• WINNER! The Sealy Nostromo has won the Which? Magazine award for the 'Best in Test' mattress! The Nostromo scored a whopping 77% score, beating the other 28 mattresses easily. Which? Magazine also declared the Sealy mattress the "best mattress we've tested in years." Praise indeed.The Sealy Nostromo is the wonderful pillow top mattress from the Posturepaedic Sealy Collection. This mattress is built with the latest materials, technical advances and know-how from this World famous bed brand. The Nostromo has a well-deserved place right at the top of the new Posturepaedic Pocket Collection. This incredible new bed offers a Medium to Soft feel, great support and luxurious comfort.

The Sealy Nostromo mattress features the 1400 Pocket Spring system, which has featured in many of the bestselling Sealy mattresses of late. This Pocket Spring unit is designed to offer luxuriously soft comfort, but also to provide excellent support, exactly where required and instantly. The Sealy Pocket Springs move individually to provide very precise support. Each spring moves up and down to support the body's contours and movements perfectly. The springs work independently, not sharing the weight energy with one another, which results in very precise support.

The Nostromo mattress has a deep, soft layer of Latex on the surface. This layer of natural Latex (known as Innergetic Latex by Sealy) acts to instantly mould to the contours of the body, effortlessly supporting the spine and further enhancing the luxurious feel of the bed. Latex requires no heat to soften, and is actually a great material for maintaining a cool and dry sleeping environment. Furthermore, this material is ideal for those with allergies, as bed bugs and mites cannot thrive on latex.

The surface material of this Sealy mattress is a quilted, soft, stretch knit fabric that is as tactile as it is luxurious. This cover fabric is made from Tencel, a naturally occurring fibre that Sealy have been applying to their mattresses for 2 years now with wonderful results. This fabric works to maintain a comfortable heat and moisture level at all times, and maintains a 'micro-climate' within the bed, by absorbing excess heat and moisture when required, and releasing it when the external climate allows. Sealy has also infused the fabric with Purotex. This treatment has Allergy UK's seal of approval as it features slow release, friendly bacteria. This process reduces odour within the bed and also controls other allergens.

This Sealy mattress is a no-turn mattress, and requires rotating once per Season, more often in the first few weeks after delivery.
