Comfort, Support and Durability

CoolKnit & Climate Control
Special cotton-knit fabric combines breathable, antibacterial properties with cool-to-the-touch technology to help create a cooler, fresher and more comfortable sleeping environment.

Allergen Protect™
The mattress fabric helps protect against common allergens, including dust mites, contributing to a cleaner, fresher and healthier sleeping surface.

Pressure-Relieving Firm Foams
StayTrue™ firm comfort foams provide a stable and supportive feel while helping distribute pressure more evenly across the sleeping surface.

Zone Support
High-density foam reinforces the centre third of the mattress, providing additional support through the lower-back area, helping reduce body impressions and allowing the muscles to relax and recover.

DuraFlex™ Edge Support
High-density foam border inserts support the edge of the spring system, providing a firmer seating edge and increasing the usable sleeping surface.

Exclusive & Improved Double Offset Pro Spring System
The Double Offset Pro Spring System uses a responsive hinging action to deliver correct back support while helping limit the tendency for sleeping partners to roll together. This interconnected support system was originally designed by doctors.
