Spring or springless mattress. Which one is better to choose?

What types of spring blocks are there?

Not all mattresses are created equal inside. Some have connected springs, some do not. Let's look at what a Bonnell spring block is, how springs are laid in a mattress, and what are the advantages of dependent and independent springs.

Bonnell spring block

Bonnell box springs are the most widely used option in the world for mattresses and beds. Frames undergo heat treatment processes to prevent sagging.

It is possible to produce wire with a width of 1.90 to 2.50 mm and a spiral with 4-5-6 turns for various height characteristics.

Customers often ask: What is the difference between a Bonnell spring mattress and regular mattresses? The answer is simple - reliability, durability, aesthetics and low noise level.

Independent spring block

It is believed to have been invented by James Marshall in Canada in 1899. This type of box spring only became popular in the 1970s when manufacturers found a way to mass produce the box spring style. Before this, several prototypes were made by hand.

Independent units are a great, inexpensive choice, while dependent units are a more premium option.

Individual coils of wire were hidden in pockets of fabric, which allow the coils to move independently of each other and follow the shape of the sleeper's body. Experts agree that these options provide unmatched support and comfort compared to any other type.

The softer box spring design can also be comfortable enough to sleep on long after the foam has lost its bounce, so you can sleep on this mattress for much longer before it needs to be replaced.

Most good quality independent spring designs will have at least 600 individual pockets in an XXL (king size) unit, which is more than enough to provide proper support and meet all standards.

Advantages and disadvantages

Many people believe that the dependent spring unit has long been outdated and is no good. This is a marketing myth. The truth is not so clear. The bonnel has its pros and cons, and they need to be taken into account when purchasing.

Advantages of bonnell spring modules:

1. Low cost compared to independent type modules. Bonnell is often used by manufacturers of budget furniture. But you need to understand that the dependent block also comes in different prices and quality.
2. Sustainability. Due to the fact that all springs are connected to the frame, displacement is eliminated. Accordingly, the sofa seat does not sag and holds its shape better. If we are talking about a frame mattress, it does not wobble, which is important for people with light sleepers.
3. High degree of reliability. On average, a Bonnell spring unit lasts about 15 years, but in practice there are cases where sofas and mattresses have not failed for more than 20 years. A long service life is ensured by the use of high-quality steel, and the fact that all elements are interconnected eliminates the displacement of individual springs.
4. Elasticity. Bicone spirals connected into a block do not sag completely even under increased load. Therefore, the mattress absorbs perfectly.
5. Hygiene. The spring block inside is almost hollow, thanks to this, normal air exchange and ventilation are maintained. And this, in turn, reduces the likelihood of mold and pathogenic bacteria appearing in mattresses and sofas.
6. Strength. Mattresses and sofas with a bonnel module are an excellent choice for children's rooms. Such upholstered furniture is quite capable of withstanding jumping and other children's pranks.

Despite the fact that the bonnell block has significant advantages, it is not without its disadvantages. You should find out about them in advance so as not to be disappointed after the purchase.

Cons of the bonnel module:

1. The main disadvantage of the design is the so-called “hammock effect”. The maximum deflection is formed in the tailbone area, and the head and legs are slightly raised. The more springs and the better the non-woven layer above them, the less this effect is felt.
2. The second significant disadvantage is that if two people are resting on a mattress, then the movements of one will also be felt by the second. This is the most significant and fatal drawback of the Bonnel and any other classic spring blocks.
3. Inexpensive varieties of mattresses with a bonnel block are not equipped with polyurethane plugs. Therefore, over time, the fastenings begin to creak. To extend the life of an inexpensive mattress, it is recommended to turn it over once every 3 months.

Production technology

Bonnell spring mattress - what is it? It is one of the earliest types of technology on the market. Bonnell designs are described as coupled coil technology. This type of mattress tends to be firmer due to its internal structure.

Because the coils are interconnected, this type of system tends to be more sensitive to movement. This means that when someone moves on one side of the bed, the person on the other end of the bed can also feel the movement.

However, Bonnell mattresses tend to be durable and affordable for many (due to their low price).

Main characteristics of the Bonnell spring block

King size mattresses most often use Bonnell technology. Manufacturers also use them in “commercial grade” mattresses based on the belief that Bonnell springs are longer lasting than standard springs.

The Bonnell design consists of many hourglass-shaped coils, all connected together by rows of metal spirals (these are the long wire corkscrews that pass through the top of each spiral when they are inserted through the top of the block).

The entire block is then surrounded by frames at the top and bottom of the block (around the perimeter). Most XXL size Bonnell blocks contain approximately 360 threads, but of course they can be made with fewer or more depending on thread size and/or quality.

Features of fillers in mattresses with a dependent block

In such mattresses, vibration is weakly felt; the body does not fall down, but remains on the surface, although the muscles are relaxed enough for the body to rest. Even during long periods of sleep, the bed does not put much pressure on the skin and does not press marks on it.

The disadvantage of this design is that if one spiral breaks, you will have to go through all the insides to restore the elastic properties and distribute the elasticity of the mattress evenly over the entire surface.

The Bonnell spring block is becoming more popular every year.

Comparison with a block of independent springs

A more modern option for the internal filling of sofas and mattresses are blocks with independent springs. The difference is that the elements are not connected to each other, each of them is located in a separate case.

With this design, under load, only those springs that are affected are compressed, the rest remain in an unchanged position. In blocks of this type, springs of a smaller diameter are used, that is, there are more springs per square meter. This provides a greater degree of elasticity and density. There can be from 265 to 1000 springs per square meter. The best option is considered to be samples with 350-400 elements per square meter.

Tips for choosing a mattress

Pay attention to these factors:

• The main difference between spring types is that instead of having a round top, the spring usually has a hexagonal shape, which allows the coils to pack closer together.
• Manufacturers claim that this also allows the individual coils to fit more easily into the housing, but the fact that each coil is tied together makes the claim questionable.
• The individual coils in the LFK unit do not have knots at the top of each spring like Bonnell coils, which also affects performance and comfort.

LFK coil units typically contain many more springs than traditional Bonnells, making them stronger.

However, this statement remains questionable because the frame itself can also wear out.

Comfort while sleeping on springless and spring mattresses

In spring and springless mattresses, this function is responsible for:

• mattress top layer fillers;
• fabrics and materials stitches of the cover;
• various types of impregnation.

Comfortable layer of springless and spring mattresses

Accordingly, there are no fundamental differences in this aspect between spring or springless mattresses.
The only thing is that in a spring mattress, pay attention to the thickness of the comfort layer; if it is very thin (no more than 2-3 cm), you can feel the springs. If you like elastic-hard surfaces, choose mattresses containing coconut coir, sisal, horsehair or flax. The only thing, remember that no matter what the block in the spring mattress is, the thicker the layer of hard filler, the less the anatomical operation of independent springs is felt.

If you like elastic-soft mattresses, choose natural latex, polyurethane foam and memory foam as the top layer.

Covers for springless and spring mattresses

A pleasant microclimate on the surface of the mattress will be created by covers made of natural fabrics: cotton, bamboo, Tencel. Additional comfort is provided by various treatments and impregnations:

• antibacterial;
• antistatic;
• antiseptic;
• fire protection;
• mixed.

Properties of a spring mattress

Let's consider what is good about this or that spring option.

Advantages

Independent mattresses, unlike Bonnell ones, distribute each coil separately. This spring system design reduces movement when one person moves at one end, reducing interruptions during sleep.

This factor is especially relevant for consumers who are looking for a king-size bed or larger.

The spring systems also provide ample support throughout the body. However, individual pocket coils respond differently to different pressure points and body weight. Mattresses with this type of coil technology are softer than Bonnell.

Flaws

Springs can jump out of the mattress, get tangled, crack, move to one side, or lose tone. For prevention, you need to take the mattress for diagnostics and replacement once a year.

Another disadvantage is the weight. Such mattresses are much heavier than more advanced designs.

Effective support in spring and springless mattresses

For the most part, the spring block, the supporting structure, is responsible for providing proper support (orthopedic effect) in a spring mattress.
Unlike spring mattresses, in springless mattresses only fillers are responsible for high-quality support. The main difference between spring and springless mattresses is that any springs create a springing effect, that is, slight vibrations when you sit down, lie down or roll over. Unlike spring mattresses, in springless mattresses any vibrations are damped immediately, since the fillers have low springing properties. When choosing between buying a spring or springless mattress, usually everyone decides for himself whether he likes the springy properties of mattresses with springs or the calm surface of springless mattresses. If this does not matter to you, you will have to choose a mattress based on other parameters.

Spring mattress support

The Bonnell spring unit has the lowest level.
This is due to the fact that all the springs in it are intertwined with each other and the load on one spring also activates the neighboring ones (wave effect, hammock effect). The created surface little corresponds to the anatomical features of the human physique, making it difficult to completely relax. Therefore, if possible, it is better to prefer other options. The best mattresses in terms of proper support are mattresses with an independent spring block. In them, each spring reacts only to its share of the load, and the entire block follows the contours of the sleeper. Moreover, the higher the spring density per 1 sq.m., the higher the orthopedic and anatomical effect, and the mattress itself can withstand more weight.

Support for springless mattresses

Unlike spring mattresses, only fillers are responsible for high-quality support in springless mattresses.
The harder the filler, the lower the anatomy of the mattress, and the higher the orthopedic support and vice versa. Therefore, the comfort of hard mattresses is very individual, and hard springless mattresses are recommended for purchase on the individual advice of orthopedic and somnologist specialists. Springless mattresses of medium hardness are monolithic high-density foams or alternating hard and soft fillers. The level of orthopedic effect in such mattresses is also average.

Mattresses made from natural latex, including zoned ones, have the highest anatomical properties, but their main drawback is their high price. Manufacturers of mattress fillers are constantly working on developing various foams that would be as close as possible to natural latex in properties, but at the same time cost much less. Such foams, as a rule, have a patented trade name: Ergolatex, Ergofoam, Ortofoam, Ormafoam, etc.

Types of mattresses with spring blocks

There are quite a few different types of box springs used in mattresses. And they all have their pros and cons.

Generally considered the traditional option by most manufacturers and experts, the best type for comfort and fit. And is usually used in premium style and more expensive models.

All Sherman mattresses (the world's leading manufacturer) use this type of coil. The rest are just variations and modifications.

Types of mattresses without a spring block

Bed mattresses, whether with or without springs, have several modifications. For example, “winter-summer” types are in great demand, where on the one hand the filler is a thermal insulation material that retains heat in the cold season, and on the other hand there is a breathable, environmentally friendly filler that creates comfortable conditions in the heat. Another option is when fillers of varying degrees of hardness are placed on different sides.

What to choose: Bonnell block or independent springs

Each type has its pros and cons. Understanding the strengths and weaknesses of each helps you make informed, informed decisions about which is best.

It is important to note that the type of spring system is only one component. Other important factors such as coil thickness, number of coils, and even the type of foam used in conjunction with these spring systems can affect the overall strength.

Independent springs can be found in all old beds. Many generations have felt what it’s like to sleep on them.

Advantages of Bonnell spring mattresses

The main advantage of Bonnell is its light weight and ease of delivery/installation. These mattresses perfectly support your sleeping position and allow you to relax and unwind.

Another advantage will be the manufacturer’s warranty - more than 5 years. This means that during this time the mattress will not sag and will maintain its elastic properties.

Advantages of mattresses with independent springs

This includes time-tested reliability and low price. In order to get a sufficient level of comfort, you don’t have to invent anything. Everything has already been tested and approved many generations ago.

Which mattress is suitable for whom?

Springless mattress, bonnel, independent spring block, having studied their pros and cons, you can determine which mattress is best for whom:

1. It is better not to skimp on children and, between the ages of one and 12 years, equip the baby’s sleeping place with a natural latex mattress. It will not create unnecessary swaying, will not spoil the developing posture with excessive rigidity, and will not provoke an allergic reaction. It is important to consult with a pediatric orthopedist before purchasing a mattress in order to properly distribute the load.

   Natural latex mattress

2. An adult who does not have health problems can choose a mattress to suit his taste, based only on his taste preferences and financial capabilities. If there is a history of cardiovascular pathologies, problems with the respiratory tract, spring structures should be excluded. A similar decision will be correct for body weights over 100 kg.
3. Problems with the spine can make a coir mattress a contraindication. With such diseases, you cannot go shopping for a mattress without consulting a doctor; only a specialist can competently justify the need to purchase a spring block or a mattress without metal spirals in order to save the patient from muscle tension and new attacks.
4. Discomfort from a hard springless mattress is also the basis for choosing a classic model. You should not choose a bonnel; it is better to pay attention to independent spring blocks. The more curls in its cells, the better.
5. If you are on a limited budget, you should not try to buy a springless mattress. Made from artificial materials by questionable manufacturers, they can be toxic and cause allergic reactions and poisoning. In this case, a high-quality spring block will be better for your wallet and health.

Advice! Arrangement of a sleeping place is associated with significant expenses from the family budget. So that they are not in vain, before buying a mattress or sofa, you should not waste time consulting with an orthopedist. At the appointment, it is better to take extracts from the medical records of the family members for whom the future purchase is intended.

In matters of your own comfort, you should not chase fashion or advertising slogans. Each type of mattress has its own pros and cons, from which a specialist can create the optimal formula.
