I currently have a king size with slats using softwood at far smaller sizes than mentioned here, but there is 4 corner legs AND middle floor supports which are not wanted on a single bed that is to sit above a desk. Hence all the questions I have about elevated bed designs.

Let me ask this in a clearer way.... What is the bend strength of 10mm thick pine? What is the bend strength of 20mm thick MDF? When both pieces are 60mm wide and 1 metre long! What is the maximum weight to deflect each by 20mm?

Yes. And breathing etc. Normal body processes. I also know that due to a slatted bed I used to have that then had hardboard placed over the slats, caused mould to grow. The mattress needs to be flipped EVERY day to stop this. At least with breathable slats, the mattress doesn't need to be...

"After all 200kg is more than two adult men weigh" I weigh 139kg so that is false! I was guessing the slat thickness, but an IKEA slide out kids bed uses slat approx 6-10 mm thick and or not knot free either and they break (I had to replace two of them already)! Still nothing about the relative...

What I am trying to ascertain is normally soft wood slats about 1/4" thick are suggested for beds. But would 3/4" thick MDF provide the same support? Or even 1/2" thick? I know the same thickness will not work as soft wood is stronger. But how much stronger?

I was assuming the 200kg for the weight of a full grown adult plus mattress, sheets etc. For just the individual, let's assume 140kg instead (without mattress, pillows, duvet, sheets, coverings, etc a mattress alone is heavy and could reach 50kg)

Is it possible to make a bed frame for a 200kg adult that is only supported on the floor by 60mm X 60mm square legs in the corners. This will be over a bench so I can have a computer bench/table underneath and be able to sit under the bed to work and sleep in the bed above.
