Product Description


Ever wondered which is the firmest Hypnos mattress? The Hypnos Orthos Extra mattress is designed to offer the very firmest feel that Hypnos can offer! It is made from natural fillings, including Cotton, British Lambs Wool and eOlus Fibres which is a smart fibre. This mattress is incredibly supportive, and very comfortable, but is recommended for those who prefer an extra firm feel! It's from the popular Hypnos Orthos collection.

Hypnos Orthos Extra Specifications

This Orthopaedic mattress is handmade in Buckinghamshire and is made using only the finest materials. It boasts an excellent Pocket Spring system, designed to support the body perfectly, at all times. This Pocket Spring unit has ReActive Spring, which not only move independently from each other but also increases in firmness as they are put under increasing pressure. This means that the areas that support the heavier parts of the body will compress more, but the spring will fight back, becoming firmer and more supportive. As each spring is independent from its neighbours, the springs can concentrate on a very specific part of the body, resulting in very accurate and precise support.

The Hypnos Orthos Extra mattress has a deep layer of natural fillings on the surface. These fillings include Wool and eOlus fibres, which work perfectly together to offer a luxurious feel. These layers are compressed to a higher density than other mattresses, thus ensuring a firmer feel than most. Wool is also completely breathable and naturally bed bug resistant. These deep surface layers are bound together by hand. This process is called Tufting and ensures the fillings and the spring unit are bound together, ensuring durability as well as a solid, stable mattress.

The cover material is a high-quality silver infused bamboo Damask. This extraordinary fabric will remain cool, dry, and also acts to encourage healthier sleep. The mattress features air vents too, aiding moisture and heat management. As a turnable mattress, this Hypnos mattress has handles for easy movement when required.

So, if you were wondering what the firmest Hypnos mattress is, you've found it! This extra firm Hypnos mattress is superb value for money, and very popular with all here at MyNextMattress, and the many positive reviews underline that it is a great ortho mattress!

Who Is This Mattress Best Suited For?

The Orthos Extra mattress is intended for those who really want a firm feeling mattress! This is the firmest mattress that Hypnos produce, and whilst it still boasts great comfort, it is certainly a very firm mattress.

Frequently Asked Questions -
10 Answers

How heavy is the king size extra firm mattress

The mattress is 45kg (approx) in the Kingsize.

What is the lead time for delivery of Hypnos mattresses?

Hello. The lead time varies but we do try and stock this mattress in all sizes.

Can you use an existing slatted frame with this mattress. The frame is 2 and a half years old?

Yes, this will be fine, as long as the slats are not more than 7cm apart from each other.

I see you offer a sleep trial, will my mattress be brand new or would I get a pre used mattress that had been returned

All of our returned items are sold throught the Clearance section of our site. Any new products will be brand new from the manufacturer.

Hello How many pocket sprung usually a mattress has? As an example an euro king size Regards

Hypnos do not state the number of springs in their mattress. They state the quality of spring used. In the Orthos Extra this is a 7 Turn ReActive Spring.

Would the orthos hypnos single mattress be good to put together as a super king (with the option of making into 2 singles if necessary)?

This can be done, but the length (head to toe) would be shorter than a standard Super Kingsize mattress by 10cm.


Yes, this option is available to select in the checkout.

Do you take away old mattress? If so is there a charge and if so, how much>

Yes we do! You will find this option in the checkout as the cost varies depending on your location.

What is the difference between the Orthos extra and the Orthos wool extra firm? Thankyou

Very little! We have had the Orthos Extra constructed to be as firm as a Hypnos mattress can be without being uncomfortable, and the end result is a very similar specification to the Orthos Wool model.

Can the delivery team also take away the old mattress that is being replaced?

Yes we can! You will find this option in the checkout, as the cost depends on your location.

  • 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.

  • 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.

  • 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.
