Mammoth Infinity Mattress Collection

Advanced pressure relief. Precision support. Three premium comfort feels.

The Mammoth Infinity collection takes responsive comfort and targeted support to the next level, combining advanced materials with a sophisticated 9-zoned nested pocket spring system for highly tailored support across the body.

At the heart of every Infinity mattress is 3-zone PostureCell® Medical Grade™ foam, developed from technology used in UK healthcare environments. Rather than relying on body heat to soften, PostureCell® responds to body weight, allowing the comfort layer to contour more immediately while helping reduce pressure, support posture and encourage airflow through the mattress.

Beneath this, the 9-zoned nested pocket spring system is designed to provide more precise support across different areas of the body. Softer springs through the shoulders encourage pressure relief, while firmer support beneath the hips and lower back helps promote comfortable spinal alignment.

The Infinity collection also combines Fast Temp fabric, natural wool and premium quilting foam to create a comfortable sleep surface designed to help manage heat and moisture. Cooling airflow channels through the PostureCell® layer further encourage ventilation throughout the mattress.

A premium support foam layer adds stability and helps create the distinct Firm, Medium and Plush comfort options across the range, while PostureCell® Medical Grade™ edge support and 90mm Probox® perimeter support reinforce the mattress and help maximise the usable edge-to-edge sleeping surface.

Choose Your Infinity Comfort

Infinity 7 – Firm
The firmest option in the Infinity collection, the Infinity 7 combines a high-density firm premium support layer with responsive PostureCell® comfort and precision 9-zone support for sleepers who prefer a stronger, more supportive feel.

Infinity 8 – Medium
The balanced choice, the Infinity 8 uses a medium premium support layer to deliver an easy-to-enjoy combination of cushioning, responsiveness and underlying support.

Infinity 9 – Plush
The softest option in the collection, the Infinity 9 features a plush premium support layer for greater cushioning and surface conformity while retaining the targeted support of the 9-zoned spring system underneath.

From the firmer feel of the Infinity 7, through the balanced comfort of the Infinity 8, to the deeper cushioning of the Infinity 9, every model shares the same advanced Mammoth technology while allowing you to choose the comfort feel that suits you best.
