Is the Inofia SMAX mattress the thing you've been looking for to sleep like a champ? Let's take a closer look and see what makes this mattress stand out!

Inofia is a Dartford-based, UK sleep company that produces a large number of different models of mattresses and mattress toppers, as well as several pillows.

Their products have come a long way in the last couple of years, from cheap, low-end ones, to some of the best mid-priced products on the market. The Inofia SMAX mattress is one of Inofia’s best-selling hybrid mattresses, so we tested it to give you an answer as to whether you too should join the large number of people who sleep on it.

Who is the Inofia SMAX Mattress for?

Although the manufacturer does not specify for which types of sleepers this mattress is for, we think that this Inofia mattress is suitable for side and back sleepers. On Inofia comfort scale, it gets 5 – 6 and on the firmness scale 6 – 7, and our first impression is that it is a bit softer than that, maybe closer to 4 – 5.

It is for allergy sufferers because it is made of hypoallergenic material and its breathability is good. Older children, even those with asthma, are another group of consumers whom this mattress can suit.

What do we use this product for?

We use Inofia SMAX mattress for comfort, pressure relief and support above all. This is a very comfortable mattress that, although soft, provides a good level of support to the entire body. Thanks to several layers of memory foam, the pressure relief is excellent and we believe that you will not have any problems with discomfort in pressure points.

Features you should know about the Inofia SMAX Mattress

We think that it is not enough to know just who this mattress is for and what you will use it for, but that you should also know the details. In this part of the review, we will talk more about the most important features of this foam and spring mattress.

Knitted quilted cover

We start with what is closest to your body, and that is the premium knitted quilted cover. As soon as you touch this cover, it will be clear to you that it is a high-quality cover on which you will be very comfortable sleeping. It is made of a 100 per cent natural material that is durable and hypoallergenic.

Main purpose of this cover is to absorb moisture and allow you to sleep on a dry surface. It dries very quickly, so even when you sweat, it will not be a suitable environment for bacteria and dust mites.

Although the look is less important than the above-mentioned functions that this cover has, we should not forget to mention the appearance of this cover, because it is very nicely and modernly designed. The cover is not removable.

AIRYUM memory foam

The next two memory foam layers after cover are layers of advanced AIRYUM memory foam. This layer is multifunctional, because at the same time it gives you comfort as it wraps around you, and it makes you feel cool because it is upgraded breathable memory foam, unlike many other types of memory foam.

It also affects pressure relief and as a result blood circulation is improved. Together with other layers, it keeps your spine aligned naturally.
Inofia did a truly magnificent job with AIRYUM memory foam, which is called massage foam because it is so pleasant for your body.

Support foam + individual pocketed coil springs

We still have two more layers to talk about. These are support foam layer and individually pocketed coil springs. For the support foam layer, high-density foam is used which gives firmness and support. This is a very durable layer we expect to last for a long time without losing its characteristics.

Finally, we came to the individual pocketed coil springs. You will get unique pocketed spring support because they are individually pocketed, which means that they will adapt to your every move. Individually pocketed coil springs support 5 body zones – head and shoulders, back, hips, legs and feet. What is very important for couples is that they will get a maximum motion isolated zero pressure mattress.

Medium firmness

We have already mentioned that the manufacturer ranked Inofia Smax mattress between 6 and 7 on a firm scale from 1 to 10, and that we ranked it between 4 and 5. At first, you will have the impression that this is a soft mattress, because of the hybrid medium plush surface but after a few minutes, you will feel support and understand that it is actually a medium firm and not soft.

We like that very much, because it is comfortable as a soft mattress and supportive as a medium firm. However, firmness is unlikely to be suitable for stomach sleepers.

25cm of height

25 cm is the average thickness for hybrid mattresses and many hybrid mattresses that are of similar quality as Inofia Smax mattress are thicker than that, closer to 30 cm and even higher.
But generally sleep experts from Inofia have a different approach when creating mattresses. Most of their hybrid mattresses are between 20 and 25 cm thick, and only a few models are slightly thicker so this is their approach to making mattresses.

And we can confirm to you that they are doing a good job and that 25 cm is more than enough in this particular case, because we did not have a single complaint about the thickness.

Review of the Inofia SMAX Mattress

An image of the inofia smax mattress close up side

Inofia Smax mattress is a 25 cm thick zero pressure hybrid mattress. Hybrid means that the mattress has both memory foam and spring technology, to get the best of both worlds. It is suitable for side and back sleepers because of its firmness, but also due to great pressure relief, which is necessary for side sleepers.

It has different layers of memory foam, that are in charge of comfort, and pressure relief, but also support and firmness because one of the foam layers is made of high-density foam.

Coil springs are individually pocketed, so they provide unique support to different parts of your body. Mattress contains upgrade breathable memory foam, so it is great for hot sleepers. The cover absorbs moisture and dries quickly, and is not removable nor machine washable. You have 100 nights to try this mattress, and it also comes with a 10-year limited warranty.

KEY FEATURES:

  • Size: Single, Double, Small Double, King, Superking + Additional 4 EU sizes,
  • Depth: 25 cm
  • Materials: Foam, pocket springs
  • Hypoallergenic: Yes
  • Removable cover: No
  • Care instructions: Machine-washable at 40°C. Do not iron, bleach or tumble dry.
  • Warranty: 10-year warranty
  • Trial: N/A

What we like about the Inofia SMAX mattress

What we didn’t like about the Inofia SMAX mattress

The common problems with the Inofia SMAX mattress & how to solve them

Calling anything a major problem at this price point would be nitpicking, but with that in mind, the only actual problem with this mattress is the lack of a removable, machine-washable cover. This can make it tricky to keep clean, although spot-cleaning should suffice for most people.

So, please avoid eating and drinking in bed. Tough stains will be impossible to remove.
On way around this whole thing is if you invest in a mattress protector. A protective layer should be more than capable of keeping the mattress spotless in years to come.

The best alternative to the Inofia SMAX mattress

The best alternative, in terms of money, quality and overall comfort, is definitely Inofia Memory Foam mattress.

Inofia Memory Foam

An image of the Inofia Memory Foam mattress

The Inofia company is incomparably more focused on the production of hybrid mattresses than memory foam ones, but the few memory foam mattresses they offer are great.

Double Gel Memory Foam mattress is 22 cm thick and has three foam layers – gel memory foam, visco-elastic foam and charcoal support foam.

The cooling gel makes it great for hot sleepers, which is not often the case with other memory foam mattresses.

A breathable top cover improves cooling properties even more. The visco-elastic foam gives a great bounce, while charcoal is added because of its many benefits, such as neutralising unpleasant odours.
This mattress is cosy and pressure-relieving, ideal for side sleepers and couples.

It is CertiPUR-US certified. Like most of Inofia's mattresses, it offers a super good cost-performance ratio

Stomach sleepers will likely need a firmer mattress.

What makes this product better than some other similar ones?

What generally makes Inofia mattresses popular, and so does Inofia SMAX mattress, our reviewee, better than some other similar ones is the price-to-quality ratio. Inofia SMAX mattress is by no means a cheap mattress. It is rather a mid-priced one, but the support, pressure relief, comfort and high-quality cover, among other features, are the same as like on some much more expensive mattresses.

Also the Oeko-Tex certificate, 100-night trial and 10-year limited warranty are worth mentioning as well. That is why buying this mattress overall is a great decision.

How did we test the product?

An image of Inofia Smax in a bedroom.

Since a large number of different sizes are available, many of which differ by only 10 or 20 cm, be sure to measure the bed frame well and choose the ideal mattress size. Delivery is free, and at the time of writing this review, due to the current situation, delivery excludes the Channel Islands, Isle of Man, Scilly Isles, Scottish Islands, Northern Ireland, Ireland, Jersey and Scotland.

It arrives at your address rolled and vacuum packed into a box, so be aware that you need to leave it for about 72 hours to regain its full size. During that time, off-gassing will also disappear to a significant extent, so it won't be a problem for you to use it because of that.

We could immediately notice that the workmanship is great, which is very important. Since Inofia offers a 100-night trial and free returns, we gave ourselves a few weeks to test this mattress in different ways. The final impression of our test team is that it is suitable for back and side sleepers, as well as that it will probably be suitable for hot sleepers. The balance between support and comfort is one of the main advantages of this mattress.

The roller test showed us that this mattress is durable, so we don't expect you to have any durability issues, at least not in the foreseeable future.

Overall impressions of the product after the testing

With a product such as this one, namely a consumer and budget-friendly mattress, you have to keep your expectations in check and not expect high-end performance at a fraction of the price.
With that being said, we must say that Inofia SMAX mattress pleasantly surprised us in many ways.
It is a very good choice if you are looking for a new mattress and want to enjoy all the benefits that come with it without overpaying.

Neither of the manufacturing claims wasn't outlandish or out-of-line. You will get what you pay for. But what do you think of the Inofia SMAX mattress? Let us know in the comments!

FAQs about your Inofia SMAX mattress

The best way to end this review is to give you answers to 5 of the frequently asked questions about your new Inofia SMAX mattress.

Should side sleepers use Inofia SMAX mattress?

Yes, we find this mattress very suitable for side sleepers since it will provide them with comfort, pressure relief and support.

Is Inofia SMAX mattress good for back sleepers and front sleepers?

The Inofia SMAX mattress is good for back sleepers for the same reasons as for side sleepers, but most front sleepers will find it too soft for their needs.

How do I wash my Inofia SMAX mattress?

Since the cover is not removable, you can only spot clean it using lukewarm water and mild detergent.

Does Inofia SMAX mattress have off-gassing issues?

You will encounter minor off-gassing issues during the first few days but off-gassing is not a consequence of some harmful chemicals, because Oeko-Tex certifications guarantee it is free of toxic substances.

How long will an Inofia SMAX mattress last on average?

After successfully passing our durability test and because of the 10-year warranty, we think it will last at least a decade, maybe even more, but service life also depends on many other factors.

I have more than 2 years product testing experience with The Sleep Advisors which means I have slept on, with and under more than 500 products with varying degrees of success. This is added to more than 2 years experience as a product reviewer for Closer, Heat and Grazia magazines, so I've got a rigorous process. I love sharing my sleep testimonials with our readers and hearing their experiences too.
