The chair was designed specifically for the four thousand guests invited to the Prince of Wales's Investiture at the Medieval Caernarfon Castle in July 1969. Millions of television viewers watched the twenty year old Prince receive his insignia from The Queen, conferring on him his new title as the twenty first Prince of Wales. Lord Snowdon, the Prince's uncle and Constable of the castle, was commissioned (along with Carl Toms and John Pound) to design the setting and furniture of the investiture. The resulting ceremony successfully reflected the supposed "antiquity" of the event, but with a simplified modernist twist- very much in tune with Sixties thinking: the investiture taking place under a huge Perspex canopy, a modern take on the hangings which might have been found, say, at a Medieval tournament.

For the Prince of Wales's Investiture, 4,600 chairs were made and sold for twelve pounds at the end of the day. Immediately after the ceremony, the chairs were dismantled and offered for sale. Invited guests had first refusal, with the remainder being sold to the public. Lord Snowdon bought six. The chair is made from Welsh beech, stained in vermillion, and consisting of a seat and back resting on a tiered stand. The Prince of Wales' feathers motto (Ich Dien) is indented in gilt (rather than painted) to the chair back, a successful attempt to reduce wear. The seat is padded with foam and upholstered with a simple red Welsh tweed. It was imperative that the chairs could withstand rain, and that no colour came off on the guests' clothes.

A further example is held by the Frederick Parker Chair Collection.
