These types of boarded chairs for young children were developed from the 1700s and used in Wales throughout the 1800s. They were like portable nurseries: the child could be restrained in the chair with the use of a bar that ran from one side to the next. Underneath the seat there was space to place a hot brick to keep the baby warm and also there was a hole for a chamberpot. Many were made with a play table or feeding tray and they could be easily carried from one room to the next using the carrying handle. Some could also be rocked.
