What’s the differences between 5D and 7D car mats?

I mean come on, 5D and 7D? these are false concept, just sellers marketing gimmick to attract attention, they really don’t mean anything. But if you have to ask, I’ll have to explain what are 5D and 7D car mats first:

What is 5D car mats? 5D car mats are a type of advanced automotive floor mats that offer a significant upgrade over traditional mats in terms of design, fit, and functionality. The term "5D" signifies the integration of five-dimensional features or layers in their construction, each aimed at enhancing performance, comfort, and protection for a vehicle's interior. Here's a breakdown of what typically constitutes a 5D car mat: Top Surface Layer, 3D/Embossed Layer, Waterproof Layer, Shock Absorption/Cushion Layer, Anti-Skid/Backing Layer.

What is 7D car mats? 7D car mats refer to a “newer” generation of advanced automotive floor mats that are designed to offer the highest level of protection, comfort, and custom fitting for a vehicle's interior. The term "7D" signifies the inclusion of seven distinct layers or dimensions in the mat's construction, each serving a specific purpose to enhance the overall performance and aesthetic appeal. Here's a breakdown of what constitutes a 7D car mat, which are: Top Layer (Surface Layer), Padded Layer, Waterproof / Spill-Resistant Layer, Noise Insulation Layer, Anti-Slip / Stability Layer, Custom Fit Layer, Bottom Layer.

By understanding those concept of the so called 5D or 7D car mats, you should know now SHARGGE car mats are typically 5D car mats or 7D car mats, because it dose all the work that they can do, like atheistic top layer, soft cushion layer, water proof top layer, noise insulation cushion layer, anti-skid bottom layer, SHARGGE can do all of this with 3 layers, that’s why we usually call SHARGGE 3D car mats, not 5D or 7D car mats, Because that is not what we do in our normal life.
