For Everyday Moisture Control
Moisture can collect underneath a Futon Mattress during sleep, especially when it is placed directly on flooring. Dry-Well helps keep this area drier.
It is useful during humid seasons or when it is difficult to air your Futon Mattress outdoors regularly.
The sheet is thin and lightweight, making it easy to dry, fold, and store.
Moisture absorption capacity: approximately 650 ml.
