CORE TECHNOLOGY

Medical Grade™ foam and PostureCell® technology

At the core of every Mammoth mattress is Medical Grade™ PostureCell® foam — a material developed for healthcare environments, where pressure and heat are managed as a matter of clinical routine.

What is Medical Grade™ foam?

Medical Grade™ foam is the pressure-relieving foam at the core of every Mammoth mattress. It responds to body weight rather than resisting it, so weight is distributed across a larger contact area, and its cell structure allows heat and moisture to move away from the body.

How is it different from conventional mattress foam?

Conventional comfort foams are generally designed for surface softness. Medical Grade™ foam is designed around how load is carried and how heat moves, which is why it originated in healthcare environments rather than in mattress retail.

INSIDE THE FOAM​

PostureCell® technology

Cells that respond on their own

PostureCells® are independently responsive cells built into Mammoth Medical Grade™ foam.

Each cell carries load individually and returns as load is removed. The result is a surface that follows the shape of a body rather than its outline, and channels between the cells that give heat and moisture a route away from the skin.

Mammoth foam is itself zoned, with firmer side support and additional support through the lumbar area. That foam zoning sits above, and is separate from, the pocket spring zoning underneath it.

Weight distribution​

Load spreads across the surface

Cells cushion independently, so weight is carried by many points instead of a few.

Airflow and heat​​

Channels move heat and moisture​

The spaces between cells give heat and moisture somewhere to go, rather than holding them at the skin.

Independent response​

Movement responds independently

Because cells respond individually, movement on one side of the bed may transfer less across the surface.

What PostureCell® does

Four documented effects

Pressure, temperature, movement and support. Every part of Mammoth technology is aimed at one of them.

Weight Distribution

Cells cushion independently, so weight is carried by more of the surface.

Body Contouring

The surface responds to different body shapes rather than a single average profile.

Partner Disturbance

Independent response may reduce how far movement travels across the surface.

Airflow

Channels between the cells support airflow through the comfort layer.

What is PostureCell® Technology?

PostureCells® are independently responsive cells built into Mammoth Medical Grade™ foam. Each cell carries load on its own, which allows the surface to distribute weight, contour to different body shapes, and move heat and moisture through the channels between cells.

No. Memory foam responds to body heat and softens as it warms. Medical Grade™ foam responds to weight, and its cell structure is designed to allow airflow rather than to trap heat.

 

Mammoth technology is supplied to authorised Australian retailers, who sell mattresses using it under their own product names. Ask for Mammoth technology in store, and the retailer will show you which of their mattresses uses it.
