How do I choose loft height for my sleeping position?
Side sleepers usually need a higher loft to fill the shoulder gap, while back sleepers often do better with a medium loft. Stomach sleepers generally prefer a low, softer profile.
How firm should memory foam feel?
Firmness is a matter of personal feel. Look for reviews that describe how the foam responds to pressure in your usual position, not just a single firmness word.
Is a firmer pillow always more supportive?
Not necessarily. A pillow that is too firm can push the head upward, so the right balance depends on your position and body shape.
