Product Description

Truly the most luxurious mattress in the Relyon Natural Collection. The London 2850 has a combined spring count of 2850 from the pocket springs in the heart of the mattress and mini pocket springs in the pillowtop that help distribute weight evenly, minimising pressure on the body and resulting in an undisturbed night's sleep. Cashmere and silk elevate the levels of plush comfort in this truly sumptuous mattress.

Relyon's expert bedmakers have designed the London 2850 with your luxury in mind. Spectacular layers of cashmere and silk fibres are blended to create a durable insulation layer, that also helps to support the sleeper. Each deep layer of fillings is applied by hand to ensure even distribution and durability. These layers are completely natural, breathable, and even anti-dustmite.

These luxury fillings complement the pocket springs - of which this mattress contains a whopping 2,850! The pocket spring is one of the best systems to help with posture and provide comfort to the sleeper. Not only are there pocket springs in the core of the mattress, but there are also mini pocket springs within the pillow-top layer too! These springs make for a luscious feel that is slightly firmer than a traditional pillow top but remains a luxurious, comfortable mattress to sink into at the end of the day.

The London 2850 is a no-turn mattress, with firm edge support and three rows of side stitching ensuring that you can make use of the whole sleeping area.

Relyon are so sure of the quality of their mattresses that they offer a 10-year guarantee, for your complete peace of mind. We will deliver this superb, top-of-the-range mattress to your room of choice for free to mainland UK customers.

Frequently Asked Questions -
8 Answers

How breathable is this mattress - it has no vents. Also Is it temperature regulating.

The Relyon Luxury Silk 2850 is a breathable mattress, with natural fillings and a breathable cover fabric. Also, as the mattress is a pocket sprung mattress, there is a lot of air inside too, which can freely flow through the mattress.

Where is the Relyon Luxury Silk 2850 made?

The Relyon Luxury Silk 2850 mattress is made in Somerset, England.

What tension is this mattress?

We have classed the Relyon Luxury Silk 2850 mattress as a medium mattress, perhaps on the softer side of medium. With the luxury fillings on top of the mattress, and the supportive springs inside, the combination results in a medium feel.

Can the top layer of the Relyon Luxury Silk 2850 Mattress be removed?

No, the Pillow Top layer is built in and cannot be removed.

Where is the Relyon Luxury Silk 2850 Mattress made?

  • Breathability

    Mattresses need to breathe. With the amount of fillings and areas of space within a mattress, they can quickly hold heat and moisture. Over time this can influence the way a mattress behaves and also effect the life span of a mattress. 

    Manufacturers have developed different ways of tackling the problem of Breathability in mattresses. Some brands have used vents to allow air to pass through the mattress. Some brands use state-of-the-art materials to cover the mattress, such as Coolmax or Outlast. Memory Foam has a reputation of storing heat and moisture, as foam requires heat to soften up.Memory Foam brands have overcome this problem by applying Coolmax and Outlast, they also use Open Cell technology. This technique is to simply allow the foam to settle with larger spaces between the foam cells. This allows heat and moisture to move freely without getting trapped.

    Some mattresses are created in such a way that they do not require any additional Breathability methods. These mattresses are generally the entry level mattresses with Open Coil spring units and not a great deal of fillings.

  • Fibre Most mattresses will have layers of fillings under the surface to increase comfort and separate the spring units from the surface. The most common fillings used in mattresses are cotton, wool and polyester among others. Mattresses require fillings to create a soft surface tension on which to sleep. The fillings normally compliment the internal spring unit by adding comfort to the support offered (by the spring unit) The tension of the surface fillings can be tuned by the density in which they are packed as well as by the method in which they are bound together. Tufting results in a slightly firmer feel than quilting.
  • Fillings

    The fillings of each mattress can differ from one another, but largely they include British Lambs Wool and Cotton. Some also feature Latex, Silk and Cashmere.

  • Hypoallergenic

    Put simply, Hypoallergenic materials do not cause the amount of irritation that non-hypoallergenic materials can. Hypoallergenic materials can still cause irritation in some cases, the chances of this are reduced greatly. People with severe allergies and asthma may still have problems with items called hypoallergenic, but the risk is greatly reduced.

    Hypoallergenic materials do not omit the same particles and fibres as other non-hypoallergenic materials. These particles are to blame for causing irritation and discomfort and in some cases the irritation can be dangerous. The Hypoallergenic properties of these materials can be created by number of techniques. Some materials (Memory Foam or Latex) are naturally hypoallergenic, others have been chemically treated.

  • Orthopaedic

    Orthopaedic mattresses are usually the firmest mattresses on the market. A common mistake made by those with back pain, is to assume that a firm Orthopaedic mattress will be the solution. Personal comfort and a correct diagnosis of the cause of the pain should always be saught before purchasing an Orthopaedic mattress. 

    Many brands have 'Ortho' mattresses. Terms used include 'Backcare' or 'Orthocare' and the theme is generally to produce a firmer feeling mattress. The idea is to create a mattress that the body can rest on without sinking in and bending the spine, causing pressure to build up. However, if a lighter person lays on a firmer mattress, they will find the spine will not align correctly as the loaded parts of the body (shoulders, hips etc) are not sitting correctly. For more information on the causes of back pain, click here or read about another solution in the Zoning description.

  • Pocket Sprung

    Pocket Sprung units are an adaption of the traditional open coil/continuous spring unit. By placing each spring in its own individual 'pocket' (a fabric sock-like pouch), the spring is not joined to any other part of the mattress. The pocket that supports the spring is then joined to its neighbouring pockets and this effect creates a unique feel.

    By creating a spring unit in this way, it allows the springs to move independently, rather than sharing the pressure with surrounding springs. This effect allows for much more accurate contour following and a more comfortable feel overall.

    If you were to push your hand into a traditionally sprung mattress, the area around your hand would dip/sink too. With Pocket Springs, this sunken area is much more remote and therefore more accurately follows the contours of the pressure source. There are differences in the techniques used to create Pocket Springs, but more or less they remain the same.

  • Side Stitched

    Side Stitching is the way in which the side of a mattress is finished. A traditional process, the Side Stitching technique applied by many high-end companies, is a highly-skilled profession and takes time and a great deal of experience to perfect. The technique involves passing a needle through the side of a mattress right the way through to the horizontal surfaces for additional strength and stability. This technique is normally the reserve of expensive, high-end mattresses.

    Another technique applied more commonly in mid-range mattresses, is to simply attach the stitching to the spring unit in the mattress. Other manufacturers may simply use a material on the side of the mattress which appears to be side stitched, but actually is not.

  • Tufted

    Tufting is a traditional and highly successful way of finishing a mattress surface. The end result makes the mattress appear to have dimples, or buttons dipping into the surface. This technique is designed to hold the surface materials together and to fix them to the core of the mattress to prevent the layers moving over time. A modern method is Spiral Tufting, which involves fixing the surface to the fillings and spring unit.

    The actual tuft is usually made from a cotton felt material and is fastened by a cotton or wool chord to the spring unit, in most cases. A tufted mattress will normally have a firmer surface than a non-tufted/quilted surface. The reason for this is that the Tufting process actually holds the surface material and underlying fibre layers tightly together. This will create a tighter, firmer feel than a quilted mattress.

  • Turn / No Turn

    Some mattresses require turning over, to aid even settlement. Others do not require turning, but will still require rotating.
