The “snake” spring got its name due to its peculiar sinuous shape, reminiscent of the body of a snake when moving.
In most cases, it is used as a filler for sofas and chairs. Upholstered furniture made using snake springs has good orthopedic qualities.
Let's tell you more about popular springs. This will allow you to independently determine whether it is good or bad for you if there is a “snake” installed in the sofa.
What is a sofa spring and how does it work?
A metal frame that is attached to a wooden base and maintains the shape of the soft filler is the sofa springs. Depending on the type of mechanism, the elements may be connected to each other or not attached to each other.
In more expensive models, there is a layer of dense fabric (often felt) under and above the spring block. This prevents premature wear of the mechanism. In budget models, only the upper part is covered with fabric, and foam rubber is used as a filler.
The choice of foam rubber must be taken carefully and responsibly.
What to choose: Bonnell block or independent springs?
To decide on the type of spring block, you need to know what requirements a quality product must meet. The sleeping area must be of a suitable size, safe and hypoallergenic, hygienic and comfortable.
The main selection criterion is comfort, because... blocks differ in degree of rigidity. When choosing a sleeping place, you should take into account personal preferences, anatomical features and weight of a person, and price range. The bonnell block is more affordable, but has a less pronounced orthopedic effect due to the rigid bundle of springs.
Independent spring blocks are more anatomical, have different stiffnesses, and are suitable for people of different ages and builds.
Advantages of mattresses with bonnel spring block
The Bonnel system has a number of advantages:
- high reliability and durability due to the rigid frame and heat treatment of the wire;
- a special shape, thanks to which the coils of the spring do not rub against each other, do not creak, and can withstand a weight of more than 100 kg;
- affordable price;
- The Bonnel block has a hollow design, which ensures hygiene and air circulation, reducing the possibility of bacteria and insects.
Advantages of mattresses with independent springs
The independent spring block also has advantages:
- there is no hammock effect, because the spirals are packaged in separate cases and are compressed in the place where pressure is applied;
- smoother surface, partners with different weights do not interfere with each other’s sleep;
- the possibility of zoning the product depending on the anatomical features of the person;
- individual selection of the degree of rigidity;
- elasticity, elasticity, noiselessness.
If you have diseases of the spine or back, you should consult your doctor before purchasing.
Types and advantages of mechanisms
The methods of fastening and the location of the springs in the block depend on its type. Let's look at all the options for the mechanism, tell you what a spring snake is in a sofa, and how it differs from a multi-pack.
Choosing a quality sofa is not so easy.
Independent
One of the most reliable and modern blocks. Each spring is in an individual fabric case; the elements are not connected to each other. The mechanical load is distributed only over the springs involved: if there is no pressure on some area, it will not sag under the weight.
Independent springs are considered the best option in sofas for daily sleep.
Due to this feature, blocks with independent springs are considered the most reliable. If one spring fails, you do not have to repair the whole unit. The sofa will not sag and lose elasticity. Most often, sofas with independent blocks have small springs made of thin steel wire.
For springless filling, foam rubber or polyurethane is used.
Bonnell
This system uses double-cone springs, which consist of 4-5 turns. They are connected by a steel frame. The design is impressive and durable. Bonnel has several frames, due to which the rigidity of the base is achieved. This system is reliable and durable.
Dependent springs Bonnel (Bonnel) are an economical option for filling for upholstered furniture.
Bonnell systems are very popular due to their features:
- springs are made of high carbon steel, environmentally friendly;
- The block can be laid on a base made of any material, including plywood or MDF.
The production of Bonnell blocks is simple, so basic mattresses with them are inexpensive.
In corner sofas, the sides are lined with polyurethane foam boxes, and the top is covered with batting or felt. Used for sofas with various folding mechanisms, found in accordions and books. The service life is several years, but with careful use it can last longer.
Multi-package
In appearance and manufacturing pattern they resemble independent springs. Each item is also placed in an individual case. The difference between these blocks is the size of the springs. If in standard independent systems the elements are larger, then in a multi-package a large number of small springs are used.
Smaller springs respond more “sensitively” to pressure - they adapt very well to the user.
At the same time, sofas with such blocks are very durable and can withstand significant weight.
Advantages:
- weight is distributed evenly;
- the springs are not connected; if one fails, the system does not fail;
- due to the cover, the broken spring is not visible through the upholstery;
- have a supporting effect;
- Suitable for most models.
MicroPocket – for sleep, load up to 150 kg.
When purchasing a sofa with a multiblock, you need to pay attention to the number of springs. There must be at least 435 of them.
Snake
What does a snake spring look like in a sofa: the elements inside the frame are connected by steel brackets, they are interdependent and resemble a snake in appearance.
Spring snakes are familiar to us from Soviet furniture and in fact are not a block.
Such blocks are made from galvanized steel under high temperatures. The most reliable bases are those with a large number of bends.
Such a sofa “gives up” most quickly under the weight of the human body, is pressed deeply and begins to resemble a hammock.
The main advantage of the mechanism is that it is cheap. However, sofas with a spring snake are not suitable for upholstered furniture for frequent use.
This is the cheapest, but also the most creaky option.

What color to choose for the sofa?
All soft sofas on the information website of the Eris furniture salon can be made of any fabric, one of five categories. It should be remembered that the higher it is, the more expensive the selected product will cost. Fabric options are listed in the detailed product description. Fabrics are divided into five categories containing a large number of colors. We hope that you will make the right choice.
What is a reinforced and regular spring block?
The reinforced spring block differs from the usual one and has a more reliable design. The wire from which the springs are made is of special hardening and thickness. The metal (wire) is made specifically from spring steel, which means that the price is correspondingly more expensive than a regular spring block. What does this affect... for quality and service life, that is, with proper use, a regular sofa will last you 3-4 years, after which it will definitely wash out, and the reinforced spring block will not tear the fabric on the sofa
Classification of fabrics (which one is better to choose?)
Flock - This fabric has a velvety surface and consists of two layers (the top layer is synthetic, the bottom layer is cotton). Perfect for pet owners. Waterproof and dirt-resistant, washes well, and is also not susceptible to fading in the sun
Tapestry - This type of fabric consists of 60-80% cotton, and is considered the most natural upholstery fabric. This material requires dry cleaning.
Chenille - For the production of chenille, both natural and synthetic threads are used in various percentages, mainly viscose, cotton, acrylic, polyester. The technical characteristics of modern chenille - wear resistance, color fastness, strength - are quite high and significantly exceed the minimum acceptable requirements of the standards. Important: avoid direct sunlight, do not bleach, do not use strong abrasive cleaning agents, do not use petroleum-based solvents. NOTE: Shinil has a complex composition and is highly wear-resistant due to its density and strength. The composition may include several threads of the same origin (polyester) or mixed (synthetic fiber with threads of acrylic, cotton, viscose, linen). The fabric has an optimal balance of consumer and environmental properties, providing stylish comfort and ease of care for furniture
Jacquard - This type of fabric consists of natural (to a greater extent) and synthetic fibers, it is often called rayon. It bears a relief design. Dry wash recommended.
Velor - This material consists of natural and synthetic fibers. There are two types (with long and short pile) The main disadvantage of this fabric is its low abrasion resistance
Artificial leather - Compared to natural leather, it has a low price. Has increased strength and high wear resistance
How to choose the right one
The first question that needs to be answered is how the furniture will be used. If this is a folding sofa for sleeping, you should pay attention to orthopedic options with independent blocks. Sleeping on them is much more comfortable, the body will feel rested.
Store managers will help you choose a sofa.
It is also important to choose the “right” filler. Foam sofas are not as reliable and durable. After a few years, it will begin to sag, and the springs may dig into people sitting or lying on the sofa. It is better to pay attention to coconut coir - it is tougher and more reliable than foam rubber.
The material of its production is high-carbon spring wire of different thicknesses.
For most, the cost of the product plays a significant role. Sofas with dependent spring blocks are the cheapest, but if you plan to use the product for a long time, you should not buy the cheapest models. It is better to pay attention to the average price category, since such sofas will last longer and will not require repairs after several months.
Prices for different springs may vary.
Advantages of the “snake” spring block
This type of block is one of the most popular for the production of sofas. Furniture with such filling has certain advantages.
- The spring is able to withstand heavy loads and maintain its shape even under the influence of large people.
- High levels of wear resistance and durability.
- Quiet in operation: high-quality products do not emit extraneous sounds or squeaks.
- Good level of ventilation. The spring block is capable of maintaining the temperature of the human body for a long time. It is this feature that helps him breathe and generally has a beneficial effect on his well-being.
- The sofa has a flat surface.
- Easy to transport and install.
- Price available to the buyer. Of course, the price range for furniture is wide. It depends on the materials used, the design features of the product, as well as the manufacturer and other factors. However, on average in the market, the cost of such sofas remains acceptable for most consumers.
This type of blocks gives the sofa a special softness and orthopedic effect. Therefore, the use of such furniture is recommended by doctors as a therapeutic agent.
Operating rules
In order for the spring block to last longer, you need to follow the basic rules for handling upholstered furniture:
- do not stand on the sofa with your feet, so as not to create a point load in one place;
- do not jump on it from a running start, so as not to damage the mechanism;
- carefully lay out and fold furniture to prevent deformation of the frame;
- If creaks appear or the sofa sag, immediately carry out repairs (on your own or call a specialist);
- When rearranging, do not drop or shake the sofa.
Careful handling of the sofa will increase its service life.
The more carefully the furniture is used, the longer it will serve its owners.
Fastening snake springs in a sofa
Installing springs is not particularly difficult, especially for experienced craftsmen.
REFERENCE! The spring is made of durable steel, which is bent under high temperatures.
Then it is coated with a special composition, thanks to which it does not corrode.
The springs are attached inside (or on) a metal or wooden frame. In this case, a certain distance between the fasteners in the transverse direction is maintained.
The fasteners themselves are curved and are used for greater reliability. Their number is determined by the size and shape of the furniture. The frame of the product is very stable and does not sway.
There must be a polyurethane foam layer between the snake and the frame. It prevents hard material from coming into contact with the upholstery.
IMPORTANT! Furniture with such a spring has good performance characteristics and can last at least 20 years.
Mounting features
Spring blocks are attached to a base made of plywood or MDF, covered with felt (for better grip). In some models, instead of sheet material, wooden or metal slats are used, which are attached to the yards. Foam rubber, padding polyester or other filler is attached on top of the spring block. It provides softness and comfort.
If necessary, the spring block can be replaced with an identical one. The “snake” system is not difficult to repair with your own hands using strong cords and fastening with thick wire staples. Typically, such mechanisms are repaired independently or with the help of a specialist.
You will receive not only a beautiful, but also the most comfortable model, which will become an island of relaxation in your home.
