1. Build the frame
“Fits a twin sized mattress. It’s 74 inches long and 38 inches wide.”
4. Make the frame of the lower platform
It is 8 feet long and 7 feet wide.
5. Two of the magnets got stuck together due to bad packaging in the shipping process
“This is incredibly bad news because there are several hundred pounds of force holding these together now. After a lot of raging and angrily emailing the company that I got the magnets from, I realized that a rubber glove I was handling the magnets with was stuck between them. It provided a gap of around 2mm. I used scissors to pry this open and stick successively larger things inside.”
He threw a bunch of screws in there since he was worried the pens would fall out
“I was worried that the pens would fall out and I would lose all of my prying progress, or that all of my spacing would fall out and they would be entirely stuck together with no gap, in which case they would be entirely and impossibly stuck together (many hundreds of pounds of force holding them together, these are solid neodymium rare earth magnets the size of hockey pucks). I used screws, which since they are magnetic, stood no chance of falling out! They also worked pretty well to prop them apart.”
“I stomped on the spacers to jam them and a pen in. I then replaced the pen with a third spacer and got them unstuck!”
“Slight damage. Essentially only aesthetic. Tests I did confirmed that the magnets were for all intents and purposes entirely functional.”
7. Put it all together
“Steel cable tethers the top bed to the bottom base. Had to do some math to determine how long the cable needed with how high I calculated that the bed would float. I got this stabilization system (and most of the idea of the bed!) from this bed which is a much larger scale, much more expensive version.” See the video below.
