What will we do with your old bed/mattress?
We will do one of three things:
- A local charity may want it. We have given them many items in the last year
- We may recycle the mattress
- Some mattresses cannot be recycled, and so we use a local disposal service to take care of the goods.

Product Description
The Sealy Alston mattress is the top of the range model from the Advantage Collection, a range of beds designed to offer excellent support with a variety of modern fillings. At its core, the Alston mattress features Sealy's famous PostureTech spring system. These springs are made by Sealy and offer great comfort as well as support. The mesh of springs is created in such a way as to dissipate bodyweight energy efficiently and effectively, giving the body the support it needs to ensure good posture is maintained throughout the night.
Enhance Your Recovery with Edgeguard Technology
Sealy is the world's biggest bed brand and has a reputation around the globe for producing mattresses that are scientifically proven to boost recovery and enhance good posture. To provide lasting durability plus a stable sleeping surface, Sealy has provided the PostureTech springs with Edgeguard technology. This creates a strong perimeter to the mattress, allowing you to use the full width of the bed without any loss of support at the edges.
Stay Cool and Comfortable with Geltex Layers
Each mattress in the Advantage Collection has been carefully created to offer a very unique and distinctive feel. The Alston mattress boasts a deep, luxurious layer of Geltex on the sleeping surface. This material is incredibly comfortable and perfectly compliments the cushioning springs underneath. The Geltex layer is breathable and will remain cool and comfortable at all times. Unlike memory foam, Geltex does not require heat to soften and conform to the body's contours; it will do so instantly and effortlessly.
Enjoy Easy Maintenance and Premium Craftsmanship
Sealy has finished the Alston mattress in a tactile, durable and breathable fabric that adds a final flourish of luxury to this excellent bed. This is a no-turn mattress, only requiring rotation once per season. While it only needs spinning around rather than flipping over, we recommend doing so more regularly in the first weeks after delivery to ensure the fillings settle evenly.

Key features of the Sealy Alston
Progressive spring support with strong edges, topped with Geltex.
EdgeGuard
Many people complain that the edges of mattresses aren't supportive enough. Sealy has resolved this by introducing EdgeGuard technology, which strengthens the mattress's sidewalls, allowing you to sleep right up to the edge without fear of rolling off.
Spinal Support
Sealy's PostureTech CoreSupport springs are engineered to provide progressive support throughout the mattress as you sink in. Heavier areas of the body will receive additional support as they sink deeper. Sealy's springs are developed based on scientific research.
Geltex
The Alston mattress features a thick layer of comfortable, supportive gel-infused foam. This design not only offers luxury but also provides a temperature-regulating sleeping surface that enhances your sleep quality every night.
