Product Description

The Relyon Bristol Ortho 1500 is a fantastic orthopaedic mattress from Relyon, one of their firmest mattresses and one of our best-selling ortho mattresses. 1500 Pocket Springs, natural fibre fillings and superb hypo-allergenic Superflex foam are all handcrafted together to create a superb extra-firm feel mattress. This mattress is designed for those who want their mattress to be very firm.

Relyon's 1500 Pocket Springs move independently from one another to support your body as you sleep, helping to distribute evenly and increasing postural support as a result. Each spring moves up and down like a piston, mirroring the contours of the body instantly to provide support where required, and preventing pressure points from forming - the main cause of aches and pains.

Hypo-allergenic Superflex Foam adds an extra layer of support and helps reduce the effects of dust mites, which cannot survive in the foam. This foam is not only supportive, but it is also very comfortable and will gradually conform to your body's shape, working in harmony with the springs at the core of this Relyon mattress. The edges of the Bristol Ortho 1500 are supported with firmer springs, adding strength to the sides of the mattress and increasing the usable area of the mattress by up to 15% (in a Double size), meaning you are supported no matter where on the mattress you sleep.

A deep cotton layer is used to complement the springs and the foam, allowing for a comfortable feel for the mattress, whilst three rows of side-stitching make for a robust, durable mattress. This mattress is traditionally hand tufted with wool tufts, securing all fillings in place and providing a perfect finish to the look of the mattress.

This is a turnable mattress and comes with an 8-year guarantee from Relyon.

  • 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.

  • Delivery

    Our deliveries are carried out by a small courier outfit called BJS Distribution. We use this company for all Double and Kingsize mattresses and Divan Beds. This service will see all goods taken to room of choice and unpacked, all packaging can be taken away for recycling (upon request). We use NIghtfreight for our smaller products (pillows and headboards etc). Delivery to the room of choice is free!

    We operate a next day delivery service on all our stocked items. If you order before 13:00, you can receive you new mattress, bed, pillow or headboard the following day. Delivery is free!

    Our couriers will speak with you to arrange a delivery timeslot, and also offer an hours notice within this timeframe. With smaller items, on Nightfreight's service, we offer 30mins notice ahead of arrival.

  • 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.

  • Firmness

    MyNextMattress is developing a new and unique solution to the Firmness scale accuracy. Not seen anywhere else in the World, we will be measuring the Firmness of all our mattresses precisely and in detail.

    We are the only company in the Country that will actually measure the Firmness of a mattress and give a grading out of 10. We are always aware that choosing your next mattress can be a difficult and time consuming process, therefore we strive to give as much information as possible on every mattress we sell.

    The way our system works is by applying weight to a mattress. We will apply weight gradually and measure the amount the mattress dips. The more weight, the more the mattress will 'sink'. We would then measure the distance the mattress dips and plot these measurements (weight and distance) on a graph. This graph can then be used to tell us the Firmness category the mattress fits into, 7 out of 10 for instance.

    Our Firmness Device provides a central rod which we apply weights to, on the bottom end there is a disc which pushes into the mattress. The top of this rod supports the weights and will sink according to the 'give' in a mattress. We measure from this point.

    As a result of this unique technique, it will be possible for you to shop by the firmness of a mattress, this is not possible anywhere else.

  • 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.

  • 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.

  • Pressure Points

    Pressure Points are created in the body when lying on a mattress which is not suitable for a persons physique. The Pressure Points are caused by putting stresses through the body. When the spine is not aligned correctly (i.e, straight), it can cause pressure to build up in the back, hips or shoulders (etc).

    When a bed is too soft, the body sinks in, causing certain areas to be under the strain of the rest of the body. When a mattress is too hard/firm, then the weight applied can cause the body to flex/bend in the opposite way - causing a similar problem. Hips, shoulders and so on, are requried to be sunken into the mattress slightly more than the surrounding areas, as they carry the weight. When this is not the case, the lower back may be bent to compensate. The ideal mattress is one which will keep the spine straight.

  • 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.
