five centimetres above it last seven or eight. Every mattress you have thrown away was thrown away because of the part that wears fastest, while the part doing the work was still sound.

Ours unzips. When the comfort layer softens you replace the layer and keep the core. It is why the mattress is built in two pieces rather than one, and why we guarantee the core for twenty five years.

Worth knowing

Three things people ask

You settle the feel after

Sleep on it for a month, then tell us how it should feel. We make a new comfort layer to that preference, with our compliments.

It is made after you order

Which takes weeks rather than days, and is the reason nothing sits in a warehouse waiting to be discounted.
