This is a bed frame's worth of tall posts, not a full canopy kit — the 4x4 legs run a full 80" so there's real height to work with if you build a canopy topper afterward, but the topper itself is a separate addition and isn't part of this cut list. What this plan does specify completely is the frame underneath it: a plywood panel let into each post pair for the headboard and footboard, trimmed top and bottom, joined to 2x10 siderails, and carrying a center-supported slat platform.
The slat system is what actually needs the most care at queen size: a plain pair of siderails will sag under a queen mattress and sleeper without help, so a center cleat-and-leg assembly runs down the middle, and the slats rest across both the siderail cleats and that center support rather than spanning the full width unsupported. Every pocket hole gets drilled before assembly, not after — the plywood panel is captured between the legs on final assembly, and there's no reaching those joints again once it's in.

Drill two 1-1/2" pocket holes on each end of the headboard rails and attach them to the 4x4 legs with 2-1/2" pocket hole screws.
Drill 3/4" pocket holes on the top and sides (not the bottom) of the panel's back face, spaced about 8" apart. Attach the panel to the legs with a 1" gap behind and 1-1/2" gap in front, using 1-1/4" pocket hole screws — this sets the panel back 1" from the front edge of the legs. Attach the 1x4 top trim to the top of the panel with 1-1/4" brad nails and glue.
Repeat the headboard steps to build the footboard, with its shorter panel and top and bottom trim pieces instead of just a top trim piece.
Paint or stain the headboard, footboard, and siderail pieces before moving them into the room. Drill two 1-1/2" pocket holes on each end of the siderail top rails, and three 1-1/2" pocket holes on each end of the 2x10 siderails, then assemble the bed with 2-1/2" pocket hole screws.
Build the center support framing from the slat cleats and center legs — a queen-size platform needs this center support to keep the slats from sagging under a mattress and sleeper.
Lay the mattress slats across the siderail cleats and the center support, and screw down. Keep no more than a 4" gap between slats — check your mattress manufacturer's recommendation for the right slat spacing.
Optional 1x2 trim can be added around the top edges of the headboard and footboard panels for a little more visual dimension.
