When buying a mattress , the different circumstances of each member should be considered as much as possible. Generally speaking, the length of the bed is preferably at least 15 cm longer than its height, so that it can be turned freely on the bed; as for the hardness of the mattress, it should be mainly comfortable. Specifically: children ’s mattresses are slightly harder and should not be too soft, so as not to affect the normal development of the spine. A small steel bed can be used. Be careful not to use the old steel bed left by others to avoid the deformation of the mattress and the center. Sagging; you can also use a small mattress with a wooden fence, covered with thick bedding to increase softness. The mattress of adolescents should be moderately soft and hard. Too hard or too soft will lead to spine dysplasia. When choosing, parents can use the palm of their hands to feel, no matter what kind of mattress is available, as long as the hardness is moderate. Adults should choose mattresses designed according to biomechanics, which can relieve fatigue and improve sleep. The elderly, especially those who are thin and chronically bedridden, should choose soft and moderate mattresses with good breathability to avoid localized bedsores. At present, mattresses are more popular in China. There are many kinds of cushion materials, including sponge, foam, horsehair, coconut hair, pure cotton and latex. Relatively speaking, the latex bed has strong elasticity and high softness. The recesses and voids on the mattress are designed according to ergonomic principles and are not easily deformed. This mattress is placed on the bed board and can play a role in maintaining the human physiological curve , Adults can choose. Some latex mattresses are made of pure natural materials, with better breathability, suitable for those with allergies. As for Simmons mattress products that use springs as fillers, because the springs are easily deformed and parts of the mattress are easy to collapse, it is best not to choose them for children. If the mattress is found to be poor in elasticity or partially collapsed, it should be replaced in time so as not to affect health. The traditional brown trampoline has good breathability, softness and elasticity, and is most suitable for the elderly. However, with the extension of use time, the braided brown rope will gradually relax, resulting in weakened elasticity. Therefore, those using brown trampoline should replace the brown rope after 3 to 5 years or according to the feeling to enhance the elasticity. A pure wooden bed is too hard, which is not conducive to the health of the spine. For example, it is an option to place soft bedding on it. At present, there are some expensive "alternative" mattresses on the market, such as air mattresses, sand beds, and water beds. Through the flow of gas, sand, and water, the negative focus of the human body is constantly adjusted. In general, such mattresses are more suitable for patients with special treatment requirements. They should be purchased under the guidance of a doctor to ensure that all parts of the human body meet the normal biomechanical requirements and maintain the normal physiological curves of the cervical spine and lumbar spine.

Magnetic Track Lighting is more and more popular on the market.But how to choose the thickness of Magnetic Track Rail?
Must be thick enough.
There are 1.4mm, 1.5mm, 1.6mm, 1.8mm, 2.0mm,2.2mm thickness on the market.Normally 2.0 can be used at ease, is more reliable quality
How to select the copper and plastic conductivity strip in the led magnetic rail?
Use flat pure copper as much as you can
The old products, and we saw most of which is round copper wire, brass containing copper in 59% ~ 68%, and the conductive efficiency is enough. But the circular brass with lamps and lanterns hanging round copper conductive point contact area is lesser, easy to contact but not stable.So sometimes when you move the magnetic track lights and lanterns, there will be a shiny bright, but you don't move the lamps and lanterns, Still can be normal and no problem to use.
Our material is pure purple thickened copper strip, which is more stable to protect the lamp chip power supply.
So ,pls do remember to select the pure flat copper strip when you use magnetic Lighting Track Rail .Don't be cheap for your safety.
