The environment-friendly coffin according to the invention comprising a box assembly and a profiled lid assembly covering said box assemblies, with both assemblies being connected to each other by means of connecting elements, is characterised in that the coffin's box assembly (1) comprises a casing (3) made of natural stone plates, plate-shaped flats (10) with tapped bores (11) made in them, fixed to inner or outer surfaces of longer plate side walls (5) of said casing, plate-shaped metal washers (12) with tapped mounting bores (13) fixed to these inner side walls (5) and a tubular element (15) mounted inside casing (3), said element tubular being made of glass fibre mat or metal and fastened to inner surfaces of plate side walls (5) and to bottom (4) made of natural stone slab or made of natural stone slab and plate (27) made of a made of a wood-base material and fixed to said stone slab by means of glue-based sealing mass (17), whereas the profiled lid assembly (2) of the coffin has an outer casing made of natural stone in the form of a solid with bottom cascade-shaped cavity (23) or with trough-shaped cavity (32) with a profile of the truncated pyramid, with a lower side offset in the form of a slab frame (29), where in the inner surface of said casing there is insert (30) made of a wood-base material with the same profile fixed by means of a glue to which glass fibre mat (31) is glued.

The present invention relates to a coffin with a lower side and an upper side. Said coffin comprises a structure and an inner lid, where the structure includes a first frame located on the lower side of the coffin, a second frame located on the upper side of the coffin, a plurality of ribs connected to the first frame, protruding towards the upper side, and connecting the second frame with said first frame, and a covering surface connected to the ribs. In turn, the inner lid has an arcuate shape and is arranged on an inner side of the second frame, where the ends of the inner lid arcuate shape lay on the ribs of the structure. Moreover, in some embodiments of the invention the coffin comprises at least one retractable handle arranged on the cover surface. Said handle can comprise a handgrip, a lanyard connected to the handgrip and to the first frame; and an elastic element connected to the cover surface and coupled to the lanyard. The elastic element is set up to exert an elastic force on the lanyard that allows for the handgrip to be drawn towards the cover surface.

The invention provides a flat-pack coffin made of environmentally friendly materials, the coffin comprising a lid, left- and right-hand side panels, head and foot end panels and a base assembly, wherein each right- and left-hand side panel independently has a top edge, a bottom edge, a head end edge and a foot end edge, each side panel independently being provided with a plurality of downwardly extending locking protrusions on the bottom edge for insertion into the base assembly and a slot on each end edge for accepting a connector from an end panel; wherein each foot and head end panel independently has a top edge, a bottom edge, an interior face and an exterior face, each end panel independently being provided with a plurality of downwardly extending protrusions on the bottom edge for insertion into the base assembly and connectors on the interior face for insertion into the slots in the side panels so as to secure the end panels to the side panels; and wherein the base assembly comprises a layer of base slats, and a padded layer on top of the base slat layer to form a resting surface for a corpse, wherein the resting surface has upstanding edges defining a rim around the perimeter thereof, the rim having a first plurality of apertures for accepting the downwardly extending protrusions of the end panels and a second plurality of apertures for accepting the locking protrusions of the side panels so as to secure the side panels to the base assembly.
