Why Our Sleep Experts Loved It

becky says

Part of Mammoth's perfectly-designed Rise mattress range we're looking at the new Rise Plus Ortho. This product is specially crafted for those looking for orthopaedic enhanced support and care which will help ensure you get the best sleep regardless of any back or neck pain you currently suffer.

Starting with the comfort layer, the Mammoth Rise Plus Ortho Mattress features an impressive 40mm of Medical Grade™ Foam which offers deep and luxurious softness that is highly breathable and makes for a refreshing and relaxing sleep experience. Sinking into Medical Grade™ Foam is a similar experience to that of memory foam but with non of the heat build up and retention that typically occurs with that type of layer.

Onto the support layer and we're seeing a base foam layer which is both sturdy and supportive. My personal preference is for pocket springs rather than foam but other peoples mileage will vary. The benefits of foam over springs is that foam can be rolled which, as is the case here, means you get your mattress delivered in a small box. The benefit of rolled bed-in-a-box is that you save quite a large amount of money over traditional mattresses as logistics and delivery costs are absorbed far easier allowing those savings to be passed onto the consumer. The end result? A cheaper mattress of equal quality to more costly competitors.

The supportive base foam is of a firm tension which is typically going to be more suitable for those looking for additional neck and back support of the orthopaedic variety. That said, the 40mm of top layer comfort does a great job of ensuring that the mattress remains soft and comfortable.

Finally the Mammoth Rise Plus Ortho comes with an impressive 10 year warranty which is significantly longer than the average mattress lasts and shows just how much confidence and quality goes into this product. Further to that, the costs of the product become far more reasonable when you consider the lifespan is pegged at nearly double that of other lower quality mattresses. Doing so actually makes this an outright bargain.

How does it feel?

Firmness of The Mammoth Rise Plus Ortho Mattress depends on bodyweight. Adjust your weight below to get an indication of how it may feel. Remember though that firmness is entirely subjective.

Reasons to Buy

Mammoth mattresses are the perfect choice for anyone seeking a better night’s sleep and enhanced comfort. These mattresses are made with a deep 4cm comfort layer of medical grade foam, which is naturally cooling for a fresher sleep. In addition, that medical grade foam provides pressure-relieving postural support with three support zones to ensure body weight is evenly distributed across the mattress. It's a great option from a popular and longstanding manufacturer.

Reasons to Avoid

The mattress is actually quite heavy despite the lack of springs. This represents a minor inconvenience as the mattress does not come with turning handles that are fairly commonplace in the industry.  While flipping is not required on this single sided comfort layer, you should still consider rotation in order to prevent uneven settlement which would otherwise lead to premature dipping. As far as downsides go, it's a minor one and we certainly feel the pros outweigh the cons in this instance.

Key Performance Indicators KPI question mark

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews. For example, a firm pocket spring support layer is more breathable and offers better back support but may prove unsuitable for side sleepers, the reverse is true for a soft-medium tension reflex foam support layer. This is one of 100+ datapoints considered when generating the below ratings.


*Assuming average weight, suitability will vary dependant on body type, use the quiz above for a more tailored guide.
  • Back Sleepers
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.


  • Breathability
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Stability
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.

Ease of Use

  • Turning handles
  • Mattresses typically need to be rotated frequently and having turning handles can be massively beneficial, particularly in larger sizes which can become fairly heavy.


  • Initial Odour
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

  • Overall Brand Rating
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.

What Makes The Mammoth Rise Plus Ortho Mattress Great?

Part of Mammoth's perfectly-designed Rise mattress range

Scientifically proven to provide a better night's sleep and enhanced comfort

A good mattress is an investment in your health and well-being. A new mattress can help with your sleep and aid in reducing pain and stiffness. A new mattress will also ensure that you are receiving the best quality of sleep, which is essential for a healthy lifestyle.

Delivered carefully rolled up - easier for you to handle and better for the environment

Roll up mattresses, also known as bed-in-a-box mattresses are fairly new to the scene, first cropping up via the likes of Eve and Simba back in 2016. Since then there has been a rise in popularity due to their lower price point (due to delivery and storage costs) and their convenience for getting up stairs. Typically these mattresses have much the same support and comfort as a traditional mattress even with the positive points mentioned.

Due to their larger size, Superking mattresses are delivered flat and unrolled

While typically part of the new rolled collection that is both easy and convenient, the super king is an exception due to it's increased width.

A firmer feel mattress, perfect if you prefer plenty of support

Firm Tension Support Mattresses are suited to those who prefer sleeping on their front and back. Typically sleeping on your back helps ensure the spine remains aligned throughout the night and is the most natural sleeping position that can prevent twisting and turning. A firm mattress ensures that a high level of support contours around your body, alleviating pressure across your entire frame in a more even manner than that of a soft mattress, most notably in the hips, neck and shoulders.Finally, if you are suffering from neck or back pain, a firm mattress can help alleviate these problems and result in a better and more relaxed sleep for many years to come.

Orthopaedic for enhanced support and care

The need for orthopaedic mattresses is increasing rapidly. They are becoming more popular due to the growing needs of people with back problems.Orthopaedic mattresses are designed to provide support to the spine and avoid the sagging that compresses spinal discs. They are often used for people suffering from back pain who need more support and for those with a history of back problems.

Featuring a deep 4cm comfort layer of Mammoth's Medical Grade™ Foam

This is a type of material which was developed for a joint purpose between competitive sports and medical care.The foam produces a comfortable nights sleep which helps you sleep in a natural position, surrounded by softness and giving that luxurious floating feeling.Today, this foam is used by numerous medical institutions including the NHS for their mattresses due to the many real health and comfort benefits.

PostureCell technology provides pressure-relieving postural support

Three support zones ensure body weight is evenly distributed across the mattress

Zoned mattresses have springs that are divided into different zones, providing different levels of support in different areas. This can be helpful for people with specific needs, such as those with back pain or joint pain. Zoned mattresses may also be more comfortable for people who sleep in multiple positions, as they provide different levels of support no matter how you sleep.

Base foam layer is sturdy and supportive

Beautifully designed soft-touch quilted cover provides enhanced comfort

This mattress comes with a quilted cover. Many people overlook the cover as a need for consideration however, the right cover can add additional comfort and in the case of this one here, adds quilted comfort that offers a soft but hard-wearing cover that is both breathable and stylish.

Breathable air mesh cover around the border helps ventilate the mattress

The mattress comes with breathable side vents that allow the mattress to remain cool while you sleep. Another benefit to being breathable is that you naturally sweat during the night and the cool and breathable nature means that your mattress will remain hygienic for many years to come.

Hypoallergenic, helps guard against dust mites for a healthier sleep

Allergy sufferers often experience the problem of waking up in the middle of the night or having to get up in the morning with a stuffy nose and eyes. The reason why you wake up with a stuffy nose is because your mattress has accumulated dust mites, mould and mildew, all of which are allergens. The solution is a hypoallergenic mattress is made from materials that do not support mould or dust mites. They also have anti-microbial properties that effectively kill any bacteria that may come into contact with it.

Single-sided for easy care and convenience - no need to flip your mattress over

A single sided mattress is typical for the industry and relates to how  a mattress has the comfort layer on one side of the mattress. only This means that the mattress only needs to be rotated rather than flipped. The benefit of single sided mattresses is that they require less upkeep in that there's no flipping, but also, there's less components involved in the creation which saves costs.

Depth: 24cm

Most experts recommend a minimum 10 inches, 4 inches on the top layer and 6 inches for the core so this size is an ideal balance of size and performance. Generally, the heavier the load the deeper the mattress should be.

10 Year Warranty

A mattress warranty covers physical defects in a mattress, such as sagging over a certain threshold when not in use. Most mattress warranties last between 5-20 years, but as it is recommended to replace your mattress every 7-10 years this warranty will cover the life of your mattress.

Made in the UK

These are made and manufactured in the UK, meaning that they all meet the same exceptional quality and durability that we expect from genuine UK manufacturing.

Medical grade foam

This is a type of material which was developed for a joint purpose between competitive sports and medical care.The foam produces a comfortable nights sleep which helps you sleep in a natural position, surrounded by softness and giving that luxurious floating feeling.Today, this foam is used by numerous medical institutions including the NHS for their mattresses due to the many real health and comfort benefits.

Knitted Cover

It is common in the industry to have a knitted cover, these covers can come in a variety of patterns but are typically hard wearing and do not present problems for consumers.

Pressure Relief

One of the big complaints when settling into a new mattress is that it does not feel as comfortable as they hoped, where this mattress shines is in the enhanced pressure relief that it offers. Each part of your body exerts different amounts of pressure against the mattress and through the use of springs and foams, these products are able to offer significant pressure relief as a result across the entire body.


This product is unlikely to cause any sort of allergic reaction. Ideal if you suffer from any sort of allergy problems


Firm mattresses are great for those looking for an extra bit of support, either because they have a higher BMI and leanm toward the heavier side, or because they have joint and muscle pain and appreciate a decent amount of support while they sleep. If you are not actively looking for a firm mattress it may be wise to consider something else from the range that is perhaps closer to the medium firmness rating

24cm deep

A depth of 24cm is about right for a good quality mattress. While the depth of a mattress is not necessarily a guarantee of quality, you typically cannot get the best comfort and suport out of a thin mattress


Single sided means only one side is comfy. Positives are you only need to rotate the mattress occassionaly rather than the more cumbersome rotate and flip. Downside is the lifespan of the product may suffer as a result, only marginal, but worth mentioning.


Rolled up mattresses are ideal for anyone looking at trying to get a mattress up a tight staircase or in a car to bring home from the shops. Do not missunderstand just how troublesome getting a mattress up stairs can be. Heavy and cumbersome, sometimes a rolled up mattress that expands to the side of a full mattress anyway, may be the better option

Handcrafted in the UK

Handcrafted in the UK means that the product is built here, by people being paid a fair and honest wage using certified and safe products of good quality and construction. UK manufacturing is some of th best in the world and all of that is reflected in this product

Fire Resistant

Fire resistant does not mean the product will never catch fire, rather, it will not go up in flames quite so quickly. Resistant to fire in the same way that I am resistant to kisses, sooner or later you end up giving in.

Approved by the National Bed Federation

The NBF is one of the most prestigious awarding federations in the industry, helped slightly by the fact that it is one of the only, however, it is still a great source of comfort knowing that this product holds approval by the team

Customer Reviews For The Mammoth Rise Plus Ortho Mattress

Based on 9 reviews

Well made and quite comfortable. Fingers crossed it retains the support throughout the life of the mattress. Opted for medium to firm support and this ticks all the boxes. I like the fact that I can turn and move around in comfort and not sink in too much. It's supportive but not too hard. The finish is excellent. For the first time in years I am sleeping almost through the whole night! Bliss.
