Experience the advanced technology of our open-cell Single 4G Ultra Memory Foam Mattress. The 4G Ultra uses particles to permeate the surface of the foam which work to improve heat & moisture flow while you sleep. Cooling comfort can be felt in our fourth generation mattress, providing a breathable & fresh sleeping space so you can wake up feeling refreshed. The innovative design promotes airflow by a massive 95% so body heat & moisture can be removed from the foam & still provide you with superior support. The 4G Memory Foam responds quickly to your body temperature meaning the mattress can remain fully ventilated & responsive to weight & movement during the night. Our deep 5cm top layer of 4G Memory Foam used in our mattress ensures you get a great night’s sleep. Beneath is a secondary layer of memory foam for further support, complete with an engineered reflex foam base. The engineered reflex foam base is designed with air cells for pressure relief & moisture dispersal channels that allow the mattress to breathe freely for perfect comfort & support. The base also offers further support & durability & the reflex foam means the comfort you experience is built to last. The 4G Ultra Memory Foam Mattress is finished with a quilted Adaptive Purotex mattress cover which works to combat common night time allergies & bacteria that can flourish during the night. Purotex is an active probiotic which is woven into the fabric to absorb moisture & eliminate dust mites for a healthy & antibacterial sleeping surface.
