Firmness Info

The Koala Calm As mattress has a double-sided comfort layer that you access by unzipping the cover, and flip this layer over. You can choose between medium-firm support and firmer support. Koala recommend trying the medium-firm default side first.

The Calm As mattress is the firmest, the Koala in the middle, and the Soul Mate is not quite as firm. The same order applies when using the softer side.

Mattress Construction

Materials Overview

The Koala Calm As Mattress offers firmer support and has five foam layers:

  • 1cm Quilted Plush Cover with COOLMAX® Technology
