I built this bed in July in anticipation of my two children sharing a room for the first time. They love it. In August, I thought to add the $10 ledges to the frame of the bed when I realized our walls wouldn't support their weight and we're in a rental. I used 1x3s instead of 1x4s those plans called for so the shelves would sit at the same depth as the 2x4s on the frame of the bed.
I wish I knew more about painting soft wood because I don't love how the paint job turned out, though it is green per my son's request. I couldn't deal with more green, hence the ledges are stained.
I love the little alcove this has created. I added curtains and we read stories in there every night. Thank you so much for the inspiration and plans!
