ABOUT BON ACUPRESSURE MAT ↡ Bed of Nails® is the original acupressure mat brand that started the global acupressure mat movement. Unlike most acupressure mats, Bed of Nails uses more spikes per mat to distribute body weight more evenly across the surface. This spreads pressure across many contact points, creating a more balanced and comfortable acupressure experience while stimulating many points at the same time. Each spike plate contains 42 non‑toxic, recyclable spikes. Natural buckwheat‑filled acupressure pillow designed for curved areas of the body. WHAT HAPPENS AND HOW IT FEELS ↡ Initial contact creates a stimulating prickly sensation. After a short time many users feel warmth and tingling as the body relaxes into the pressure. HOW TO USE BON ACUPRESSURE MAT ↡ Use under neck, spine, or feet during relaxation sessions. BON ACUPRESSURE MAT SPECS ↡ 2,142 spikes, organic linen cover, buckwheat hull filling. Dimensions: 14.5 x 6 x 4" (38 x 15 x 10 cm)
