Key features
If you're in pursuit of an uninterrupted sleep, a perfect night's rest can be just a mattress away. Offering two independent sleeping zones, this unique technology minimises motion transfer and partner disturbance.

The Silent Partner Cosmopolitan range features a 5-zone nested pocket spring system providing additional support where it is needed most.


Motion Deflection BarrierTM
Minimises the transfer of movement between the sleep surfaces enhancing individual sleep.

Nested Pocket Spring System
This allows for the coils to be off-set, eliminating wasted airspace between the springs, giving ultimate support and comfort.

Micro Coil Spring System
Enhances conformance whilst assisting in a quicker recovery of the pillowtop.

Foam Box Construction
Promotes a seamless transition from the mattress edge to the sleeping surface increasing the available sleeping area.

The Cosmopolitan range is endorsed by the Chiropractic and Osteopathic College of Australasia.
