Spinal Alignment & Pressure Zones for Back Sleepers

What our Austin sleep lab sensors measure when evaluating mattresses for this posture.

14–17 mmHg Low Pressure

Upper Back & Scapula

Quilted pillow-tops or buoyant latex relieve tension around the shoulder blades while preventing the upper torso from rounding forward.

16–19 mmHg Supported

Lumbar Spine (Lower Back)

Reinforced center-third zoned coils push lightly into the small of your back to maintain the natural lordotic curve overnight.

19–22 mmHg Neutral

Sacrum & Glutes

Firm high-density transition layers keep the heavier pelvic girdle aligned on the same horizontal plane as your ribcage.

Sleep Coach Setup Checklist

✓ Look for center-zoned pocketed coils or high-resilience latex cores that keep your lower back from sinking after 4+ hours.
✓ Use a medium-loft pillow (3.5–4.5 inches) so your chin stays neutral rather than tucked toward your chest.
✓ If you wake up stiff in the morning, slide a thin bolster pillow beneath your knees to unload lumbar facet joints.
