ABSTRACT:
A water chair which is particularly suitable for use by convalescent or geriatric persons and which comprises a frame having a seat portion and a backrest portion, a plurality of bag-like slings secured by their upper edges to the backrest portion, and a water impermeable bag located wholly within each sling. The bag within each sling is partially filled with water and the space within each bag which is not occupied by the water is substantially free of air whereby the bag and its containing sling will function as a cushion which supports and adapts to the shape of a user of the chair. The bag within each sling is secured to and suspended within the sling so that it does not collapse upon itself when partially filled with water.
