What is the difference between the 7.0 mm needle pitch and other densities, and how does it affect the sensation?

The needle pitch of 7.0 mm refers to the distance between the centers of adjacent needles on the mat. This specific spacing creates a balance between coverage and intensity. Because the needles are not packed as tightly as in high-density applicators, the pressure is distributed across a broader area with each needle bearing less individual load. This results in a sensation that is distinct from very dense mats, which can feel more concentrated and potentially more intense on sensitive areas. The multi-metal construction of the needles adds a unique thermal and tactile quality to the stimulation, which many users find helps in distinguishing the pressure points more clearly. For those new to acupressure mats, this pitch offers a manageable entry point that allows the body to adapt to the mechanical stimulation without being overwhelmed. It is particularly effective for larger surface areas like the back or abdomen, where even distribution of pressure is key to relaxing tense muscles. If you prefer a sharper, more focused sensation, you might look for a smaller pitch, but the 7.0 mm option is designed to provide a broad, even effect that covers substantial body parts efficiently.
