Comparison Latona Prime Spice Lavr 70x190 vs Latona Prime Spice Chilli 70x190

— 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.

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).

Overall height (thickness) of the mattress.

This parameter is selected by the manufacturer, taking into account the general purpose and design features of the product, so in most cases it is not fundamental when choosing. We only note that traditional type mattresses have a thickness of 10 – 15 cm to 30 cm or more. And products with a thickness of less than 10 cm belong to the category of so-called futons, or toppers. Most often, such models are not used separately, but as additional overlays on another sleeping surface. For example, you can add a topper to an existing classic mattress — if it is not soft or hard enough, or if its properties have deteriorated due to wear — or lay the topper on a sofa, making the sleeping place on it more comfortable. Due to their thinness, futons are relatively inexpensive, and buying such a product is often more profitable than replacing an existing mattress.
