The whole bed should look like this.

MDF build with 2 glasses shelves and led strip.

To support the frame, I design empty MDF feet on each corner. Probably the most complex part of the bed.

Using Dremel with abrasive head and under a trickle of water, I managed to get nice round corner and a hole for the aluminium tube.

Don't use spray paint indoors ! :)

An aluminum U is embedded in all the edges of the structure for the final touch.

Maybe little bit overkill... but that's all I found in my garage.

Here it is !
