The idea of buying your next foam mattress keeps you awake at night? That’s not surprising, given the number of manufacturers that all have “the best” mattress and list an incredible number of technologies in which you can easily get lost, just as we do! And if you add to this the numerous retailers offering all these brands and innovations, not to forget the huge range of prices, buying your bed seems as complex as investing in the stock market, or purchasing your first car or your first condo.

It’s enough to confuse anybody at first sight! That's why we’ve decided to give you a helping hand, as specialists in foam mattresses at Polysleep, so you can sleep peacefully like a log, once you’ll have read our ULTIMATE foam mattress guide. Really, you’ll know as much as us about this type of mattress at the end of your reading, and you’ll be able to choose yours in complete peace of mind and full knowledge of the facts!

Socrates said: Before knowing your mattress, know thyself!

It’s the digital era. That’s what we hear all over the media and this, justifiably so. You can now pay directly with your intelligent watch or your smartphone, but also count your steps or the number of calories taken per day, ask for a mortgage directly from the Internet, and contact your family travelling in Mozambique from anywhere in Quebec and in Canada with your phone. You can even watch your sleep patterns and its various stats via the numerous sleep tracking apps. You want to be more than effective at work, you want your whole life to be productive!

You can’t stop progress, the saying goes. But in the case of sleep and before you analyze a bunch of numbers on your smartphone, don’t forget the essential: owning a good mattress to sleep well! To the question, “Siri (or Ok Google), what is the best foam mattress for me?”, Siri (or your Google Assistant) won’t be able to answer. That’s where our guide will help you with the existential question: “Siri (or Ok Google), which foam mattress should I choose?”.

And that’s where things get hairier, or at least apparently. Because the criteria to consider in choosing your foam mattress are logical and simple in fact. And they all have to do with the shape of your body. You don’t select your shoes without taking into account your feet size. The same goes for your mattress. And by body shape, think height and weight. So, if you’re bulkier than average, a mattress that offers firmer support is the priority. Are you tall? Relax. Our advice is to choose a mattress providing just enough softness to be comfortable, and just enough support so your spine is properly supported; you won’t have to tell your other half “Not tonight Dear, my back aches”. And if you’re small but full of love handles? No stress! Our advice is to emphasize your weight over your height in the equation.

But what about when you sweat your life every night? Here again, with the various available technologies in terms of foam mattresses, you’ll find the one that will allow you to sleep without dying from the heat under your comforter, summer or winter! As we were saying, “Keep calm and don't panic!”, foam mattresses can answer all your questions about these different subjects. But it can only be done if you know the various foams contained in foam mattresses, as well as their density and build. And that’s fortunate, because this is exactly what we’ll talk about below!

“Siri, which is the best foam for a foam mattress?”

“I can’t answer this question. Do you want me to open Safari?” That's the frustrating answer you would get. And that’s understandable: there is no better or worse foam for a mattress. Well yes, but it all depends on your budget! We’ll list three types of foam in terms of mattress composition: polyether foam mattresses, polyurethane foam mattresses and memory foam mattresses.

Polyether foam mattress: less expensive but also less effective and less durable.

The main feature of polyether foam mattresses is their firm bedding, which can be attractive if you’re quite the strapping man (or woman). But this type of foam doesn’t handle humidity well, and offers a rather Spartan comfort, especially in terms of air circulation. That's because this mattress foam has small holes, organized in closed cells. On top of that, its long term durability is limited. So these mattresses, often considered as entry range, won’t hold the distance if you want to use them as your daily sleeper. They should rather be used for a child's bed or a spare bed in your second home, for example in your chalet in the Laurentians.

Polyurethane foam mattress: the best of both worlds!

Polyurethane foam mattresses offer the best balance in terms of support and antibacterial as well as antifungal capacities (understand here “anti-mushrooms”), while also being hypoallergenic. Goodbye sneezes that wake you up in the middle of the night! Besides, they offer a wide choice in terms of support and comfort, thanks to the multiple foam densities available, and the various comfort zones. What is more, with their open cell structure, such as that used by Polysleep (Certipur-US polyurethane foam), this type of foam allows for better air circulation, and so less sweating for you. In addition, with its improved density, it can be firmer than a polyether mattress, but also more durable. You’ll have it both ways, in other words!

Memory foam mattress: foam from space, but not the most suitable.

Lastly, you’ve surely heard of the memory foam mattress, which often grabs the headlines in the mattress industry among consumers, of which you’re a part of. This foam doesn’t really come from space, but was designed for space travel by NASA. You’ve read that right! However, this foam has some disadvantages to keep in mind when searching for the Grail of Perfect Sleep.

The first pitfall is that memory foam is thermo-sensible (it reacts to your body heat and so embraces its contours with the pressure that you also apply on the foam). It can also retain the heat you’re radiating, which can quickly become annoying in summer for those who perspire a lot. As well, if the weather is cold, this type of foam becomes harder and will take more time to mould itself to the shape of your body. As a result, you won’t enjoy consistent comfort all year long.

“Ok Google, what is the difference between density and firmness for a mattress?”

Why talk about density? Because it’s linked to the durability of your mattress. And to the question “Ok Google, what is the best density for a foam mattress?”, the answer is that there’s no real answer. Once again. Truly, it depends on your budget, and all budgets are different. What is more, there are differences in the support you’ll obtain, depending on this same density. There are three types of density: low-density foam, high-density foam, and those with very high density (or ultra-high density).

Low-density foam: not pricy, cost-efficient, but less support.

This kind of foam is measured at a density of lower or equal to 3 lb/ft3. You’ll have guessed it, these foams are less expensive, but who says lower density says shorter service life, as well as weaker support. These foams will loose their firmness a lot faster and can flatten out. If you’re a big sleeper or you have chronic pains, this type of density is absolutely to avoid! But it also offers interesting air circulation for people who become too hot very quickly and sweat a lot.

High-density foam: pricier, but you’ll get more value for your money!

The density of these foams ranges between 3.5 and 5 lb/ft3. These are the models that offer the best of both worlds in terms of longevity and support for the price. This foam will support all your weight while preserving the integrity of your morphology. It's a win-win situation!

Ultra-high density foam: the cream of the crop, but at a substantial price.

Finally, the cream of the crop, or the foam on the foam: very high density foams. These typically range between 5 to 10 lb/ft3. They consequently improve the lifespan of your mattress, but are very expensive to make, and often provide insufficient air circulation, which created the urban legend according to which “with memory foam mattresses, you’ll feel so hot that you’ll need to drink”. Mattresses with this type of density however offer unparalleled support, particularly at pressure points.

“Siri, what is the firmness of a mattress?”

The idea under which the higher the density of a mattress, the firmer the bed, is false. Don't blush, we all though that was true! Its first a matter of perception. The proof is, there is no consistent scale to represent the firmness of a mattress. But you can always refer to the Tuck Sleep scale ratings, one of the most respected in the industry, if you like numbers. So for the firmness of your mattress, it's up to you!

“Ok Google, so what density to choose based on my body and preferences?”

Your BMI, a weighty variable in the choice of density for your foam mattress.

Ultimately, you have to look more at density as a function of your body (again and always!) and the manner in which you sleep! This way, you have to go by your body mass index, that you can calculate here. So, if the latter is inferior to 20, a low-density mattress is suitable, since it’ll be subjected to less stress related to weight. But a high-density mattress can offer the same level of comfort, while being adaptable if you change your lifestyle. If your BMI is between 20 and 30, a high-density mattress is the most suitable. For those of you with a BMI superior or equal to 30, only high-density and ultra-high density mattresses are potential options in the long term for you to get the required support.

Tell me in which position you sleep; I’ll tell you what is your density

Density is also a factor to consider depending on your sleep position. If you sleep on your side, a high-density foam, obviously memory foam, can relieve the different pressure points at the level of your hips and your shoulders. If you sleep on your back, you’ll get more choice, but it's recommended to opt for a mattress with high to ultra-high density in terms of foam, since they offer much better support of your spine in the long term.

If you sleep on your stomach, low-density foam mattresses are not an option. You risk arching your back way too much because of the lack of support. In that situation, high-density foam mattresses, or even ultra-high density, are the only choices to consider for optimal support of your spine. Lastly, if you have chronic pains, we recommend the same: only the high-density or ultra-high density foams are suitable. If for you, feeling to hot in bed or sweating more than normal is a nightmare, start by selecting an open cell mattress, or one that contains a gel layer, which helps to disperse the heat you produce.

“Ok Google, explain to me the layer structure of a foam mattress!”

We know that your head is already full of the deluge of information you’ve just read about foam mattresses. Don't stop, it’s almost over! Without delay, let's talk about structure, and more precisely about the various foam layers that make a foam mattress.

We’ll focus on polyurethane foam mattresses. Yep, we’re convinced that it's the best alternative to get maximum support in the long run, no matter your body shape, while providing optimal air circulation, all of this for a reasonable budget.

There are traditional high-density foam mattresses…

Normally, foam mattresses are made of various layers of foam with different densities. It starts with the base foam layer, which is located, as its name indicates, at the base of the mattress. Its function is to provide optimal support to the other foam layers on top of it, thanks to its high density. It’s the layer that prevents you from sinking and drowning in your bed. Next comes the transitional foam. Its unique role is to negotiate! It must in fact liberate the pressure applied by your body while allowing a gradual transfer of energy, so your movements are not felt by your bed partner. Then, it's possible, depending on the manufacturer, that a layer of open cell foam is positioned above the previous layers. It enables better air circulation and so better heat dispersion. Finally comes the cover, which might be washable or not. The latter is generally soft to the touch and allows good breathability of the other layers of the mattress.

… And there is the Polysleep Mattress!

At Polysleep, we love to do things differently. Why be complex when you could be simple? Because it allows us to innovate! That's how we continue with the principle of several layers, starting with a basic support layer with high-density foam, then a transitional layer designed for optimal comfort. But we incorporated various secret spices that make all the difference! Here, let's tell you some of our secrets: the Polysleep and Zephyr models both feature ultra-firm foam frames to prevent the mattress from flattening out when you sit on the edges, while reinforcing the overall strength of the mattress. The top layer, for its part, is made of a hybrid foam that breathes. The latter also quickly detects the various pressure points to relieve them. As for the Zephyr, it possesses a final secret! Its transitional layer contains a particular foam unit at the hip level, to provide specific support to your hips to align your spine as well as possible. A little like the cushioning in the heel of your running shoes! We also gave a thought to students and tight budgets, don’t worry! You’ll also be able to enjoy all the Polysleep comfort with our Origin mattress.

Ok! Now, we’re done! You now have in hand all the keys to choose the best foam mattress that’ll allow you to depart for dreamland in the most pleasant way. And we won’t leave you high and dry if you have questions (here is the email of our president: jcurvers@polysleep.com)!
