Comparison Matroluxe Azalia 140x200 vs Velam Super Hit 140x200

— Springless. Filler only design without any springs. See below for more information on the different types of fillers. Also note here that the springless design has good orthopedic performance, is almost silent, is much less prone to uneven wear than the spring design, but handles worse with high loads and costs significantly more. It is considered optimal for children's mattresses (see "Purpose"), but is also widely used in "adults".

— Spring (independent blocks). Actually, the name itself describes a characteristic feature of these mattresses and their difference from the Bonnel systems: each spring in such a product is separated from the rest and compresses and decompresses independently. Due to this, a very high orthopedic effect is achieved: the mattress very accurately adjusts to the shape of the sleeping person's body, because. only springs under load sag. Note that the independent design has several varieties, which differ, in particular, in the number of springs per unit area. At the same time, the more springs are provided, the more comfortable the mattress will be, the better its orthopedic properties will be; however, the price also rises accordingly. Actually, the higher price is the main drawback of this design compared to the Bonnels. In addition, all mattresses with springs, regardless of type, have a number of common drawbacks: they tend to “squeeze through” and lose elasticity d...uring operation, and metal springs can be made from different materials, including not very resistant to corrosion.

— Spring (Twin Pocket). Models of independent spring mattresses made using double spring technology. Each manufacturer calls this technology differently: Twin Pocket, Dual Pocket, Dual Spring, etc. It consists in the presence of an additional reduced spring inside the main one. With a significant load on the mattress, it comes into action, reducing the impact on the main spring, which in turn prevents pushing through, which is the fault of independent spring mattresses.

— Spring (Bonnel). The simplest and most inexpensive type of construction, both among spring models and in general among orthopedic mattresses; It was used back in Soviet times, and is still found today. The springs in such a product usually have a characteristic hourglass shape (narrowed in the middle), and each of them is connected to two adjacent ones. "Bonnels" are quite reliable and can withstand heavy loads well, but they have one serious drawback: when you press on a separate spring, not only it is compressed, but also the neighboring ones associated with it (the so-called "hammock effect"). This significantly reduces the orthopedic properties, and also leads to the characteristic squeak of the springs. At the same time, this design is also characterized by all the main disadvantages of spring systems, described below in paragraph "Spring (independent blocks)". Therefore, it is usually used in inexpensive mattresses intended for people without serious health problems.

— Independent blocks / Bonnel. A type of mattress that combines the two types of spring blocks described above in its design. The ways of combining such blocks can be different. So, in one embodiment, an independent block is located closer to the top of the mattress and provides the necessary orthopedic properties, and the Bonnel block installed under it optimizes load distribution and increases the reliability of the structure. Such a mattress may have the properties of a two-sided model (see below) — spring blocks may vary in stiffness. Another option is double models, in which the beds have different types of spring blocks; it will be useful in the event that the requirements of partners for a sleeping place differ. However, both options have a rather high cost, and for the first — also significant weight and dimensions.

Rigidity is one of the most important characteristics when choosing any mattress. Modern models can be soft, medium or hard.

It is believed that products of any rigidity are suitable for healthy people, and the choice in this case depends solely on personal preferences. However, there are certain recommendations related to a person's weight and allowing you to determine which option is most likely to be the most convenient. So, for people weighing up to 60 kg, a soft mattress is considered optimal, 60-90 kg - medium, more than 90 kg - hard. This, however, applies only to "adult" models; Children's mattresses are standardly medium firm. If the mattress is selected for a person with spinal problems, it is advisable to consult a doctor before choosing.

Note that there is a separate category of mattresses that combine different hardness. Most often, these are two-sided models with different stiffness on each side - this allows you to change the stiffness by simply turning the mattress over (for more on the meaning of this function, see below). In addition, double versions with different side stiffness can be produced; see below for more details. All similar products in our catalog are labeled "soft/hard" or "soft/medium", depending on the combination.

In describing the rigidity of the model, we additionally ind...icate the rigidity in numbers (on a scale as is customary in the field of describing the rigidity of mattresses) from 1 - soft, to 5 - hard.

The number of individual layers of filler provided in the design of the mattress. By itself, this parameter does not have a special effect on the overall quality and practical features of the product - these moments are determined primarily by the filler materials (see below) and other design features. However, in spring mattresses (see "Type"), more layers usually correspond to a greater thickness of the filling - which means that the customer is less likely to feel individual springs on such a mattress.

Note that the cover is not taken into account when counting the layers - it is not always included in the kit, and, as a rule, can be replaced if necessary.

Now on the market there are mattresses with the following number of layers: 1, 2, 3, 4, 5, 6, 7 and more.

The material used to fill the interior space of a mattress. In spring models (see "Type of orthopedic"), this parameter plays a secondary role, because. stiffness, orthopedics and other important characteristics are determined primarily by the springs used. But for springless filler properties are extremely important, and the materials used should be paid special attention.

- Polyurethane foam(PPU). A fairly popular synthetic material that provides medium to high stiffness characteristics. It is produced in different variations, differing in density and, accordingly, durability and price (the denser the PPU, the more reliable it is, but also more expensive). The foam structure allows the use of vacuum packaging ; in addition, memory foam mattresses (also described below) are most often made from polyurethane foam with special additives. Pure polyurethane foam is in many ways similar to latex, however, on the one hand, it loses to it in softness and elasticity, on the other hand, it is considered more hypoallergenic and also costs less.

— Latex. Speaking of mattresses, latex most often means a natural variety of this material, based on wood rubber, with some synthetic additives. Like the PPU described above, latex has a foamy structure, it is more resilient, but also softer - the rigidity of such mattresses varies from...low to medium. Latex mattresses are considered very comfortable, because. provide natural tight support for the entire body; in addition, they are quite durable. On the other hand, the price of such products is higher than that of polyurethane foam, and the anti-allergic properties are somewhat worse (although latex is rightfully considered a hypoallergenic material).

- Coconut or cactus fiber. Also known as coconut coir or sisal (respectively). It is a natural fiber bonded with latex. Such mattresses are positioned as the most natural products, although the mentioned latex can also be synthetic. They are distinguished by a very high rigidity (although quite elastic), strong, durable and quite hygienic, because. when properly processed, the fiber does not accumulate odors and moisture. On the other hand, the cost of such mattresses is quite high, and under heavy weight, the material can crumble - so they are poorly suited for massive people.

- Spunbond. This material is a non-woven fabric of synthetic origin: during its production, molten synthetic material is drawn into threads, which, after solidification, are fastened together by temperature, adhesive or other means. As a result, the fabric is soft, but at the same time durable to tear and abrasion, safe for humans and at the same time inexpensive. Among mattresses, spunbond is found mainly in spring models (see "Type"). It is used as a "shield" to protect more delicate materials and upholstery from contact with the springs. At the same time, most products using spunbond have low rigidity - in more rigid mattresses it is more reasonable to use appropriate materials for the same purposes, such as coconut coir.

- Strutofiber, periotek, etc. A family of materials based on vertically arranged fibers - usually of natural origin, like wool or cotton, but there are also artificial ones. Such materials are notable for their low price and quite decent (though not outstanding) performance characteristics. Their rigidity varies from medium to high.

— Felt. Material based on dense felted wool. It has a very low wear resistance, which is why it is practically not used as an independent filler and usually plays the role of a small layer between thicker layers of other materials.

Note that modern mattress fillers can combine several options at once - for example, polyurethane and latex for double-sided soft-hard models (see "Two-sided"), or several alternating layers of coir and latex.

The maximum weight for which one bed of the mattress is designed is, in fact, the maximum weight of a person who can regularly sleep on a mattress for a long period of time without the risk of "overloading" and spoiling the product. Of course, this parameter cannot be exceeded; however, when purchasing a mattress, you should also make sure that the selected model has a certain weight reserve — at least 10 kg. This is due not only to the fact that the mattress can be used by different people (and the weight of permanent owners can also change), but also to the uneven load that occurs during use. The fact is that manufacturers can specify this parameter per sleeper, i.e. practically immobile person. In fact, the matter is not limited only to sleep — as a result, the mattress may experience a load greater than the calculated one, even in cases where the weight of the person on it does not exceed the claimed characteristics.

The number of springs per square metre of surface in a mattress of the appropriate design (see "Type"), in other words, the density of the springs. The greater this number, the higher the density of the springs — the smaller the size of each individual spring and the more accurately the deflection of the mattress will correspond to the contours of the body of a lying person (ceteris paribus, of course). On the other hand, the use of numerous springs significantly affects the price. Among the main spring blocks are Pocket Spring(~ 256 springs/m²), Multipocket(~ 512 springs/m²) and Micropocket(~ 1024 springs/m²).
