I've been asked to post the plans or email them out. I will but with a strict warning:
BUNKBEDS ARE NOT RECOMMENDED FOR CHILDREN UNDER 10. (by some government agencies, I am not sure which one)
WHY: BECAUSE THEY FALL OUT. A good reason to pause.
I'd never advocate doing anything that might harm your child. But I know my kids better than "Mr.Smith" does. Before you think about building it, think about your kids. Are they crazy hyper maniacs who like to pretend they are super man and jump off the rails of your porch? If so, bunk beds are a bad idea, no matter how old they are.
I tried to think about all the possibilities when I made this bed.
What if he tries and jump out? With the mattress depth it is maybe 3 feet off the ground. I've seen them dive off the back of the couch, so 3 feet does not scare me. You can have it go lower. There is a good 1.5 clearance between the bottom of my youngest head and the upper bunk.
What if he rolls out? My child isn't a big "toss and turner", just in case, he is completely boxed in except at the foot. I guess if I wanted to, I could make some kinda door thingy so It would be like a crib of sorts. However, I think that would be worse than the bunk beds; the oldest might try and climb out.
UPDATE: MY ORGINAL PLAN WAS TO USE 1 X 4 X 60 BOARDS BUT I SWITCHED THEM TO 1 X 6 X 60.
The design was inspired by: http://lilbunkers.com/ndx.php
(7) or (8) 3/8x3x60
Please read through the entire plan and all comments before beginning this project. It is also advisable to review the Getting Started Section. Take all necessary precautions to build safely and smartly. Work on a clean level surface, free of imperfections or debris. Always use straight boards. Check for square after each step. Always predrill holes before attaching with screws. Use glue with finish nails for a stronger hold. Wipe excess glue off bare wood for stained projects, as dried glue will not take stain. Be safe, have fun, and ask for help if you need it. Good luck!
I am unhappy because there ended up being a gap between the mattress support and the outside railing. My little one likes it because it is his cubby hole and my big one likes to throw things down it at his brother.
I haven't fixed it yet. However, I think. a 1x4.5x28 board would cover the gap. It would make it "prettier", it would upset my little one. I am thinking about adding it to the bottom of the top bed to create a cubby for the top bed.
It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed.
