Queen Platform Bed Frame

Mill everything to final dimension, then stack it with stickers and leave it two or three days. Freshly milled stock moves as internal stress releases. Building immediately means building with wood that's still changing shape.

This costs you nothing but patience and saves you a twisted rail.

Glue up 8/4 pairs to get 3" square legs. Clamp well, cure overnight, then mill the laminated blanks square.

The two head-end legs are full-height headboard posts (40"). The foot legs are short (14").

Each rail gets a tenon on both ends: 1/2" thick, 4" long, centered, shouldered all around.

These tenons are for alignment, not strength — the bolts carry the load. But a sloppy tenon means a bed that racks, so cut them to fit snug by hand pressure.

Mortise each leg to receive its rail tenons: 1/2" wide, 4" tall, 4-1/4" deep. Router with an edge guide, or drill-press-and-chisel.

Dry fit every joint. The frame should stand up on its own, square, before any hardware goes in.

The step to get right. Drill a bolt clearance hole through the outside face of each leg, through the mortise, and into the rail tenon.

Then drill the cross-hole in the tenon for the barrel nut — on the drill press, dead perpendicular. If that hole is off by more than a couple degrees, the bolt will not thread into the barrel nut and you will be fishing around inside a rail with a flashlight, cursing.

Test every joint with the actual hardware before you finish anything.

Groove the inside faces of the headboard posts and the head rail. Slide the panel slats in dry — do not glue them. A 58"-wide panel of solid ash will expand and contract across the seasons by nearly 1/4". Glue it and it will crack.

Let it float. That's the whole trick to solid-wood panels.

Glue and screw a 3/4" x 1-1/2" ledger along the inside bottom edge of each side rail. Screw every 8" — this joint carries the mattress, the sleepers, and everything that happens on the bed.

Don't rely on glue alone here.

Sand to 180. Finish every part while they're still separate — you will never reach the inside corners once it's bolted together.

Three coats of hardwax oil or wipe-on poly, sanding lightly at 320 between coats.

Carry the parts in flat and bolt it together where it's going to live. Ten minutes with a hex key.

Drop the slats in loose, spaced ~3" apart. Don't fasten them — loose slats are quieter and let you pull one to vacuum under the bed.

When you move house, it comes apart the same way.
