Combining pocket springs with a deep geltex layer, the Silentnight Sublime Geltex mattress has been manufactured with comfort in mind. 

Pocket Springs

The Sublime Geltex features 2000 Silentnight pocket springs, each spring works individually to respond to your body shape and weight as you sleep in order to provide support for your entire body. 


Ideal for side sleepers, the Sublime Geltex mattress is a medium soft tension. 


Nestled atop the 2000 pocket spring system is a deep geltex layer for that added layer of cloud like comfort. 

Used for its high elasticity, geltex moulds to your body shape as you sleep in order to provide pressure point relief.  

With natural cooling properties, the geltex layer helps keep your body cool in the summer and warm in those cold winter nights. 

Purotex Cover

In order to ensure a healthier night’s sleep, the Sublime features a Purotex cover which provides a barrier against allergens and dust mites ensuring your mattress keeps that fresh feel.
