Environmentally friendly and quickly assembled flat pack coffin

Flat-pack coffin made of environmentally friendly materials, comprising a lid 10, side and end panels 20a, 20b, 30, 40 and a base 50, wherein each side and end panel has protrusions on a bottom edge for insertion into the base. The side panels each have a slot on an end edge for accepting a connector on each end panel. The base comprises a slat layer, with a padded layer on top to form a resting surface for supporting a corpse that has upstanding edges defining a perimeter rim with apertures for accepting the protrusions of the side and end panels. The panels may be formed of a frame with a fabric cover. The padded layer may have crossed slats interspersed with stuffed fabric bags. The protrusions may have either a laterally extending nub or a hole to receive a pin, and the base apertures may have a narrowing, stepped cross-sectional internal profile. The connector may be a hook.
