This memory Pocket mattress features a super soft cool touch flame quilted top panel which is luxuriously comfortable and also helps to promote a cool sleeping surface. The mattress contains a Bonnell traditional spring open coil 1000 unit which distributes the weight and pressure over a large area. It has a layer of revolutionary airstream memory fibre. Airstream memory fibre is designed to mimic the effects of memory foam without the associated heat discomfort that some sleepers experience with memory fibre foam.
