What are the advantages and disadvantages of the plane and inclined plane of children's learning table?

The tables in the study are all the same.

There are only two "rigid" functions: plane and fixed inclined plane.

In addition to the two states of fixing the inclined plane and the plane,

Why are there no third and fourth desktop states for children to choose from?

It's really sad and ridiculous. It's really a fool.

This also determines that "simplicity" has only three uses for the study table:

The first is to use a fixed slope, and the second is to use a plane.

The third is the alternate use of plane inclined planes,

Moreover, the structure of 12 fixed inclined plane is seriously unreasonable,

There is no scientific basis, it is purely artificial concept hype.

Using "flat surface is harmful" and using "fixed inclined surface" is even more harmful!

In fact,

The height difference between the two states is at least 12 cm.

So that the alternate use of plane inclined planes is more harmful,

Children are more prone to myopia and hunchback.

Therefore, every use will cause certain harm to the child's body and mind.

The study table fooled the parents' money and even fooled the children's health! ?

The manufacturer said that "it is right to fix the inclined plane at 12 degrees", but in fact they just adopted "ignorant means".

Parents say that "a fixed slope of 12 degrees is good", which only shows that they don't know the inside story and deceive themselves.

The desktop can be adjusted at will from 0 to 45 degrees.

The table with constant elbow rest height is what students really need.

Because when reading, the angle of the desktop should be larger, and when writing, the angle of the desktop should be smaller.

There are three kinds of sitting posture of human body: upper body straight sitting posture, trunk forward sitting posture and backward sitting posture.

Different sitting postures require different angles of the desktop.

The change of students' sitting posture in the process of learning is a process in which the human body seeks balance between stability and change in order to achieve compromise.

Really adjust the table according to people's needs,

Infinitely adjustable desktop is the core function of Echo's desk.

And it contains all the functions of the study desk that you think is correct!

This is the greatness of Echo's watch, which belongs to appreciation.
