If you lay in the bed, depending on if you are lying on your back or stomach, left and right still change.
Ususally a bed is positioned with the head against a wall, so if you are facing the bed from the foot end, left and right are always the same. So I vote left/right is as seen from the foot end of the bed.
I believe a major factor in this was a ruling by the Hoge Raad that a "free" phone with a contract is unlawful and is actually a loan. Carriers now have to list the price for the phone and for the service separately, so it's a lot more clear what the costs of the phone are.
Also, a "free" phone is now registered as a loan with monthly recurring costs, which impacts for example the maximum mortgage you can get on a home.
