Product Description

THIS ITEM IS NOW SOLD OUT!



Mammoth has quickly risen to fame within the bedding World, as producers of the most innovative mattresses of recent times. Boasting the only mattress range ever to be endorsed by the NHS, Mammoth mattresses are among the most supportive and comfortable that money can buy. Scientifically proven to help you get a better nights sleep, the Mammoth Rise Essential Mattress provides incredible comfort at an incredible price!

Made using traditional mattress making techniques combined with the latest in foam technology, this medium firmness mattress provides extra support to ensure that your body is enveloped in comfort throughout the night. Blending 1000 pocket springs with the famous and well established Medical Foam, the Rise Essential mattress is a wonderfully comfortable mattress, which offers support like no other.

Proven to enhance not only the duration of sleep, this Mammoth mattress also enhances the quality of sleep. This is done by allowing you to be fully supported through the night, promoting good posture and improving blood flow and circulation. The Rise Essential will also allow you to move freely throughout the night, which is essential to a good night's sleep, and contrary to other well known 'foam' mattress brands.

Mammoth's own Medical Grade™ Foam with built-in PostureCell™ technology makes up the upper layers of the Rise Essential mattress, naturally cooling the mattress as you sleep to maintain comfort throughout the night. 1000 pocket springs in the base layer of the mattress ensures a bouncy, supportive feel for the mattress. Adding to all of this is the Zoned nature of the mattress. The lumbar region of the mattress is reinforced to provide more support to the body, exactly where it is needed. This prevents aches and pains from forming through the night, caused by a lack of support.

The Rise Essential mattress is Hypoallergenic, perfect for allergy sufferers. Complete with a soft Tencel Fibre cover that naturally cools and manages moisture, helping to create a healthier nights sleep, this mattress is pure luxury from top to bottom. As a no turn mattress, this Mammoth mattress only requires rotating, not flipping over. We recommend that this process is done once per Season, although more often in the first few weeks after delivery.

This mattress is vacuum packed and rolled to ensure quick and easy delivery and installation.

    Surprised it was rolled up!
    Wonderful mattress, but we were surprised it was rolled up. After that, it was excellent, but we could not help think some of the springs were crushed? I dont think they are, but it was still a surprise!

    Superb mattress!
    Without a doubt the best thing we've purchased in the last few years! Cannot be faulted! Our backache is a thing of the past and we cannot wait to get into bed at night, getting out of bed is a struggle!

How long does the mattress take to expand properly after delivery? I see it is a rolled up mattress?

We would suggest that the mattress is carefully opened up, and then allowed to 'breathe' for around 4hrs. After that, the mattress is good to use!

Glossary

  • 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.

  • 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.

  • Tension

    Another word for Firmness.

  • Turn / No Turn

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

  • Warranty

    Every mattress we sell comes with at least a 12 month manufacturers guarantee, though most come with much longer guarantees. To find out what mattress warranty is included with your purchase, look out for the rosette on the top right corner of the mattress page. All new goods are sold with a minimum 12-month manufacturers guarantee. Full details are available on request. In addition to the manufacturers guarantee MyNextMattress offers a limited extended mattress warranty. This warranty varies in length item by item. You must keep all your purchase records as they will be needed in the event of a claim. The warranty is applied as follows:

    • The mattress warranty is against faults in manufacture, not wear and tear or damage.
    • The mattress must always be used with a mattress protector, turned and cleaned as per the manufacturers instructions and must be unsoiled at the time that the claim is lodged.
    • The claim must be registered with MyNextMattress by email or in writing. All details of the claim must be lodged with MyNextMattress by email or in writing.

    If the claim is accepted the following process will apply:

    • We will arrange to collect the goods and return them to us for inspection.
    • The carrier reserves the right to refuse to collect items that are not packaged suitably or which is unhygienic.
    • We may require pre payment for the costs of the collection in some circumstances.
    • If we validate the claim we will contact you to arrange the replacement goods to be dispatched to you and delivered to you on a date that is convenient for you.
    • The replacement item can be any item from our then current range.
    • The difference in price from the warranty covered item is payable by you, along with the cost of collecting the original item.

    There will be an allowance granted against the replacement item according to the following scale.

    • If the claim is validated within the first two years - 40% of the original price will be credited.
    • If the claim is validated in year three of the purchase -25% of the original price will be credited.
    • If the claim is validated in year four of the purchase - 15% of the original price will be credited.
    • If the claim is validated in year five or (if warranty is for longer than five years then any subsequent year up to the warranty period) -10% of the original price will be credited.

    The warranty is only applicable to the original purchaser and is only valid if approved by MyNextMattress. It should be considered as extra peace of mind in case of manufacturing defects that arise after the manufacturers mattress guarantee has expired. It should not be regarded as a guarantee that any item will last for any particular period of time, or as a guarantee against deterioration in performance. It is in addition to your statutory rights. There is no entitlement to a cash payment in lieu of the replacement. The replacement item must be at the same or higher price than the original.
