What vastu suggest for bedroom furniture is as follows:Bed must be built with wood, avoid metal bed. Place the bed in a way that foot of bed shoud be in north direction but not face the doors. Do not place bed under beams or in corners.
Cabinet should be placed in south-west of the room opening towards North. It should be placed leaving south-east, north-east, south-west, north-west corners and east and north directions of the room.
Television should be avoided in bedroom but if you have to, place it in south-east of bedroom and other electrical appliance should also be placed in south-east. Mirrors also avoided in bedroom.
Still if you want detailed explanation, I would suggest you to hire a full time vastu consultant, who can visit you and advise you accordingly.
