Black bed looks good when the wall colours and other furniture used are in light shades but in such case you have to use a black element elsewhere in the room like a black photoframe, or black pendant light, etc. If you want to choose white bed, it goes well with pastel colours..

Better to choose light colour of bed for your bedroom..with light colour of furniture your bedroom will look more spacious..

Thank you

either go with white colour as it make room look more spacious and bright or else to feel more cozy you can go with veneer sheets
