Many small partners choose mattresses and
When a man with a height of 175cm and a weight of 68kg is lying on a spring mattress, the middle section of the mattress supports about 40kg, and the two ends of the mattress only need to support about 17kg and 11kg respectively, which is a huge difference. If the middle section of the mattress cannot provide stronger support, it is easy to cause the middle part of the body to bend downward.
Zone mattresses are developed on the basis of independent springs. At present, there are three zones, five zones, and seven zones on the market. The partitioning principle is to achieve different mattresses by changing the wire diameter (the thickness of the spring steel wire), adjusting the compression ratio (increasing the height of the spring before bagging) and changing the number of turns (increasing the number of spring coils). Softness and support.
According to ergonomics, the seven zones are designed according to the force of the seven zones of the human body including the head, neck, shoulders, back, waist, buttocks, and legs. It can fit the curve of the human body and allow the spine to stretch healthily while sleeping.
Partition Design Basis Of Foam Mattress
Firmness is the core issue of mattress design. Let's talk about the "good" mattress first. The standard mattress is too hard and too soft to be comfortable, and it is easy to make people form bad sleeping positions. This sleeping position is unnatural.
The harder the bed core at the waist position, the smaller the contact area between the shoulders, back and buttocks and the mattress, and the more dispersed the force is, the greater the force on the waist is, the greater the pressure on each part will be. The harder the bed core at the shoulder and back position, the smaller the contact area between the buttocks and the mattress, the more concentrated the force, the greater the pressure, the smaller the pressure on the waist and the smaller the force. The harder the bed core at the buttocks, the larger the contact area between the shoulders and buttocks and the mattress, the more dispersed the force, the smaller the pressure, and the more concentrated the force on the waist, the greater the pressure.
Combining the above two design bases, it is generally believed that for people with leaner body types, mattresses with different overall firmness, softness of the bed core at the waist, and small gradients in the differences between the shoulders, back, and hips are generally considered suitable. Overweight people are suitable for partitioned mattresses with hard cores at the waist, medium-hard cores at the shoulders and back, soft cores at the buttocks, and a large gradient between the cores at the waist and buttocks. Generally, people with a standard body type are suitable for partitioned mattresses with soft bed cores for the shoulders, back and buttocks, and medium-hard bed cores for the waist.
In fact, the zoning design of mattresses is a concept of continuous development. In my opinion, the key to structurally partitioning mattresses is not the number of partitions, but how to consider the rationality of the partitions from an ergonomic point of view to make more detailed elastic settings for each domain.
