The smaller the chambers of a weighted blanket are, the better the glass beads get distributed inside the blanket. This prevents the glass beads to move around inside the blanket and causes less noise during the night.
The size of the chamber also affects how the weight of the blanket is perceived. For example, blankets with large chambers can cause uncomfortable pressure points due to the higher weight per chamber.
