During WWII, South Hill Park was the evacuation home of the Royal Sea Bathing Hospital from Margate. Patients, including very many children, were suffering from surgical tuberculosis. Treatment involved being outdoors day and night, those with a diseased spine restricted to a plaster bed, or those with infected joints with splinted limbs. Pre-antibiotic treatments, at that time if the disease abated the best possible outcome was an immobile back or limb - forever seized up into the least worst position.
Commemorating this time in South Hill Park's history, the outdoor installation of 'beds' and pillows also celebrates that children in this country are largely now free of this disease. Children are free to play with 'loose parts' both in the sense of their limbs, and in the free-play sense of Simon Nicolson's 'Theory of Loose Parts'.
