Advanced comfort technology. Targeted support. Three distinct feels.
The Mammoth Ascend collection combines responsive comfort, targeted support and temperature-conscious materials to create a more balanced sleep surface.
At the heart of every Ascend mattress is 3-zone PostureCell® Medical Grade™ foam, developed from technologies used in healthcare environments. Unlike traditional memory foam that relies on body heat to soften, PostureCell® responds to body weight, allowing the mattress to contour more immediately while helping distribute pressure across the sleep surface.
A 7-zoned nested pocket spring system works underneath to provide targeted support across different areas of the body, with softer springs through the shoulders for pressure relief and firmer support beneath the hips and lower back to assist body alignment.
The comfort system is completed with Fast Temp fabric, natural wool, premium quilting foam and cooling airflow channels to help manage heat and moisture throughout the night.
Around the perimeter, PostureCell® edge support and 90mm Probox® support reinforce the mattress and help create a stable, usable edge-to-edge sleeping surface.
Choose Your Ascend Comfort
Ascend 4 – Firm
The firmest option in the collection, the Ascend 4 is designed for sleepers who prefer a stronger, more supportive feel while still benefiting from responsive PostureCell® pressure relief and targeted zoned support.
Ascend 5 – Medium
The balanced option, the Ascend 5 combines cushioning and support in a versatile medium feel that suits sleepers looking for comfort without feeling either excessively firm or overly plush.
Ascend 6 – Plush
The softest and most cushioning option, the Ascend 6 provides greater surface conformity and pressure relief while retaining the targeted support of the Ascend pocket spring system underneath.
From the firmer support of the Ascend 4, through the balanced comfort of the Ascend 5, to the deeper cushioning of the Ascend 6, each model shares the same advanced Mammoth technology while allowing you to choose the comfort feel that suits you best.
