Hi and thanks for inquiring. The entire pouf is made of varying polyester materials and Poly does not hold moisture. So, any moisture that hits it, will drip right through and be dry quickly:) The water would seep through and probably good to move the item away from the small puddle below it to help dry. We have two on our back patio and that's what we do. Anyway, hope this helps. Thanks again! DiaNoche Designs
