The Hypnos Althorpe is designed to appeal to those who prefer a firmer feeling mattress. Created to offer excellent support, comfort and an orthopaedic comfort level, the Althorpe has been very popular since its introduction, and we now stock it ready for next day delivery.

The Althorpe is based around a Pocket Spring unit, which uses the Hypnos ReActive Spring System. This spring reacts according to the weight energy applied. So areas where more weight is applied will receive a firmer feel. This is achieved by creating the spring in a specific way, resulting in pressure thresholds. These thresholds are referred to as 'Turns' by Hypnos, and are incredibly clever and effective. The more compression the spring experiences, the more Turns it will go through and gradually strengthen.

The Althorpe Orthopaedic has a deep layers of natural fillings, which include British Lambs Wool and Cotton. These layers are applied by hand to ensure a consistent and even feel. This not only produces a luxurious and comfortable sleeping surface, but also increases the durability of the mattress. These natural fillings allow for excellent air circulation, providing a cool and comfortable sleeping environment.

The Hypnos Althorpe Orthopaedic mattress has a silky smooth cover material, which is a Belgian Damask of the highest quality, and is also infused with Bamboo to further aid the heat and moisture management of the mattress. The Althorpe also has air vents and handles on all sides.

Headboard & base sold separately.

    Excellent support
    Its quite a strange feeling, as the mattress is certainly supportive but it does not feel like a rock. We're very pleased and have already recommended to friends and family.

  • 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.

  • Breather Vent

    See Vents.

  • Latex

    Latex is the ultimate in luxurious natural materials (but can be synthetic in other markets). Latex is actually found in more than 10% of flowering plants around the world. About 20,000 species from more than 40 families. The Latex used in the bedding industry is taken from sustainable sources. Latex is perfect for mattresses because it is soft, hypoallergenic, natural and moulds to the shape of the body. 

    Latex used in bedding also tends to be treated in such a way that it can be used by people who have Latex allergies! The technique used is to super heat the Latex unit, freeze it, super heat it and freeze it again. Once this process is complete, the harmful chemicals released can be chemically washed off, leaving it suitable for everyone. Latex is the material Memory Foam has tried to copy. Memory foam  requires heat to mould to the shape of your body and can therefore become too warm for some. Latex does not require heat and is soft at any temperature. As a natural material which requires time and various processes to be extracted, Latex can be more expensive that its rival materials, but the comfort levels achieved are well worth it.

  • 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.

  • Orthos (Hypnos)

    Orthos is Hypnos' term for Orthopaedic. Hypnos use this term for several, Medium/Firm mattresses.

  • 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.

  • ReActive (Hypnos)

    This is the Hypnos spring unit that has 8 Turns and features Active Turns.

  • Turn / No Turn

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

  • Vents

    The small metal mesh on the side of the mattress to aid moisture and heat management.
