Combining a PostureTech spring system with a deep geltex layer and luxury pillow top, the Sealy Alson mattress has been lovingly handcrafted with comfort in mind. 

PostureTech Spring System

Sealy have revamped their entire mattress range by using the new expertly engineered PostureTech spring system which provides more support than a standard open coil spring as it responds to your body movements as you sleep.  

Geltex Layer 

Nestled atop the PostureTech spring is a deep geltex layer, used for its high elasticity, this fibre contours to your body as you sleep in order to provide a soft cushioning to the pressure points throughout the body, helping to soothe those aches and pains. 

Enhanced Breathability 

In order to ensure a fresher night’s sleep, the Alston features a mesh border to allow for maximum airflow throughout the mattress as you sleep which in turn helps the mattress keep that fresh feel. 

Pillow Top 

Adding the perfect finishing touch to this already exquisite mattress is a sumptuously soft pillow top allowing you to sink into cloud-like comfort. 

Mattress Care 

As the Alston mattress is single sided it won’t require turning, however, we do highly recommend you regularly rotate the mattress, this is easily achieved with the handles stitched into the mattress border and allows for even settlement of fillings and prolong mattress life.

100% Recyclable 

Sealy are proud to promote the fact that the Alston mattress is 100% recyclable at the end of its life with no components going to landfill.


Sealy are so confident in the quality of their mattresses they provide a 5 year guarantee.
