IKEA MALM bed. They are quite close to the top, as you can see on the picture. I think it would be just as good or better to use hooks instead of nails. Then I simply laid the light tube with LED's on top of the nails. (The light tube is resting on the nails). Done! Simple and cheap. I think it gives our bedroom a cozy atmosphere and I have had it like this for a few years now."
