Tests & Verdict

Here we collect tests, guides and product reviews so that you can create a picture of what others think about the product. This analysis and review is based on my experience and 12+ years of industry insight.

This mattress really does have it all. You're saving money through the bed-in-a-box model which will leave you with manufacturer and retailer based savings due to delivery and logistics enhancements. On top of that you have a manufacturer that flies under the radar, but produces consistently good mattresses that are well reviewed and loved by customers. The mattresses fit into the higher quality segment and so you will be paying more, but with 10 years warranty you can sleep soundly and actually, the cost per night of sleep through that period is actually quite reasonable.

Reviews are beginning to come in for this mattress but as yet there are no unhappy customers with not a single downside or negative reported. For me, I've always been a bit wary of full foam support layers as premium pocket springs have been proven for decades and why change a good thing, however, since the rise in full foam mattress in a boxes since 2016, enough time has passed to prove suitability long term. What's more, the 10 year warranty more than protects you against any unnatural manufacturer defects so you can rest assured.

Why our sleep experts loved it

becky says

Mammoth isn't a name that is very well known in the industry, often running a limited line of ranges in bricks and mortar retailers while being a bit too high brow for many in the mid-range market online. The result is a, perhaps unfair,  subdued presence in the market but by no means does any of that mean you should dismiss the new Rise Ultimate Mattress. 

Typically when looking deeper into what makes a mattress good or bad we will split the review into two core chunks, one for support and one for comfort. Let's dive in.

The support layer for the Mammoth Rise Ultimate Mattress comes in the form of Medical Grade™ Foam which acts as the support layer. The big benefit of the foam base layer is that it allows the mattress to arrive rolled in a box, helping to keep logistical and delivery costs to a minimum which can all be savings that get passed onto the consumer. The result is a cheaper mattress that performs much the same as a conventional product. Competing directly with Emma and Nectar, this support layer has proved itself and stood the test of time, being a staple of the range for a number of years and amassing a significant amount of positive feedback around the comfort provided from this type of layer. Onto the tension of this layer and you are getting a soft to medium level of comfort which will prove suitable for both back and side sleepers alike. Suitable for most average weighted people along with those that have broad shoulders and sleep on their side, the amount of sinkage into the layer should suffice to not cause your body to twist. Those of a higher BMI should perhaps consider a firmer mattress.

Onto that all important comfort layer and the Mammoth Rise Ultimate Mattress comes with a luxuriously deep 6cm SkyFoam™ layer which gives a soft and floating experience that results in an impressive cushioned and pampered feel. The SkyFoam™ layer is well reviewed across the Mammoth range with many happy customers reporting on the extreme softness and how well it moulds with the base support layer to give a great and uninterrupted night's sleep.

The layers are bound with a soft and durable cover that features an airmesh border which helps make the entire mattress breathable, helping you to keep cool while you sleep sunk into the foam. This is really important as foams biggest complaint is often around the sleeper getting too hot and so is critical in providing you with a good night's sleep.

Finally the mattress and it's components are hypoallergenic which makes it an ideal choice for those that suffer from allergies.
