Cut the longest cuts first to make sure you get those cuts before cutting smaller pieces

DO NOT cut boards in half for transport - cut according to cut list

Cut 1x and 2x boards with a compound miter saw (recommended) or a circular saw with straight edge.

Plywood needs to be cut with a circular saw or tablesaw.

General Instructions

The finished bed will be large in size and may not fit through a door opening.  You may wish to build in pieces, finish pieces that are exposed in final product, then move into the room for final assembly

Instructions

Step 1

Drill two 3/4" pocket hole son each end of the 1x6 boards.  Drill three on ends of 1x10.

Attach with 1-1/4" pocket hole screws to the 2x4 legs, flush on inside, pocket holes on inside.

Step 2

Glue and nail 1/4" plywood to end panels.  

Step 3

Cut ladder top legs at angle with circular saw or miter saw - shown with 30 degree angle.  Leave 3/4" at top flat.

Build ladder with 2-1/2" self tapping wood screws.

Attach from back with 2-1/2" self tapping wood screws.

Step 4

Drill 3/4" pocket holes on ONE end of the small 1x6 pieces.  Attach to 2x4 legs with 1-1/4" pocket hole screws.

Attach to top of ladder with 2-1/2" self tapping wood screws.

This completes the two end panels.  Finish the entire end panels as desired.

Step 5

Build two identical drawer support frames as shown - the must match exactly for the drawer slides to slide correctly.

Use 2-1/2" self tapping screws or 2-1/2" pocket hole screws to build.

Step 6

Paint or stain the 2x4 drawer frames and the 1x6 side rails.

Drill two 3/4" pocket holes into each end of the 1x6s.  

For the bottom siderails, also drill a few 3/4" pocket holes facing downward to attach to the 2x4s on install.

Attach 1x6 to the ends with 1-1/4" pocket hole screws and glue.

Attach 2x4 drawer framing to end panels with 2-1/2" wood screws.

Attach bottom 1x6 siderail to the 2x4s with 1-1/4" pocket hole screws.

Step 7

Attach drawer rails to insides of 2x4s with pocket hole screws - use 3/4" setting and 1-1/4" pocket hole screws for 1x material, use 1-1/2" setting and 2-1/2" pocket hole screws for 2x materials.

*Some parts missing to enable a better view of interior of bed

Step 8

IMPORTANT: Check bed for square.  Take diagonal measurements from opposite outside corners and adjust until both diagonals match.

Cut 1x2 trim boards to fit and nail and glue to top of bed.

Step 9

Check for square.  Add bed slats and nail or screw down.

Nails are less expensive and easier, but harder to remove.  If using screws, use 1-1/2" screws (or close in length)

Step 10

Trundle

Lay 2x4s on a flat surface.  Place slats on top.

Adjust for square - opposite diagonals MUST match.

Nail and glue slats to 2x4s.

Step 11

Add back and sides to the trundle.

Recommend: Drill 3/4" pocket holes on top end of the 1x6s and attach with 1-1/4" pocket hole screws at top.  Also drill for attaching the front in next step.

Step 12

Add caster wheels, three on front and three on back, to the 2x4s.  

Place trundle inside the bed.

Step 13

Position the trundle face over the trundle and attach with screws.

Step 14

Read instructions with your drawer slides.  This drawer tutorial assumes each drawer slide needs 1/2" clearance (1" overall).  If you drawer slide differs you will need to adjust your drawer cuts.

Measure drawer openings and confirm the openings are 23" wide.  If not, you will need to adjust the drawer width.

Build drawer boxes.  

We recommend pocket holes on the outside (will be covered in later steps by drawer face)

Check drawers for square.

Glue and nail the plywood bottom to the drawer boxes.

Step 15

Install drawers inside the openings with drawer slides.  INSET 3/4" from front edge of 2x4s to allow for the drawer face.

Cut drawer faces 1/4" smaller than opening.

Place drawer face over installed drawers.

Attach with a couple of 1-1/4" nails (avoid areas where knobs or pulls will be installed)

Remove the drawers and attach from inside with 1-1/4" screws (you can use pocket hole screws)

I also love this bed but need a full size bed...other than the size, it is perfect in every other aspect.  I would love it if someone could tell me how to modify the plans for a full.

I'm just finishing one of these. The standard mattress I bought is a bit to long for the trundle, which slides under the main bed and is therefore shorter. The one she refers to is surprisingly comfortable but fits perfectly. I'd imagine you could make the entire bed a few inches longer and and use a standard mattress.
