Improve the Support of Bed Slats

Step 1

Using a hand saw, cut four bed slats equal in length to the inside measurement of the mattress frame.

Step 2

Check for fit by placing the four boards in the mattress frame at 18-inch intervals.

Step 3

Measure the vertical distance from the bottom of each slat to the surface of the floor and record each measurement.

Step 4

Cut 2-inch by 2-inch board into 4 pieces equal in length to the measurements taken in Step 3.

...

Locate the midpoint in width and length of each slat (cut in Step 1) and drill a through hole in the center using a 3/16-inch bit.

...

Vertically center a 2-inch by 2-inch piece (cut in Step 4) beneath the hole drilled in each slat, and attach it to the slat using a 2-inch wood screw.

...

Insert the slats with the 2-inch by 2-inch leg attached at 18-inch intervals in the mattress frame. This results in four bed slats with a center post (leg) supporting each slat at its center point.
