The Bellatrix Mattress is ideal for people of all ages. The mattress is specially equipped with a duo-surface design which includes anti-mite antibacterial fabrics and unbelievably soft cotton fabric. At the bottom, it is covered with a knitted straw layer that retains its natural properties to repel moisture. This makes it suitable for hot and humid climates (optional to add “such as in Hong Kong”). The core of the Bellatrix Mattress is a massage spring system made from high carbon steel designed to be sturdy and rigid. This provides the perfect support for posture and relieves pressure point build-up.
