I would caution against using something like this for a bunk bed or loft bed. It’s a potentially fatal accident waiting to happen. At the very least, you should stick to a design that has been thoroughly tested and rated for load. Even so, the temptation to modify it is always there, especially for kids. And as a parent, it may not be obvious when it’s been modified because there are holes all over the place. As you…

That bunk bed design looks pretty flimsy to me. Yes, there's a set of cross cables across part of the back and across one end, but the rest looks like it would parallelogram pretty easily.

Tip for people trying to advertise something: You have a limited amount of time to get people's attention. Once a video is longer than 2-3 minutes, people's willingness to even start watching it goes down, and you better show something interesting in the first 20 seconds. 1 minute into the video is the first time they even mention the product. Which happens to look suspiciously like standard pieces I've seen in the h…

Also, if your YouTube hosted video that’s an ad for your product has other ads inserted into it by the platform, it’s probably too long.

This is, in fact, just a (more expensive) version of 80/20 Ready-Tube with a wooden option, which is really nice (80/20 is aluminum only). It should be compatible with existing 80/20 hardware. 80/20 also offers project plans for some furniture: https://8020.net/xdiy1601

Wow, I made an account to download the BoM and that coffee table’s total price of materials is $1108 and the end table is $1378. I was expecting less than half that.

If I have to almost design my coffee table from scratch, including sawing all the pieces to length, then I don't really expect the parts to cost much more than $30. The real investment was my time...

I came to post this. I got this spiral bound techno hippie book at the bookstore when I was 12. Blew my mind.

For an even more customizable solution check out 8020(1) They’re not cheap, but they have engineers on staff who will help you finalize your project. I’ve used them for several things in the past and have been quite happy. (1) https://8020.net/

The video was not produced by the people making Grid Beam, but by Kirsten Dirksen, who covers all kinds of DIY/Sustainable/etc. unique and largely housing-related things https://www.youtube.com/@kirstendirksen

This is pretty much real scale lego.

Literally! The mathematical requirement for grid beam is that the width of the beam matches the hole-to-hole distance in the beams. Lego technic beams are 8mm wide, and the hole-to-hole distance is 8mm. Lego is small-scale grid beam.

Example grid beam tri-joint made with Lego Technic pieces: https://twitter.com/hugs/status/1619804592199577601

I generally agree, especially for kids' furniture, but the pre-drilled grid-beam compatible beams from McMaster-Carr[1] (which is likely just 80/20 Ready Tube) are incredibly strong. I've made a bunch of office desk & table structures and they are still going strong years later.[2][3]

There are two separate concerns here. Is the design adequate? Will children do something risky? "Yes," and "Yes" irrespective of how their bed is built. Conversation is the second best way to address the second "Yes." Play the best way.

That’s why designs of things like beds have to prevent them getting their necks caught, for example. There was a carpenter selling custom beds in the UK, but there were a number of fatal accidents because he hadn’t designed it properly.
