Diced Foam Layer

Pressure Relief
The Harriet Superior is a pressure redistributing mattress that is divided into zones. This adapts to the body to alleviate pressure and pain. A contouring 4” pillow top quilted with a combination of plush fibres, special castellated diced cut foam, natural cotton and wool provides an extra layer of comfort.

Zoned Pocket Springs
This mattress features 1,600 zoned pocket springs to evenly distribute weight. Having different zones in the mattress means you achieve targeted support, offering a more therapeutic sleep. The individual springs are housed in separate fabric pockets for total support, enhancing circulation and alleviating pressure points.

Foam Encapsulation 
The Harriet Superior mattress is foam encapsulated maximising the sleeping surface and offering true edge-to-edge comfort and support. An outer foam border improves durability, sagging, and prevents “roll-off”. The design also increases longevity and comfort, without compromising the integrity of the core. 

Diced Foam Layer
A premium, 70mm layer of castellated diced-cut foam located in the top section of the mattress offers excellent re-distribution of body pressure helping to alleviate aches and pain. This unique layer design also provides an added level of support including back and spine alignment.
