Lazy bed (Irish: ainneor or iompú, Scottish Gaelic: feannagan [ˈfjan̪ˠakən]) is a traditional method of arable cultivation. Rather like cord rig cultivation, parallel banks of ridge and furrow are dug by spade although lazy beds have banks that are bigger, up to 2.5 metres (8 ft 2 in) in width, with narrow drainage channels between them. It was used in southern parts of Britain from the post-Roman period until the post-medieval period, and across much of Ireland and Scotland until the 19th century.
