Pillow Guide by Sleeping Position
How pillow loft and support interact with mattress feel and sleeping position.
Pillow and mattress work together
The amount your body sinks into the mattress changes the distance your pillow needs to fill between head, neck and sleep surface. That is why a pillow cannot be selected in isolation from mattress feel.
Side sleepers
Side sleepers often need enough loft to bridge the shoulder-to-head distance, though a deeply contouring mattress may reduce the required height.
Back and stomach sleepers
Back sleepers often prefer moderate loft, while stomach sleepers commonly need less. Personal anatomy and mattress sink can shift those starting points.
