The Single 4G Pedic Deluxe Memory Foam Mattress is a deep 23cm orthopaedic mattress ideal for those who require additional support combined with high levels of comfort. The mattress is especially suitable for those with back conditions due to the medical grade supportive base & top layer of high density memory foam. The deeper base layer offers increased comfort & is ideal for those with a larger frame. The superior medical grade base with zoned air channels makes this the perfect orthopaedic mattress. Designed with a dual HD memory layer, the mid layer acts as a lumber support, with a softer top layer of our exclusive 4G HD memory foam providing optimum comfort & pressure relief. Our unique 4th Generation HD memory foam is infused with particles which work to create a heat regulated sleeping environment thanks to advanced heat dissipation technology. The unique structure of the 4G foam enhances airflow by 95% producing breathable & odourless foam with superb convective heat flow. The memory foam contours to your body shape & relaxes quickly in response to body heat providing a luxurious & comfortable sleeping environment. The 4G Pedic Deluxe Memory Foam Mattress is finished with a quilted Adaptive Purotex mattress cover which works to combat common night time allergies & regulates heat so you can stay cool & dry throughout the night. Purotex is an active probiotic which is woven into the fabric to absorb moisture & eliminate dust mites for a healthy, hypoallergenic sleeping surface.
