How to choose the ideal mattress for a bed?

A very recurrent question on websites and online search tools is: how to buy a mattress? Since we spend a third of our lives lying down, recovering energy for the next day, the mattress we sleep on should be as important as a good breakfast or exercise. With that in mind, we've put together a very detailed shopping guide with the steps needed to choose a good mattress!

Although the brand is an important factor in the decision, as well as the trust you have in it, it is necessary to pay attention to other aspects as well. So in this guide we will separate the steps into 5 mattress characteristics: size , comfort , density , structure and differentials . Zoom in more detail below:

Mattress Size
Mattress size varies according to the profile and budget of the person who will sleep on it. Another limiting factor is the ideal type of bed: it is suggested to choose a mattress 2 cm smaller than the size of the traditional bed, which does not apply to the box bed, as the mattress must follow the same measurements for a perfect fit.

It is also important to remember that the ABNT (Brazilian Association of Technical Standards) determines that the size of the product can vary by up to 2cm in manufacturing measurements, and that is why some brands manufacture exclusive measurements, such as Ortobom , which provides more comfort and space for your customers. We will list below the most sold sizes in Brazil, followed by measurements and indicated audience:

Child

From cribs to children's beds, the mattresses that vary the most in size are those from the beginning of life. In the case of berths, the minimum size is usually 0.60 x 1.30 m. For older children, the measurements can reach 0.70 x 1.50 m, depending on the size of the bed.

Not married

Designed for those who sleep alone, the dimension is 1.88 x 0.78 m (Length x Width), and can vary by 10 cm, reaching 0.88 m in width, depending on the bed. The ideal type of bed for the thinnest single mattresses is bunk beds or narrower beds.

Widow

The intermediate version between the single mattress and the double mattress is popularly called the “widow”. This type of mattress is narrower, is 10cm less wide compared to a double, and provides more comfort for those who sleep alone and even for a couple. The size is usually 1.88m x 1.28m.

Couple

For two people and smaller spaces, the double mattress is ideal. Dimensions are 1.88 x 1.38 m (Length x Width).

Queen Size

Wider and longer than a double bed, the Queen Size , translated as "queen size", is perfect for the couple who like more space or who have children in the family. It's ideal for tall people too, over 6 feet tall, who don't fit the mattresses above. Its measurements are 198 x 158 cm (Length x Width).

King Size

Made for tall, wide people and large families, the King size is the largest mattress available on the market. It is very spacious and can be found in 2 different sizes: the King Size , with 1.98 x 1.86 m, and the Super King Size, with 2.03 x 1.93.

Comfort of the Mattress

Another very common question is: what is the most comfortable mattress ? The types of comfort vary according to the raw material from which the mattress is made, in addition to the spring structure. Below we will mention the different raw materials used for each type of comfort, and for which profile it is suitable.

Extra-soft comfort
The extra-soft mattress is suitable for bedridden people, but under medical supervision. It is not suitable for those who have a previous condition in the spine, as the lack of rigidity makes the body curved. Usually this type of mattress comes with double layers of springs or layers of memory foam in large quantities, increasing comfort even more. The purpose of memory foam mattresses is to mold themselves completely to the body, not causing pressure against the weight, but totally absorbing the person's body into the mattress.

Soft
Much like extra-soft mattresses, soft ones also cause the body to sag and are not suitable for anyone. They are suitable for singles, preferably children and teenagers, who weigh less than an adult. Generally, the soft mattress loses support over time, and the rotation (changing the mattress of position) becomes mandatory, in case it starts to cause pain in the body. It is also worth remembering that the most common springs in this type of mattress are the bonnel and individually bagged . We'll talk about the different types of springs below in the Mattress Structure section .

Comfortable/Average

The comfortable/medium mattresses are a version of the soft spring mattresses with a smaller amount of viscoelastic and a larger amount of latex. This type of structure makes the mattresses have a greater uniformity when in contact with the body weight and that they last longer. Integral latex mattresses (100% natural latex) from some brands are comfortable and of high quality and durability. They are recommended for tall and/or broad couples or adults.

Firm comfortable
Comfortable firm mattresses are the top sellers for couples, as they are more resistant and provide balanced comfort. Most firm comfort mattresses use high-density polyurethane foam supported by individually bagged springs, such as LFK and Miracoil springs, for example. This type of mattress lasts longer due to Inmetro certification that guarantees the quality of the foams used, added to the good quality springs. These factors make the firm comfortable mattress have a longer service life. Despite having a high cost, the quality is also superior when compared to other types of comfort.

Firm

Many physiotherapists recommend the use of firm mattresses for those who have scoliosis and low back pain problems. These mattresses, made of polyurethane foam, are the most sold types in the Brazilian market for having a more affordable price and the appeal of being semi-orthopedic mattresses, which are good for the spine . We know today that having a little comfort is even recommended to keep our spine healthy. Some brands use spring mattresses for firm comfort, but add a wooden box to the pillow top to make it more supple.

Extrafirm
The extra-firm mattresses are made with wood sheet and/or Styrofoam (EPS), and give the feeling of sleeping on the floor. This type of comfort is for those who are already used to this hardness, considering that some studies reveal that this type of comfort does not bend in important points of the body, such as hips and shoulders.

Mattress Density
When shopping for foam mattresses , it is important to be aware of density related to your weight and height. The definition of density, when we talk about mattresses, is the amount in kilograms of foam per cubic meter. In other words, for a mattress of density 33 , or D33, 33 kilos of raw material were needed for each cubic meter. It is important to know how to choose the density to prevent a person of greater weight from sinking, deforming the mattress or compromising health.

Choosing density is not a difficult task, and there are online calculators that will tell you the ideal mattress based on your weight and height. Every biotype table comes with a referential asterisk of “preferably”, as this is not an absolute truth and does not take into account more than one weight on the mattress. If you want your mattress to last longer, consider taking a mattress with a comfort that suits your body and with a high density. Below are the 8 types of density available on the market:

• Mattresses with D18 AND D20: newborns weighing up to 15 kilos.
• Mattresses with D23 : people up to 50 kg and up to 1.70 in height or people from 51 to 60 kg between 1.71 and 1.80 in height.
• Mattresses with D26 : suitable for people from 51 to 60 kilos up to 1.70 in height or people from 61 to 70 kilos between 1.51 to 1.90 in height.
• Mattresses with D28 : suitable for people from 51 to 60 kg and up to 1.50 in height, people from 71 to 80 kg between 1.61 to 1.90 in height or people from 81 to 90 kg above 1.90 in height .
• Mattresses with D33 : for those who are 71 to 80 kg between 1.51 to 1.60 in height, people from 81 to 90 kg between 1.61 to 1.80 in height, people from 91 to 100 kg from 1, 81 and above 1.90 in height or people from 101 to 120 kilos above 1.90 in height.
• Mattresses with D40 : suitable for people from 91 to 100 kg between 1.61 and 1.80 in height, people from 101 to 120 kg between 1.71 and 1.90 in height or people from 121 to 150 kg above 1, 90 tall.
• Mattresses with D45 : for people from 101 to 120 kg between 1.61 and 1.70 in height or people from 121 to 150 kg between 1.71 and 1.90 in height.
• Still in doubt about choosing mattress density ? In the Biotype Table , from the National Institute for the Study of Rest (INER), we can identify the most suitable density for all people:

Mattress Structure
The mattresses are made in different structures and have listed above some of them, such as foam , Bonnel spring , bagged spring and Verticoil spring . Here we will explain to whom they are indicated, their characteristics, differentials and cost.

Foam
The foam mattress is very popular and the cheapest compared to other structures. It has no metal or wooden structures, just polyurethane foam. It has a greater range of models, which serves a larger audience with significant differences. It is important to pay attention to price, quality and density. The latter has already been addressed here, mainly in the INER biotype table, which indicates the ideal model based on its weight and size. Ah, it is usually indicated for those looking for more firmness in supporting the body, not softness.




Springs
After foam, the spring mattress is one of the most sought after. This yes is indicated for those looking for softness; it still has greater strength in supporting heavy bodies. Spring mattresses have a different relationship with density, and the subtypes differ by the maximum supported weight, as listed below:

Pocket Bag Springs

The pocket springs, pocket springs or , using a manufacturing technology in which each spring acts individually. With this they do not interfere in one person's region if the other moves on the other side. Therefore, they are ideal for couples or those people who move around a lot in their sleep.

• Bonnel or Prolastic Springs :one of the cheapest spring mattress types, theBonnel modelsare a structure formed by several hourglass-shaped carbon tempered steel springs, connected to each other. Despite providing a firm, comfortable, and durable base, they are often noisy, as the pressure when moving causes their entire length to move. This can be a problem for those who share a bed (or an irrelevant detail for those who are deep sleepers).
• Nanolastic spring:thenanolastic springhas the same characteristics as Bonnel springs, with the difference that it has a smaller carbon molecule. Depending on the brand and manufacturer, this can make a difference in noise reduction.
• Superlastic spring :like the nanolastic, the superlastic spring has a structure very similar to the Bonnel spring, with the difference in the shape of the wire, which is spiral. This factor makes them firmer and support more weight, up to 150 kg. However, the same noise and motion issues are present in this model.
• Verticoil spring :also a variation of the Bonnel spring, theVerticoil springis distinguished by having more springs per square meter, which reduces the "scale" effect. Remembering that the noise still remains.
• Hot Melt Spring: the Hot Melt springs are distinguished by hot melt adhesive track (or thermoplastic) glue the foam springs and coatings, providing better quality, longevity and less odor to products. The adhesive is used in a liquid state and re-solidifies on cooling, allowing for better adhesion to the springs.

Mattress Differentials
In addition to all the above factors that integrate different mattress models, they can still come with considerable differentials. Let's mention some extra features that can stand out when choosing, contributing to an even better sleep:

Pillow Top, Euro Pillow and Orto Pillow

Pillow top means “pillow cover” and is an extra layer on top of the mattress. It is usually made of a different material than the one used in the mattress body, with a higher resilience foam. The different types of foam are: polyurethane, gel, viscoelastic and hyper AMX. It differs from Euro Pillow in that it is thinner. Already Ortho Pillow has comfort firmer and reinforces the support of the mattress, helping to reduce pressure points. These layers provide reinforcement to the mattress and ensure its durability.




Orthopedic
The orthopedic mattresses used to be wooden and stiff. However, today, one of the best mattresses for back problems is the Orthopedic Premium Mattress, by Ortobom. It is a technological evolution of the classic orthopedic wooden mattresses, with Ecobambu fabric composed of fibers extracted from bamboo. This gives greater strength and helps not to retain heat. It is also a firm mattress and has a comfort foam layer that slightly follows the body's curvatures.
