Many parents complain that the crib they have purchased is not practical: they will either have less opportunity to use it, use it several times or use it, or find that there is a defect that they do not dare to use. And the more they buy brand-name high-priced products, the stronger the sense of loss. The reason is mainly the lack of experience. To be honest, it is not easy to choose products that are truly suitable for babies in a variety of cribs. The following are the professional opinions of the people in the industry and may be helpful for your purchase of baby cribs. First, safety first (1) The structure is safe and reasonable: the fence height is 65--70CM, and the spacing standard between the fences is 5.5CM; (2) Material safety: wood with knots cannot be used in load-bearing parts, otherwise it is prone to fracture. New Zealand pine is the best material, birch, teak, ash, beech, etc. is also a good choice. (3) The bed is safe and secure: on the market, synthetic bedboards are used at the bottom of the bed, and cribs placed on the inside of the bed are very dangerous. In Europe and America, cribs use iron bed bottoms and solid wood bed bottoms. There are stringent requirements for the design of the connection between the bed and the bed body and the connection hardware used. Generally, embedded or suspended connections are used, and wood and The connection to the metal bed is made of non-slip screws. (4) Environmental protection and safety of paints: The first is the smell, the second is the composition, and the crib paint does not contain harmful components such as heavy metals and formaldehyde. The crib of colored paint is very good for children's visual development, but the coating is thicker and hides the true colors of the wood, and the safety of the wood material is very important to the baby. If you choose unpainted cribs, it is advisable to apply natural wood oil after a period of use to prevent the wood from being deformed by moisture. (5) The safety of accessories: The open accessories of the side guardrail are mainly: rotary type, pull type, slide type. The material of the accessories determines the service life of the guardrail. The material of the pulley is ordinary plastic or recycled plastic, engineering plastic, nylon, iron, stainless steel and so on. Nylon and stainless steel materials are better and the price is higher, but the service life is relatively long. Cribs with wheels are easy to use, but care must be taken to ensure that there are safe brakes on the wheels and that the brakes are secure. Second, the function of the second Extension function: If you want to choose a child's bed that can meet your child's needs in each period, you need to adjust the stretch function. The majority of cribs produced in China are about 120CM, and can be used for around 3 years old. The length of cribs in Europe and America is about 140CM, and the width is about 78CM. It can be used around 6 years old. The size is reasonable and it takes longer. Swinging function: There is a relatively big controversy and it is still to be studied whether the structure of the baby's head and bed is safe. Bed level adjustment: You can choose the 2-4 adjustment, which can meet the needs of your baby in different age groups. Side Guard unilateral lowering control: can reduce the risk of accidental release of the baby. It is recommended to choose a crib that is simple in function, reasonable in size, and structurally sound. Third, the installation of crib Pay attention to whether the distance between the connection holes of the bed boards is tight, the accurate hole position makes the bed assembly easier, and the operation is more convenient, which can better reflect whether the work of a bed is fine. Fourth, the choice of mattress Soft or hard mattresses are not conducive to the growth of the baby's bones, according to the baby's weight to choose the appropriate hardness, the best players feel flexible, good support of good quality mattress. Such as natural coir and natural latex mattress, elastic support moderate, breathable, insect-resistant, anti-mite, anti-mildew. However, copra mattresses sold on the market are also synthesized with chemical adhesives and are not suitable for infants. If there is any gap between the mattress and the bed frame, special attention should also be paid. If it is, it means that the mattress is too small and should be replaced to avoid the baby's fingers sticking inside. The thickness of the mattress is generally more appropriate in the 5-10CM, the maximum thickness should not exceed 13CM.
