The dimension of a weighted blanket's compartment significantly impacts weight distribution, product durability, and sleep quality as the beads are filled inside each "pocket". In the first version of weighted blankets (2016-2017), an 8x8 inch compartment was utilized. In 2019, we progressed to "weighted blankets 2.0," and adopted a more refined 5x5 inch compartment design. In 2023, YNM designed the latest version, weighted blankets 3.0, which refines the 5x5 inch compartment into a precise 2x2 inch pattern and got a new patent.
