As per Vastu, there are a few directions that are good for you, and at least one that must be avoided at all cost. 

The headboard of your bed must be in the south or west direction in the master bedroom. This ensures that your toes point towards the north or the east while sleeping.

The south is the best direction to place your head while sleeping.  According to Vastu, this position is linked with prosperity and happiness and, most of all, the best quality of sleep.

For children’s bedroom, the headboard should ideally be along the east. Doing so helps improve health and concentration, and kids get to benefit from such an arrangement.

Master bedrooms must ideally be located in the south-west section of the home.

The guest bedroom or children’s bedroom in the north-west — this is

considered a good direction.  

Don’t place the headboard against the window. While windows let in natural light and air, they can interfere with sleep quality.  

Mirrors and doors must not face the bed.

Avoid placement of the bed against sharp wall corners, or directly under a beam.
