What type of latex shop is 9D?

I think what you want to ask is what type of latex pad 9d is, and 9D is more supportive.

9d latex mattress means that the density of latex mattress is relatively high, and the support of 9d mattress is relatively good. If it is 8d, it will be softer.

Mattress d refers to: when designing a mattress, different areas are divided according to the different points where people sleep on the mattress. Different areas should be designed accordingly to make the hardness of the mattress more suitable for people's sleep requirements. The nine regions are subdivided into: head and neck, shoulders, back, lumbar vertebrae, pelvis, thighs, knees, calves and ankles.
