to judge the quality of a mattress, the most important thing is the spring system
all mattress spring systems are divided into three categories: wire drawing spring, round spring (independent chain spring) and independent bag spring. Experts said that generally, when buying mattresses, try not to choose wire drawing spring, because the noise of wire drawing spring is relatively large and the quality is poor. Generally, middle and high-end mattresses will not choose wire drawing spring
features of round spring: the whole mattress has an independent round spring, which is firmly worn together, making the whole mattress become one. The spring and the spring do not rub each other, there is no noise, can sleep safely. Independent round spring, integrated, balanced force, never deformation
characteristics of independent bagged spring: some people must be confused, what is independent bagged spring? In short, after each independent spring is pressed, it is filled with non-woven bags, connected and arranged, and then glued together to form a bed net. Because each spring body of the independent bag spring mattress operates independently, supports independently, and can stretch and contract independently, one of the two people lying on it will turn over or leave, and the other will not be affected at all, which can ensure a stable and comfortable sleep
each independent spring is loaded into a non-woven fabric bag and spliced into a bed net, which is stressed independently and does not interfere with each other. When a spring is pressed,
the surrounding area is not affected at all, so the mattress has better fit.
now the better mattress spring system on the market is round spring and independent bag spring. Independent bag spring is better than round spring:
1. The structure of independent bag spring is small on both sides and big in the middle, so it can be clearly seen that the springs do not rub each other ring extrusion, that is to say, it can achieve zero noise
2. Because of the independent telescopic function of the spring, the flat surface of the mattress is evenly stressed, and will not press the capillary of the human body, so as to avoid the feeling of pain and fatigue
3. More flexible than round spring, the mattress feels softer and more comfortable
experts say that there will be a phenomenon that round spring is pretended to be an independent bag spring in the market now. How can we identify two kinds of spring mattresses when we buy them
it's very simple. Touch it with your hand
when buying a mattress, consumers can touch the mattress spring system from the side. The independent bag spring is olive shaped, small at both ends and big in the middle; On the contrary, the round spring is large at both ends and small in the middle, which is concave. So when these two kinds of springs form a plane, we touch them with our hands. If we feel that they have been pushed in a few centimeters, and there is a feeling of steel wire, it is a round spring
there is also a kind of tricky business, which may make the outermost layer into independent bag spring, with round spring inside, so that the owners can not distinguish by "side touch". At this time, you can click the mattress. If you press down in one place, the perimeter is not affected, it is the "non-interference" independent bag spring
first look and then touch to simply identify the fabric of a good mattress
the mattress fabrics in the market are basically the same. Now the market has knitted fabrics, patchwork knitted fabrics, woven fabrics, woven fabrics, printed fabrics and so on. In general, the high-end mattresses are woven fabric, patchwork knitted fabric and knitted fabric
there are two aspects to distinguish a good mattress from the fabric: one is the gram weight, and the other is the wear resistance
the gram weight of mattress fabric, that is, the quality per unit area, is an important index to assess the quality of mattress fabric, and the non conformity of gram weight of fabric will affect the service life of mattress
how to see the gram weight of fabric? Look before you touch
for mattress fabric with high gram weight, we can clearly see that the density of knitted fabric is very high, and the gap between lines is small. It feels thick, smooth and delicate. If you press it hard, you can obviously feel the resilience, and there is no sound. And the wear resistance of the mattress, experts say, this is not hand can touch out, but by the professional machine detection. A good mattress can last up to 15 years. At first glance, small gap, high density, second touch, smooth hand feel, thick fabric
high-quality fillers determine the service life of the mattress and the direct feeling of consumers
besides the fabric and spring, the filling accessories are also very important for a mattress. With the development of emerging materials in the market, there are more and more patterns of mattress accessories. It is easy to fish in troubled waters, cut corners and save costs on this layer. Choose mattress, also cannot ignore this one close
at present, the filling materials of mattress mainly include cotton, sponge, memory cotton, brown and natural latex. Experts introced more latex mattresses, memory sponge mattresses and palm mattresses in the market
1. Latex mattresses:
according to the experiment, the number of bacteria and mites in the same environment of the five kinds of materials, only the latex mattresses, compared with other types of mattresses, have the most obvious bactericidal and acaricidal effect
the latex mattress made of latex has high elasticity, which can meet the needs of different weight groups, and its good support can adapt to various sleeping positions of sleepers. The contact area of latex mattress is much higher than that of ordinary mattress, which can evenly disperse the bearing capacity of human body weight, has the function of correcting bad sleeping posture, and has the effect of sterilization. Latex mattress another major feature is no noise, no vibration, effectively improve the quality of sleep
2. Super memory sponge mattress:
memory sponge, also known as space cotton, is simply a sponge that slowly rebounds. It was originally designed by NASA to rece the huge gravitational pressure on astronauts ring space flight. Memory sponge is composed of spherical cells, which has the function of pressure sensing and temperature sensing memory. It can react according to human body shape, weight and body temperature. The memory sponge with fine structure can rece the gravity pressure on the neck, spine and buttocks by 87%
e to the ability to absorb stress, memory sponge can significantly rece 80% of the times of turning over ring sleep, which will improve the quality of sleep. If some middle-aged and elderly friends have spinal deformation, the mattress can help correct the spine (cervical spine, thoracic spine, lumbar spine, etc.) to make it in a natural position, and avoid the deterioration of spinal deformation. In medicine, it is also concive to recing body pain, and can be applied to postoperative rehabilitation. Its air permeability can also help to avoid the occurrence of bedsore. 3、 Palm mattresses:
palm mattresses can be said to be the hardest of all kinds of mattresses. The most suitable groups are children and the elderly, people with poor spine, and people who like hard mattresses. Palm mattress has the advantages of good air permeability, natural materials, non-toxic and harmless to human body, all brown mattress adopts porous structure, which is more concive to air circulation and exchange
however, most of the traditional palm mattresses on the market need to be glued, so it is inevitable that there will be resial formaldehyde. Moreover, the formaldehyde in the glue is difficult to volatilize and clean, which generally takes more than 3 years to volatilize. Moreover, with the growth of the market, the glue coconut palm will be aging, which will lead to the degumming of the glue and the collapse and fracture of the coconut palm. So on the market at present, coconut palm glued with glue technology is not environmentally friendly. Mattress quality, not only professionals, we ordinary owners can distinguish. Mainly through three steps:
touch: good fabric features: smooth handle, thick fabric, tight gap
second sitting: good mattress features: the height is just level with the knee, the resilience of sitting down is large, and the texture is soft and comfortable
three lying: good mattress features: high fit with legs, hips, back and neck.
