Temperature Regulating
Reduces Movement
Relieves Pressure
Good for allergy sufferers
Our Climate Collection is innovatively designed to regulate the mattress surface temperature while you sleep. Graphite-based materials made with patented phase-change crystals and infused with copper beads, store and release the heat produced by your body to regulate temperature. The combination of a pocket spring system and a layer of memory foam ensures pressure-relieving, balanced support.
About Comfort Support
The Copper 1200 models fit into our Comfort Support range. These are neither too soft or firm. They provide just the right balance of support, however you sleep.
Enhanced temperature regulation
The memory foam within this mattress is integrated with phase-change crystals that work constantly to absorb, store and then release body heat. It is additionally infused, and works in harmony with minute copper beads. Highly-conductive copper acts as a thermal pathway, and moves the heat away from the material surface to cool the sleeper, therefore triggering the phase-change reaction. This combination of materials accelerates the speed of the temperature-regulating process, and will maintain an optimal airflow and sleep-surface temperature throughout the night.
Pressure relief
Responsive memory foam allows you to sink into the mattress and relieves pressure points as it conforms to the shape of your body. Pocket springs maintain the structure of your mattress and move independently as you move throughout the night, distributing your weight evenly for direct and precise support.
Benefits of copper content
Not only highly conductive, copper is also a naturally antibacterial and antiviral element. As it helps to speed-up and maintain your sleep temperature, it also ensures your mattress stays fresh-feeling and hygienic throughout its lifetime.
Make the most of your mattress
After unwrapping your new mattress, leave it in a well-ventilated room for a few hours. Any smell from the fillings will dissipate after a few days. We recommend using a mattress protector, airing your mattress regularly and rotating it each month. An electric blanket can be used on Climate Collection models, but will make the surface temperature warmer than normal. If you’re placing this mattress on a slatted base, ensure the gaps are no more than 7.5cm apart.
Try before you buy
This is an important purchase and it’s worthwhile to try your choice of mattress in store to make sure it's right for you. Our store Partners will be able to tell you more about its benefits, and recommend options based on your needs. For more information, call 03452 661 805 and we can tell you where the range you’d like to view is on display.
