Sofas with a “eurobook” mechanism and a spring unit are among the most popular products among customers. Such furniture has many advantages, it is useful for human health and can replace a standard bed. However, you need to understand the differences between species, to know the pros and cons of designs, as well as the nuances of choice.
Advantages and disadvantages
Sofas with a spring block and a Eurobook mechanism highlight the following advantages:
- aesthetic appeal;
- folded compactness;
- variability of color schemes;
- variety of size range;
- distinction of design decisions;
- Availability for a wide range of customers.
This furniture is characterized by a smooth movement of the transformation mechanism. It is simple and silent in operation, reliable and durable. In the process of transformation, the sofa turns into a comfortable bed for one or two people. In this case, the type of construction may be different.
Sofas of this type are often equipped with internal storage systems. Under their seat there are capacious boxes for bedding or other things necessary in everyday life. The number of compartments can be different, as well as the depth of the boxes themselves. Besides, this furniture can be used as a guest bed or a regular sofa.
Products of this kind can be installed in rooms for various purposes. They are able to decorate the interior of living rooms, bedrooms, spacious kitchens. As well as sofas with the Eurobook system, they can become a key element of furniture in open-plan rooms. With their help, they divide the space of rooms into zones, introducing an unobtrusive organization into them.
But this furniture has several drawbacks.For example, such sofas cannot be placed close to the wall if you plan to use them constantly both as a sofa and as a bed. In addition, the constant transformation (unfolding and assembly) over time loosens the structural elements.
If the sofa is made from cheap raw materials, its life will most likely not be too long.
It is also bad that when unfolded, the berth has a longitudinal depression between the two blocks of the berth. The difference from the "book" mechanism is the principle of discovery. In this case, you do not have to fold the blocks, but raise one of them. The child will not cope with such work. In general, the walking mechanism is quite durable, it rarely breaks.
Varieties of spring blocks
Now there are 2 types of spring blocks that are used in the manufacture of upholstered furniture. Each of them has its own characteristics, which affects the operational characteristics of the products.
Dependent
The spring unit of the dependent type is not orthopedic, as it has a structure in which the springs are interconnected. Therefore, with a weight load, not only the working springs are pressed, but also most of the others. The human spine bends in an unnatural form.
The arrangement of the elements is vertical; they may vary in size and shape. On sale you can find options for regular and biconus type. The second types of springs are used to lighten the weight of structures and reduce the cost of metal elements. Such springs are less likely to break and overload under weight load.
The berth on the dependent springs may be different, but there is little benefit from rest on it. A person falls into a hole, a large load is placed on the spine. Limits punching under the weight of the user only the base of the design. If such springs break, you have to change the whole block.
Independent
These springs have visual differences from the counterparts of the dependent type. Each of them is packed in a separate case from a special breathable textile. In blocks of this type, not springs, but covers are interconnected. Due to this, only those elements that are under load are included in the work.
Due to this feature manages to achieve proper spinal support. Such blocks do not form holes under the weight of users. The size and type of items may vary. On sale there are springs not only single, but also double type (additional smaller elements are inserted into the workers).
The autonomy of the springs is their weak point. They often fail, but allow the replacement of individual elements. No need to throw away the entire block, replacing a broken spring is easy. The springs are standard, they can be bought in specialized stores.
Types of sofas
Classification of sofas with a Eurobook mechanism and a spring unit can be done according to several criteria. By type of stiffness, they are soft, moderately stiff and stiff. Products of the first type are not orthopedic. These are sofas with dependent blocks consisting of large springs.
Moderate rigidity already implies the presence of an orthopedic effect. The number of such springs per 1 square. m more than soft. In hard sofas, the number of springs is even more increased. The more springs and their smaller size, the stiffer the product. Double type springs are the most reliable and durable. Sofas with such springs withstand heavy loads.
By type of execution, factory structures having a metal frame are straight and angular. Linear models are bought for arranging rooms of a small area. Corners are purchased for living rooms and other open premises. The sizes of a berth of sofas are on sale the most different: 140x200, 200x160, 180x200 cm.
By type of transformation, there are models ordinary, as well as with rollback. The designs of the latter are distinguished by the presence of the back wall in the unfolded form of the sofa. They are convenient in that they do not need to be moved during the transformation.
By modification, sofas are divided into options with hidden and visible supports. The presence of legs makes it easier to clean under the sofa. Such furniture is easier to move from place to place. By the presence of other elements, sofas are with and without armrests. In some embodiments, the role of the armrests is played by soft pillows that are placed on the sides of the seats.
How to choose?
When buying, it is important to inspect the materials of the frame and upholstery of the selected model. Ideally, you need to take the option of a sofa on a metal frame. If this is not on sale, it is better to buy furniture with a wooden base. MDF and chipboard are short-lived, as they are not designed for heavy weight and everyday folding. The best upholstery material is considered to be genuine or artificial leather. Models with upholstery from chenille and flock proved to be quite good.
In addition, you should verify the reliability of the spring unit in connection with the purpose of the product. If you need, for example, a guest sofa that will not be used daily, you can purchase the product on dependent springs. Wherein stiffness should not be less than average.
If you choose the option for sleep, it is worth taking a closer look at models with independent springs. At the same time, it is better to take a product with a combined type of block. In fact, it is a mat with various types of springs, distributed in a certain way on the basis of the block. The number of springs per 1 square. m are selected based on their own health and age.
Elderly and sick are not recommended to buy options for increased rigidity. Although they withstand a heavy load, they are not suitable for all buyers. To take your option, you need to have an idea of which model is allowed for health reasons. The best option is a product with moderate rigidity.
When buying, you need to evaluate the comfort of the seat. Creaking, rolling, sinking does not speak in favor of the goods. The color of the model is selected for the background solution of the interior of a particular room. The sofa should stand out against the general background, but not get out of the general design concept. Its design, colors, decor are selected taking into account the style of the interior.
