Harrison Spinks Platinum 12500 Mattress - No Turn

The Harrison Spinks Platinum 12,500 Mattress is a premium, no-turn mattress within the Harrison Spinks Turn Free collection. Handcrafted in Yorkshire, this mattress features a total of 12,500 springs in a king size, utilizing the latest spring technology, including the Cortec™ Quad Revolution® Pocket Springs and layers of HD 2500 and HD 4000 High Density Micro Springs.

Part of the Harrison Turn Free collection, the Hawaii benefits from filling technology meaning the mattress only requires rotation rather than turning the mattress over. This is an advantage for those who in particular may not wish to flip the mattress over.

Using the very best natural fillings combined with the latest spring technology from Harrison beds the Hawaii contains recyclable quad Cortec springs with posturfil & High Density springs to provide a sumptuous feeling mattress. Boasting 12500 springs inside a king size - this mattress is suitable for use on a Harrison sprung divan base or a variety of bed bases & bed frames.

The Platinum has a number of Harrison's own patented spring technologies including their Cortec Quad Revolution spring - This system uses an ultra fine wire construction representing the very best award winning spring technology. The combination of HD 2500 give the perfect balance of support and comfort - by using these HD springs the users body is intricately supported due to the surface area contact from each spring. 

The Micro HD springs are high density springs offer twice as many springs per layer as posturfil with 2500 springs per layer, for increased air circulation they feature perforated pockets that act as mini pumps to circulate the air in your mattress as you sleep ensuring fantastic ventilation.
