Underpads, bed pads, and chair pads are products that can help you protect your household items from the effects of incontinence problems. Before selecting your underpad it is important to consider reusability and absorbency. Reusable underpads can be washed and used multiple times. This decreases a number of underpads that you throw away and also is the economical choice. The absorbency level of an underpad is measured by the amount of liquid it can hold without leaking. The absorbing polymer is a substance that pulls in moisture and liquid. The higher the amount of polymer an underpad has, the most absorbent it is going to be. However, larger underpads don't necessarily provide the most absorbency.
