Product Description

This Sealy mattress has been returned to us under the terms and conditions of our sleep trial. This mattress has sustained some cosmetic damage via transit and would be sold as seen in the images above. This mattress is ready for free, 2-person delivery to your room of choice.

The Sealy Sterling mattress is part of the new Enhance Collection, a range of three beds designed to offer supreme comfort without compromising on the support or durability of the mattress. The Sterling mattress is the firmest in the range and has been created for those who prefer a mattress to be much firmer than the average. Having said that; the Gel layer on the surface is still comfortable, so sleeping on the Sterling is far from sleeping on the floor!

Sealy has used a 1000-pocket spring unit at the core of this mattress. With pocket springs, each spring will move up and down as weight is applied or moved on the mattress, allowing the mattress and its springs to mirror the contours of the body perfectly and instantly. As each spring is wrapped in its own fabric pocket, it cannot interfere with the surrounding springs and so the support offered is uncompromised.

On top of this no-turn mattress is a Gel layer that offers comfort that perfectly complements the supportive springs underneath. Gel has been used not only for comfort, but also the durability and breathability. Air can move freely through the gel, keeping it cool and comfortable at all times. The Gel is applied only to one side, as this is a no-turn mattress, only requiring rotation (spinning around) once per season.

We deliver the Sealy Sterling mattress to the room of choice for free (some geographical charges may apply) with our 2-person delivery crews!

  • Foam Encapsulation

    Foam Encapsulation is a recent addition to the bedding market. An idea designed to offer greater edge-to-edge support as well offering greater Bedstead/Slatted base compatibility.

    The idea is simple; Create a spring unit and then sit it in a 'matchbox' of Foam. As you can see in the diagram below, the spring unit is surrounded on all sides by a layer of Memory Foam. This foam gives a solid, stable feel to the mattress and allows the spring unit to be completely separated from the mattresses fillings and cushion. 

    Once the spring unit is set in the foam and the foam glued together, it can be surrounded by fillings and fibre to create the traditional look for a mattress or can be given a Pillow Top for even more comfort.
