It is called a three-dimensional cutting platform. Professional platforms are generally made of PU material, which can be used for straightening and ironing. The material is characterized by high density, not easy to hang needles during use, and long service life (low-end platforms generally use styrofoam, which cannot be ironed, and direct sales are easy to break, bump and shrink).

The other is the inclined pin, which is generally made of glass fiber reinforced plastic, which is the material selected for the board room model.

I hope my answer is helpful to you.
