Most shop-built beds are a nightmare to move. This one bolts together with barrel nuts, so it comes apart flat in ten minutes and reassembles rock-solid. That single decision is worth more than any joinery flourish.
The frame carries the mattress on slats — no box spring. Ash is the pick here: it's stiff, it's cheap relative to oak or walnut, and it takes a beating. Maple or oak substitute directly.
The rails are the structural heart. Everything else is trim.
| Item | Qty |
|---|---|
| Ash, 8/4, for legs and rails~$7/bd ft. The rails need thick stock — they carry the whole load.≈ about 59 ft of 3/4" × 6" board | 22 board feet |
| Ash, 4/4, for headboard panel and slat ledgers≈ about 48 ft of 3/4" × 6" board | 18 board feet |
| Poplar or pine, 4/4, for slatsNobody sees the slats. Don't spend ash money on them.≈ about 32 ft of 3/4" × 6" board | 12 board feet |
| Bed bolt / barrel nut hardware kitTwo per rail-to-leg joint. This is what makes the bed knock-down. Do not substitute pocket screws. | 8 each |
| Wood glue | 16 oz |
| Clear interior finish (hardwax oil or wipe-on poly)A bed gets touched every day. Use a finish that repairs easily. | 32 oz |
| Sandpaper, assorted grits | 20 each |
A board foot is a volume, not a length: 144 cubic inches, or a piece 1″ thick by 12″ wide by 12″ long. The “≈” note beside each row shows roughly how much 3/4″ × 6″ board that works out to.
Overall cost: $$$$. Lumber prices vary by region, species, and season, so we give a band rather than a figure we would only be pretending to know.
| Part | Qty | T × W × L |

| LegsAshLaminate two pieces of 8/4 to get 3" thickness. | 4 | 3" × 3" × 14" |
| Side railsAsh | 2 | 1 3/4" × 7" × 82" |
| Foot railAsh | 1 | 1 3/4" × 7" × 62" |

| Headboard postsAshReplace the two head-end legs with these full-height posts. | 2 | 3" × 3" × 40" |
| Headboard panel slatsAsh | 5 | 3/4" × 5" × 58" |
| Slat ledgersAshGlued and screwed inside the bottom of each side rail. The mattress load lands here. | 2 | 3/4" × 1 1/2" × 80" |
| Mattress slatsPoplarSpaced ~3" apart. A queen mattress needs slats no more than 3" apart or foam sags between them. | 13 | 3/4" × 3 1/2" × 60 1/2" |

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.
