Sleep is important in our lives. A properly organized sleeping place helps to relax normally. Well, if you have a quality double bed with a mattress. And it has an orthopedic effect. If you are out of luck with the bed, this can be fixed with a correctly selected mattress.
How to choose double mattresses
First you need to decide on the size.
Usually a mattress is bought for a particular bed. At the same time, in her documents, among other characteristics, the dimensions of the berth are indicated. If the bed was bought long ago and information about it was not preserved, then you need to measure the parameters yourself.
A common mistake is to take into account the external dimensions of the bed. In this case, the mattress will be more than a berth and will quickly deform. If you take much smaller, then he will ride on the bed, which is also not enough good.
The obtained measurement results may not correspond to the standard dimensions of the produced mattresses. In this case, you need to take the product a couple of centimeters less than your berth.
What products are called "double mattress"? Its dimensions are 140 × 200 cm, 160 × 200 cm, 180 × 200 cm and even 200 × 200 cm. Of these, the most common is 160 × 200 cm.
Mattresses are also available with a length of 190 cm, sometimes 195 cm. If your bed is smaller or larger than a standard double bed or you have purchased an original bed, for example, a round one, then you can order the double mattress you need, the size of which will suit your bed. To do this, you will have to pay an additional 10% of its cost.
In order to make it comfortable to sleep on the mattress, it must exceed your height by at least 15 cm. The more the person’s weight, the thicker the mattress he needs.
Height, or thickness, depends on the type of mattress. It can vary from 2 to 50 cm. The thinnest (from 2 to 10 cm) are used as a mattress for a sofa. The standard height of the product without springs is 16 cm, spring - 20-22 cm. Double mattresses of an elite class have a thickness of about 50 cm. But any of them should be higher than the king (sides) of the bed.
Orthopedic mattress
A more correct name is a mattress with orthopedic effect. Now he is on everyone’s ears. Such a mattress allows you to keep the spine during sleep in a natural position. That is, it does not bend either during sleep on its side or on its back.
At the same time, the mattress is not hard and does not cause discomfort. However, it is not suitable for everyone. For some diseases, doctors recommend sleeping on a hard bed. But for the prevention of these diseases, your family double orthopedic mattresses will be very useful.
Determination of the maximum load on a berth
Sometimes, after a few months of use, a new mattress loses its shape, and troughs appear on it. This can happen due to the fact that the load on the berth was not chosen correctly. It is indicated in the characteristics of the mattress and indicates what maximum weight the user can have. In the case when double mattresses are used, the weight of each of the users (not their sum!) Must not exceed the specified value. The numerical values of this parameter can be 90 kg, 100 kg, 105 kg, 110 kg, 120 kg.
Mattress stiffness
She may be:
- high;
- above average;
- medium;
- low
- variable (mattresses that can be turned over).
This parameter depends on the filler and the maximum load on the berth.
Mattress classification
Spring ones differ in block type and filler. Depending on the type of block, mattresses are:
- on an independent spring unit (new type);
- on the dependent spring Bonnel (old type).
Mattresses on an independent spring unit
Each of the springs is not connected to an adjacent metal connection. Under the influence of a person’s body weight, it bends. The cover does not allow her to lean to the side. Each of the springs bends depending on the load specifically on it.
The main types of independent spring blocks:
- TFK and S500 blocks. Each of the springs is in a separate case and acts independently of the others, changing its height according to the load. And the springs are about 250 per square meter, or up to 512 for one berth . Each height is more than 10 cm, diameter is about 6 cm. As a result, the mattress is adjusted to the configuration of the human body, therefore sleeping on it is convenient and useful. But the springs themselves will not create comfortable conditions for sleep. Typically, TPA is insulated with a thermal sheet and enveloped on both sides with a layer of ecofoam. As a substitute for latex, it gives the mattress softness and elasticity. The quilted cover is durable, a double mattress in it retains its shape and appearance.
- The Bee Honeycomb and Vemestet blocks have 350 springs with a diameter of 6 cm per square meter. They are staggered. Because of this, the mattress is more rigid.
- Block S1000 allows you to create an excellent double mattress, the price of which corresponds to its quality. It has about 500 springs per square meter. Diameter of each 4 cm. Designed for increased loads.
- The S2000 block has 1000 springs with a diameter of 2.5 cm per square meter. It has excellent orthopedic properties. Very expensive.
- Double Spring, Dual Spring - "spring in the spring." Double mattresses, created on the basis of such a block, are designed for people of various weight categories. Only after the external spring is pushed through the internal spring is activated. Users of such a mattress receive double support. There are 250 internal and external springs per m 2 .
- Reinforced - springs reinforced with thick wire. The thickness of the springs on only one side can be increased. Then a double bed with a mattress is divided into two zones, designed for people with different weights.
- The multizone spring block has springs of varying degrees of stiffness, divided into zones, which can be 3, 5 or 7. The stiffness of the head zone in such mattresses differs from the zone for the buttocks.
Mattresses on the dependent Bonnel spring block
They are quite reliable. They have 120-160 four-coil springs per square meter. These double mattresses are cheap. But the orthopedic effect is weak, because the springs are interconnected and are compressed under the influence of neighboring ones. The spring unit can last up to 15 years. The filler loses its shape faster. Now this design is considered obsolete. During use, under heavy loads, the springs begin to creak, can “shoot” and break through the mattress.
Positive characteristics of spring mattresses
- have a high orthopedic effect;
- withstand heavy loads;
- resistant to deformation;
- soft filler lasts longer in an independent spring unit.
Spring mattresses: what else needs to be paid attention to?
- Dust accumulates inside the unit. Dust may also be deposited on the face of the mattress, causing skin reactions.
- Static stress caused by metal parts of the structure can cause fatigue instead of resting during sleep.
- Moisture is poorly removed from the mattress frame, so the springs rust and creak.
- Fluctuations in movement are felt throughout the mattress.
- Sleepers do not have their own individual place and roll onto each other.
- The edge of the mattress reinforced with polyurethane or a metal bar can be very soft or too hard. Therefore, sitting and lying on the edge is inconvenient.
- The high price of quality products.
Springless mattresses
Such models along with spring ones have a good orthopedic effect. May consist of natural and artificial fillers. There are monolithic or puff.
Benefits:
- In their manufacture do not use metal components. Therefore, such mattresses do not create a magnetic field around themselves.
- They are lighter than spring ones.
- Do not accumulate dust.
- Moisture is removed from the inside of the mattress.
- Do not create the unpleasant sensations that are inherent in spring mattresses.
- Do not transmit vibrations from movement in a dream.
- Each of the sleeping has its own individual place.
- Comfortable position over the entire area of the mattress
- Recommended for teens and children.
- They serve longer than spring ones.
Disadvantages:
- Quality hypoallergenic fillers are very expensive.
- Stiffer spring.
Mattresses for full
Such products must be made of independent spring blocks (300-600 springs per square meter) and have high rigidity.
Can be taken with latex blocks and coconut coir floorings. They are not only reliable, but because of their elasticity they are not deformed and quickly acquire their original shape after use. In addition, they do not cause allergies.
Spring Mattress Fillers
In order for the product to be soft and comfortable, it is not enough to supply it with the right amount of spring blocks. First, they are covered with a lining of furniture mesh or felt. Then on both sides are covered with fillers, which give softness to the mattress. The thicker the filler layer, the more comfortable the mattress.
Fillers for soft mattresses:
- natural latex - contains at least 20% rubber, in elite this percentage reaches 85;
- polyurethane foam (foam rubber) - is an inexpensive analogue of latex;
- material with a memory effect, a special type of foam, slowly recovering from compression.
Fillers for mattresses of medium hardness:
- hollofiber (dense artificial non-woven material), struttofiber (may have additives from natural fibers) - more reliable than foam rubber;
- coir is a fiber that is obtained from coconut fruits. Usually diluted in half with latex;
- foam rubber with coir;
- coir and natural latex.
Fillers for hard mattresses:
- foam rubber and coir;
- coir and holofiber or stratofiber;
- coir (the most common).
Filler Location:
- On both sides. Allows you to turn the mattress from time to time. So it keeps its shape longer.
- One side. These can be both cheap options and the most expensive ones that do not need to be turned over.
- A different type of filler makes it possible to produce mattresses of variable (bilateral) stiffness. The soft side can be used in winter, the hard side in summer.
Sometimes manufacturers of mattresses use cheapened fillers. And there is nothing to worry about. If you want to save money and buy cheap double beds with a mattress, this is your right. But sometimes the manufacturer hides the presence of a cheaper filler in the product.
This happens if:
- foam rubber with a layer of less than 2 cm;
- latex is thinner than 3 cm;
- material with a memory effect of up to 3-4 cm;
- hollofiber (struttofiber) is thinner than 3 cm;
- coir in a mattress of medium hardness less than 1 cm, hard - up to 3 cm.
Using this information, you can understand why one of the two mattresses is cheaper.
Modern clamshells
Double mattresses can be used on folding beds. It is very convenient in the country or in a city apartment, where there is no extra space for extra beds, and guests are often. In such cases, a double cot with a mattress will solve many problems. After all, these are not those products that, when first used, turn into a hammock. More than a dozen lamellas (connecting strips) support the sleeping person and evenly distribute his weight. A high-quality orthopedic mattress with a height of at least 10 cm, equipped with a latch, allows you to remove the load from the spine and ensures a healthy sleep. Naturally, the mattress on the cot is not installed elite class. But such a design can easily withstand weight up to 250 kg, it can fit two even quite large people. Special wheels make it possible to transport it from place to place.
Cheap double beds with a mattress can be durable and of high quality. The secret is usually that the manufacturer uses domestic materials. A wide selection of models of mattresses allows you to choose the product that is most suitable for the price and quality of each customer.
