Featuring Sealy's own PostureTech 660 spring system with the added benefit of 1400 mini pocket springs, this is a very unique mattress. Sealy work with leading orthopaedic specialists to provide cutting edge products ahead of the field. The extra mini, pressure-responsive pocket springs provide outstanding support, backing up the super-supportive and highly popular PostureTech 660 system. The cover of the mattress incorporates Tencel, an innovative, eco-friendly fibre that naturally regulates your sleeping temperature and manages moisture for a great night's sleep, whilst discouraging bacterial growth. Sealy's edge guard provides edge-to-edge support, massively extending the sleeping surface and minimising roll-off. Sealy smart fibres also help to provide a fresh and dry, hypoallergenic environment, endorsed by Allergy UK.
