This was a fun project. I got to work with my brother on this one. We built two of these beds for my parents’ house for when the grandkids sleep over.

My brother is an avid DIYer, so he’s very handy with tools, but hasn’t really done much woodworking. I got to show him some basic woodworking techniques and how to use a planet, etc. It was a fun time. He was the lucky one to climb through the attic to attach those cables!

Anyway, they are made out of poplar with some DIY steel brackets to hold the ladders and long side rail. The long rail is removable to change the sheets. As you can see in the photos, the ladder is detachable (so little kids aren’t climbing when they aren’t supposed to be) and hangs on the long rail.

They are still waiting on paint, but before we can do that, mom needs to settle on a color!

Looks great! Good idea on the ladder storage. Did you borrow an aileron cable for the support?

Haha… Would have probably tripled the cost!

And tripled the safety. What is the dynamic test on that cable?

I’m so glad you didn’t tell us it’s attached to an eye screwed vertically into a joist. A vertical screw will eventually pull out under a dynamic load. It has to have a thru bolt attachment to the fixed support. I make this point for others who might be unclear. A vertical lag bolt will literally only be holding on by threads.

You have to know that the kids will be jumping and swinging on it like a trapeze. At least double up the cables as a fail safe.

No, it’s not attached veritically. It’s a through bolt, horizontally through structural framing. Additionally, the bed is attached to the wall with 5 5/16” lag bolts. There is no where near enough weight on that cable to snap it. The cable is good to 740 lbs. Even if I cut it, the bed would tilt, but would not fall off the wall.

If someone wants to put their child’s safety at risk, that’s their business, not mine.

Looks great! Looks like the cable clamps may be on backwards however. A bit hard to tell. Rule of thumb is “never saddle a dead horse”. The U bolt part of the clamp should be on the short, “dead end” of the cable. Greater slip resistance. If I’m seeing it wrong, ignore this post.

You know, I’m actually not sure. I’ll take a look. Thanks for your input!

That looks great and the storage for the ladder would reduce the chance of carpet compression while making it easier to vacuum underneath. Is that a regular twin sized mattress?

Fixed and floating fasteners both have their place in dynamic and static loading applications. The math doesn’t lie!

Yes, standard twin.

I know it’s been a while since comments were made on this post but we are getting ready to do this for our daughter and I have a question.
The through bolt that’s in the ceiling joist… how do I do that exactly? How is the cable attached up there? I am a visual person but if someone could explain it I think we could figure it out.
Thank you all for any help.

If I could easily access that space, I’d take a picture for you, but it’s in a very difficult-to-access part of the attic.

We drilled a hole in the joist and put an eye bolt through it. Clamped the cable in the attic, just like the one in the picture. Hope that helps.
