Mattress Construction

Materials Overview

The New Koala Calm As Mattress has four layers:

  • 1cm Quilted Plush Cover
  • 7cm Flippable Kloudcell™ Comfort with COOLMAX® Technology
  • ZoneOut Transition Layer (3 zones)
  • NoPressure Adaptive Core with 3 targeted high-density precision cut support zones and StayPut Edge Support.

Comfort Info

No more tossing and turning, as Koala mattresses have a Zero-disturbance® layer meaning you'll sleep soundly no matter who you sleep next to. It's like sleeping in separate beds, without giving up the cuddles.
All Koala mattresses come with an anti-bacterial treatment to help keep dust-mites and other nasties away.

Support Info

StayPut Edge Support is effectively a firmer foam perimeter that creates super stable edges so that you can sit or lie right on the edge of the mattress without falling off.

Comfort Specs

The ultra cooling comfort layer made with COOLMAX® fibre is easy going on your skin, and helps your body feel cool and dry, even on muggy nights.
The ZoneOut Transition Layer is fitted with air tunnels meaning any excess or unwanted heat is efficiently dissipated which helps make for a cooler night's sleep.

Support Specs

The Calm As mattress has multi-layered zoning:

  • The ZoneOut Transition Layer has 3 high density targeted support zones to disperse your weight while providing extra support for your lower back.
  • The NoPressure Adaptive Core is designed to take the pressure off. This high-density reactive layer with 3 precision cut support zones offers a firmer support base right beneath the hips that prevents your body from sinking into the mattress. This comes in handy when it comes to helping you maintain a healthy sleeping posture.

Fabric Specs

The cover on the New Koala Calm As Mattress is made with COOLMAX® technology, this quilted cover is designed to help cool your body down with permanent moisture-wicking tech, making it easier to fall asleep faster. The top fabric is 63% Polyester, 37% Polyester (COOLMAX® Fibre).
The anti-slip base fabric is 100% Polyester with PVC dot which helps keep your mattress securely in place.
