Qualisys 3D optical motion capture system tracking 18 reflective markers placed along the spinous processes from C7 to S2 during simulated sleep postures.
Ergonomists placed 3D reflective optical markers along the spines of 32 healthy adults to measure real-time vertebral curvature on pocket coil hybrids versus 100% natural latex mattresses.
Accommodates pelvic mass while preserving horizontal spinal axis without lateral tilting.
Causes severe sagging at the hips, creating compensatory lumbar lordotic hyperextension.
Both systems successfully maintained neutral spinal alignment within safe limits, with pocket coil hybrids demonstrating 14% higher lumbar upward pushback and latex demonstrating 22% better pelvic torsion dampening.
Both pocketed coil hybrids and natural latex are tier-1 orthopedic surfaces. If you want a buoyant, traditional feel with targeted lower-back pushback, choose pocket coils; if you want silent contouring with zero pressure points, choose natural latex.
Recommended Firmness Target: 6.0 to 6.5 out of 10
Choose hybrid mattresses that combine pocketed steel coils with a natural latex comfort layer for the best of both biomechanical worlds.
