Custom Super King Four Poster Bed

This was a really enjoyable project, designing and building a Super King Size Four Poster Bed (1.8meters wide, by 2 meters long), at just under 2.4 meters high (to fit within a standard ceiling height).

I primarily began making it for myself, but then later sold it to a very happy customer when I moved onto the boat.

The materials were exclusively NZ Radiata Pine ply (18mm thick), produced at a saw mill within NZ.  Finished with NZ Linseed oil.

The whole design was screwless, utlising 40mm box joints on most of the 90 degree joints.  And then 8mm dowels with wood glue was used everywhere else.

Sixteen marine grade (316) Stainless Steel bolts were used to complete the assembly, ensuring the whole bed could be packed down and transported in less than 20 minutes (the columns were designed to nestle inside each other when stacked together).

Matching letters were engraved into the respective internal faces of each joint, so no seperate instructions were needed, just ‘match the eight letters’.  The only tool needed was a 13mm spanner, so no allen/hex keys to loose.

The bed also featured an optional Unistrut railing system (not shown in these pictures), allowing highly flexible attachment points for play, both under the outer edges of the bed base, up the inside corners of each post, and a fully movable rolling rail system enabling rated suspension points, that could be moved anywhere within the 3Dimensional space within the columns, above the mattress, and right to the top of the columns.
