Medium-Firm Support

This mattress has a medium to firm rating, and offers 11 targeted zones that support your hips, shoulders, back and more. The memory foam contours to your body's natural shape and provides orthopedic support from head to toe, relieving pressure points and ensuring you get the best night's sleep possible.

Cool & Breathable

Stay comfortable and cool with the ventilated and temperature regulating fabric of this mattress. The fibres support faster evaporation, absorbing 60% more moisture than cotton and preventing any humidity or discomfort in the warmer months. The high-density Bio Nature® block foam is designed to be breathable, which helps you stay cool - ideal for surviving a range of temperatures all year round.

Ecological & Hypoallergenic

This mattress is 100% ecological, made with high quality organic fabric based on beeswax emulsions. The breathability is provided by special high density Bio Nature® Air Comfort foam, made with air vents to allow proper ventilation. The hypo-allergenic treatment and 100% anti-allergen fibres keep your skin protected from harmful substances, and the anti-dust-mite and anti-bacterial properties will help you sleep soundly in the knowledge that you're doing the best you can for your body.
