Pillow Loft (Height) Guide by Sleeping Position
Side Sleeper
High Loft (5" – 7")
Fills the deep gap between ear and outer shoulder to keep cervical spine parallel to the mattress.
Back Sleeper
Medium Loft (4" – 5")
Supports the natural C-curve of the neck without angling the chin too close to the chest.
Stomach Sleeper
Low Loft (2" – 3" or No Pillow)
Prevents unnatural backward hyperextension of the neck; flatter is better for spinal health.
