1. First of all, safety first, carefully check the material and workmanship.
The child's body is developing and is very weak, and any undesirable aggression may have a huge impact on the child. There are two main types of damage here: one is visible physical damage, such as bumps, pinching, abrasions, scratches, etc.
The second is invisible chemical damage, such as formaldehyde, benzene and other volatile and radioactive substances (this is more terrifying). Therefore, in terms of materials, we should try to avoid inelastic components such as steel and glass and various synthetic panels (MDF, sandwich panels, particleboard, veneer boards, etc.) that use a large number of adhesives. In terms of quality, it is necessary to choose products that are strong and stable, fine in workmanship, and have been treated with all kinds of edges and corners.
2. It is crucial to have an adjustable function.
The child's body is constantly developing and growing, and too high and too low desks and chairs will adversely affect the child's physical development, hunched over and myopia, etc. Some parents think that as long as the chair is adjustable, the desk is not important. In fact, this is very one-sided, the first step to learn the correct sitting posture is that the feet must be on the ground, and the thighs and calves are at right angles or slightly less than 90 degrees.
Why? If the feet are suspended in the air or stepped on the ground unrealistically, the center of gravity will completely fall on the thighs and buttocks, compress the blood vessels, affect blood circulation, make the child feel uncomfortable, and will inevitably have to constantly change postures, unable to maintain a correct sitting posture, and at the same time easy to fatigue and affect mental concentration; Even if you step on the leg bar of the chair, you can't effectively disperse the pressure on the legs, and this unstable sitting posture will make the child feel unsteady, which has a negative impact on the child's inner stability. Therefore, whether it is a desk or a chair, it is necessary to choose a one that can be greatly adjusted in height to buy.
