The Ergoflex 5g UK MattressDisclaimer: This is my personal honest review of my Ergoflex Mattress. I bought the mattress myself and after my unboxing video Ergoflex refunded my payment without request from me. They stated they were now supplying mattresses for free for online reviews and refunded me simply as a goodwill gesture. They have made no requests on what I do and say in this or any other review. They have allowed me an affiliate link which means if you buy via my link I get small commission and you pay no extra.
The Company: Ergo Flex LtdThe company behind Ergoflex was formed in March 2007. The same directors listed when the company was formed remain in place today at the time of this review. They are Jack Margaret and Gerald Macewan.

The Ergoflex 5G Mattress – OverviewThis is all about the quality of the memory foam and whether as the marketing suggests Ergoflex is the nearest bed in a box option to buying a Tempurpedic mattress. It must be understood what makes Tempur the leading brand for memory foam and why you pay the high price for a Tempur mattress. There is of course a certain premium for the name but Tempur have in the past been known for their high density memory foam. Density matters because the higher the density (the amount of foam contained within a certain area) the better the longevity will be as it will be more durable. So it will last longer and hold its properties longer. Tempurpedic were of course the originators of the commercialisation of memory foam, a product developed by NASA in the 60s for astronauts and so have a long history of developing and perfecting their memory foam. In its simplest form memory foam is polyurethane foam with specific additives to create a foam that responds to body heat by molding around the points of pressure. Normal polyurethane foam compresses under pressure and stores that pressure as spring back thus memory foam has less push-back than a normal foam and the reason why hospitals use it to reduce bed sores. So my point here is that to challenge Tempur a company must have a memory foam of 70 kg/m3 plus and must use a significant amount of it and it must be the top layer of the mattress. Ergoflex used to advertise their foam at 85 kg/m3 which would be near the same used in the past by Tempurpedic. However for commercial reasons they no longer advertise the density and I must go by weight to make a guess at what is being used. Ergoflex with 9cm of still high density (see my testing below) memory foam do indeed on paper provide a value for money alternative to Tempur. I want to point out that the memory foam used is of the traditional type, as it should be if you want the full benefits of memory foam. By this I mean it has the classic sticky molding feel as you push down with a slight delay in response. Many companies advertise memory foam but its more of a hybrid designed to provide more spring back and faster response. However by doing this they are negating some of the very benefits people are looking for from memory foam. Companies will advertise their mattress as using memory foam but that layer is under the top layer. This means it cannot act like a memory foam by reacting to your body heat and I do not consider them memory foam mattresses. Also watch for the depth of the layers used which are often no more than 3cm or so. Again you will not get the benefits of memory foam with such shallow layers. In terms of my Ergoflex overview Ergoflex do have next day delivery which isn’t something all the online mattress companies offer. Delivery is free unless you want next day for a Saturday in which case there is a £35 charge. The mattress will of course arrive in a box which you open and then pull out the vacuum wrapped mattress. Ergoflex go beyond the certiPur certification which some mattresses (but not many) offer with Oeko-Tex certfication which covers the whole mattress, not just the polyurethane foam layers. Something which Tempur do not offer at all. Ergoflex also offer what they call their white glove service. This is a two man team who deliver to your actual bedroom, unpack the mattress and take away all the packaging. You must ask for a quote if you need this service.
The Ergoflex 5g Mattress Layers:
The foams used all have both CertiPur and Oeko-Tex certification for no harmful chemicals and controlled amounts of other allowed chemicals. Oeko-Tex goes further than CertiPur as covering the whole mattress and all materials used including even the zip.
It is great that Ergoflex have gone for Tencel in their mattress cover, Tencel being a natural product made from wood pulp with great breathability, hypoallergenic and wicking properties. However it should be noted that the cover is actually a blend of Tencel and Polyester with polyester being of course a petro-chemical product. The majority of competitors do use a 100% polyester cover with no Tencel at all. Ergoflex does however have Oeko-Tex certification which certifies the cover amongst all other elements as having no harmful chemicals. The cover is fully removable although to do so you need to unzip it from the very bottom of the mattress. The cover is also washable at 30 degrees, this is often not possible with other mattress covers. One thing to note is that while the cover itself is deliberately super thin to aid heat transfer there is a protective stocking between the cover and the mattress. This negates to some degree the benefit of having such a thin cover.
When buying the Ergoflex mattress you will first and foremost be buying it for this top memory foam layer. A full 9 cm of full-on memory foam, not a hybrid as often used where it is a balance between normal polyurethane foam and memory foam to offer more response. When you lay on it you get that traditional memory foam feel of very slowly sinking in and molding. The degree to which you feel that sinking will of course depend on your weight. Lighter people will not have such a sinking sensation as heavier people. Because this is a higher density than often used on bed in a box mattresses it also has a firmer feel than you might expect, unless you have tried some Tempur mattresses too. Ergoflex no longer publish the density of this layer. It used to be 85 kg/m3 and while it might be slightly lower now (I can only guess by weighing the mattress as a whole) it is clearly still of high density judging by the overall weight of the entire mattress (including the non-memory foam base layer) and its excellent average overall average density of 50 kg/m3. This is around 20% better than all the other memory foam mattresses I have tried.
While I talk about the memory foam on Ergoflex as being of the traditional type it is quite responsive and not the stuck in quick sand type of years ago. I would hope anyone buying a memory foam mattress would be aware of potential heat issues It is worth pointing out that memory foam works by reacting to your body heat and by nature will tend to sleep hotter than other foams. The layer below hopes to alleviate that to some extent with its castellated foam.
As with all layers the foam is CertiPUR certified and also covered by the Oeko-tex 100 standard.
The foam used is described as ACPT™ foam. This stands for advanced cellular polymer technology. It doesn’t seem to mean anything specific other than a description of the foam itself.
In my own experience after a solid 4 weeks of sleeping on the mattress I found almost no change in the firmness at all. This is great. The most common issue I normally notice is localised softening at the points of highest pressure, a 1.5 cm change in firmness over a 4 week period not being uncommon. The Ergoflex memory foam mattress was almost exactly the same firmness at the time of this review as when I first lay on it. This is the benefit of higher density foam.
The transitional layer is 5 cm of polyurethane foam. The thing to note here is the convoluted design. The egg crate shape cutting allows for air to circulate and thus help with cooling as it allows trapped heat to escape as well as fresh air to circulate. It is something Tempur also do. The downside is that it does mean foam has been removed and thus makes it weaker than it otherwise would have been. This is the same issue as when used for zoning on the base layer as we often see with other brands. Note though that Ergoflex does not have zoning as such so the use of this convoluted layer is no different to most others using a layer of this type. The layer also aids transition from the softer memory foam layer to the firm base layer.
This is the firm base layer. The density will be lower than those above and is here to provide support, nothing else. In effect it is the layer than actually holds you up. Being part of the mattress it means this is a no flip mattress, you are not meant to sleep on this bottom layer.
Ergoflex Mattress Overall:
There is effectively 14 cm of comfort layer on the Ergoflex if you count both the top and middle layer. This is significantly more than most online competitors and while it does not make the mattress softer it does aid longevity as it is the comfort layers that soften the most over time.
Total height with cover: 23 cm (9 inches)
This is a great density. Most online mattresses are around 40 kg/m3. Only Bruno and Leesa Hybrid have been around this mark. This shows that true high density memory foam is being used and promises good durability for the mattress.
One issue with mattresses is the variability in size. My Ergoflex mattress was very good for being within spec at 191 cm of the specification of 190 cm long. So almost bang on spec.

Ergoflex Mattress – Tests and Analysis:
I found the Ergoflex to have decent edge support. You have to be realistic with a foam mattress that it will give as you sit on the edge. In my tests i had an average dip of 33% for a variety of weights which is a good result. It means for most sleepers they are not going to experience a roll off effect as they sleep towards the edge. Of all the mattresses I have tested only the Leesa Hybrid mattress was better for edge support.
Firmness (how far it sinks for a given weight):
In terms of the memory foam mattresses I have tried Ergoflex is a little firmer. Certainly firmer than Nectar AFTER they have been broken in. I always allow about 4 weeks to break in a mattress to see what the firmness will likely be long term for most people of average weight. In almost every case they soften up around the areas where it received most compression, for a back sleeper this will be at hips level. Ergoflex did not soften up which is good. It means the firmness level was more consistent which is important because the trial period with Ergoflex is 30 days not the 365 nights of Nectar or 100 nights of many other online offerings. My scores for firmness are all after break in which is important to remember. Another thing to note is memory foam will go on sinking for a period of time after you have been laying on it. Know that my firmness scores are an average taking a measurement over a period of time. Also remember memory foam requires heat to soften up. If you have lots of sheets on top of the mattress it will feel firmer than if you lay closer to the actual memory foam itself. It will also feel firmer in a cold room than a warm room. I have to give a single guide score but you must take all these factors into account. Ergoflex 5G sits around midway of mattresses I have tried firmness. Overall about the same softness as the Leesa original. A bit firmer than the Vesgantti Luxe Hybrid, Simba Hybrid and Nectar mattresses. Noticeably firmer than then Casper Mattress and Una Mattresses. Softer than the Leesa Luxury Hybrid and softer still than the Emma Original and Otty Hybrid mattress.
It is just an inherent property of memory foam that it will have some heat build up. Some companies try and use gel to lessen the affect or try and make the foam with larger than normal cells. However they all still have heat issues if you are sensitive to this issue. In the case of Ergoflex they have castellated foam beneath to increase air flow and help with the escape of trapped heat. There is only so much anyone can do though because good quality memory foam has to absorb heat to work. Memory foam therefore is not the best option if you are sensitive to sleeping hot.
Spot Relief (point elasticity):
Point elasticity is the ability of a foam to respond to pressure and only give at the point the pressure is applied. Memory foam excels at this making it highly molding and contouring. This ability to contour just around the body parts pressing into the mattress combined with its lack of push-back makes it great for painful areas. As expected Ergoflex does really well in this area with about the same point elasticity as Eve and just behind Nectar, Emma original and Bruno. Better than Casper, Leesa, Simba and Leesa Hybrid.
Mattress for Sex/Bounce:
The Ergoflex mattress has almost no bounce. If you bounce a ball or fall onto its surface almost all the energy is absorbed into the memory foam as a good memory foam would. This means in terms of the best mattress for sex if bounce is part of the equation Ergoflex is not great in this area. All other mattresses I have tested have less bounce. The Leesa Hybrid, Otty and Casper mattresses remain my top rated as a mattress for sex.
The maximum recommended weight per person is 18 stones (114 kg or 252 lbs) or 30 stones for combined weight (190 kg or 420 lbs).
This is where the Ergoflex 5G mattress really excels. Being a true memory foam mattress means you get all of those motion transfer qualities you see people rave about on the Tempur mattresses. This is the best mattress I have tested for motion transfer. Even on my heaviest weight test there is virtually no motion transferred elsewhere across the mattress. If you feel your partner turn constantly in the bed and this is a problem for you then Ergoflex will be an excellent option. Better than other memory foam mattresses such as Nectar and of course better than the other non memory foam mattresses too.
Type of sleepers this mattress suits:
This can only ever be a very general guide based on average weight and size. The fact is back sleeping is quite tolerant of firmness level while side sleeping requires a softer feel and stomach sleeping requires a firmer feel. Ergoflex is quite a middle ground mattress in feel but how it will feel to YOU will depend on what you are used to and your personal preference. I would class this as a medium firm mattress.
I can only go by advertised retail price here. However it is rare to pay full retail price for a mattress these days. Ergoflex like many other online companies have seemingly permanent special offers. Very good offers at that with currently £200 of a full size mattress. This is a great offer which means although the advertised prices are at the high end of these online bed in a box companies the actual price you normally pay is at the bottom/low end.
When it comes to a memory foam mattress density is important. On this basis alone I would have to score Ergoflex highly, it genuinely does deliver a lower price option to the Tempur range. It uses a significant depth of high density memory foam and this is rare for a bed in a box online offering. On top of this the foam is CertiPur certified for low VOCs and no harmful chemicals and also Oeko-Tex certified for the same criteria covering the whole mattress. The cover is is removable and washable another big plus which is not as common as you would hope it would be amongst the online mattresses. Tencel for the cover is great albeit a 41%/59% Tencel/Polyester blend. Additionally I noticed no localised softening in my 4 weeks of breaking in.
There was a noticeable odour on first unwrapping the Ergoflex mattress. This diminished over the weeks I have slept on it and at the time of the review there is just a small odour if you smell very close up to the mattress itself rather than it filling the room.
All mattresses soften up. The rate at which they soften up is the differentiating factor. Eergoflex 5G had no measurable softening in the 3 weeks I slept on it. A great result.
Alternative good mattress for softening: Otty Pure Hybrid Mattress
I do not score this criteria because it is 100% subjective and does not reflect any real qualities of the mattress. Of course the mattress you choose needs to be comfortable to you but it also must not result in aches and pains after 8 hours of sleep through sleeping out of alignment. Someone describing a mattress as comfortable with a suggestion that it would then be comfortable for most people is very misleading. Comfort is very much a learnt thing often based on what you have been used to rather than what is good for you. For me I would say I found Ergoflex comfortable and supportive as a side and back sleeper and is at the top end of firmness that I could still happily sleep on. When I tried it with a decent quality memory foam topper I found it was a good match and I slept happier with the extra layer of softer comfort foam.
There is no specific zoning in terms of making areas softer than others. Zoning is a not a make or break design element and if done badly can make things worse. The normal method of cutting channels out of the base layer also leaves it weakened.
