Silentnight Geltex Affinity 1350 Mattress

The Geltex Affinity 1350 features the 1350 zoned Mirapocket spring system with an 6cm Geltex comfort layer.

The mattress offers a unique combination of unparalleled breathability to prevent the body from overheating, perfect pressure relief preventing pressure points from building and optimal body support providing perfect spinal alignment and support throughout the night. The Geltex Affinity 1350 offers the ultimate sleep solution.

The Affinity features Silentnight’s exclusive Miracoil® spring system as well, which contains 1350 individual springs housed in separate fabric pockets. The advantage of a Miracoil® mattress is each spring responds independently to your body, producing exceptional zonal support that tailors itself to meet your specific needs.

The mattress is ideal for use on bedsteads and divans.

Purotex cover, treated to reduce moisture and dust-mite allergens to create a drier, fresher and all-round healthier mattress. This mattress is hypoallergenic and dust mite resistant for a healthier sleep.
