What does section A and section H mean in furniture

Paragraph A can express three meanings:

1.Grade A goods.

2.High-grade goods.

3.Out-of-code goods.

H stands for height, which is the height of the furniture when people are facing it.

The general order of writing is W*D*H.

W stands for width, which is the distance from the left hand to the right hand when facing the furniture.

D stands for depth, which is the distance from the front to the back of the furniture when a person is facing it.

The more special thing is the bed, because the front of the bed is the head of the bed, which is the way people stand at the end of the bed and look at the head of the bed, so the standard method of the bed is generally 1560W*2160D*960H. Others rarely have a depth that exceeds the width.
