I used four ikea Lack table (5€ each), two for lights and two for putting stuff that I can easily reach while in bed.
Step 1: Tables
I used reflective plastic sheet bought in an indoor gardening shop and I stappled it inside the tables.
For the other tables, I build shelves but it was not a good idea. It's not very usefull when in bed, It's not very confortable to reach and the room is to deep.
Step 2: Light Cover
The switchs are at the head of the bed. They are not very pretty but they are not very visible.
The bed itself is screwed to the tables.
Electric wires are going under the matress. I put some recharging device in one of the shelf to keep cables hiden.
There is wool pads under the crates to make them slips on the floor.
The crates just fits under the bed. They are not intented for everyday use, I keep things I need from time to time in them.
I should make a crate for the front gap as well.
I'm using this bed for more than a year and it's absolutely stable and robust.
