This bed is made using the Farmhouse Bed plan from page 136 in Ana's book. We just had our kitchen remodeled, so I took the cabinet doors and swapped those out for the 1x10's in both the headboard and foot-board. The cabinet doors took a while to strip the paint off and I used paint stripping sandpaper for that. Once the cabinet doors were stripped, I cut 1x2's for the two center dividers and 1x3's for the two outer dividers to get the desired width. I then stained the cabinet doors and dividers before attaching them to the 1x4 trim. I did not get 4x4's, so I cut 2x4's to length and glued and screwed them together.
Our mattress does not use a box spring, but slats, so I borrowed slat directions from Shanty 2 Chic's platform bed and our old IKEA bed frame. I used 2x2's for the supports and 1x4's for the slats. I used scrap 2x2's to support the center slat support and attached the side 2x2's to the bed rail (1x6 vs. 1x10 due to matress depth) with glue and screws.
