the science of spinal support
Density, rebound layers, and spring calibration directly influence how your spine recovers overnight.
Why mattress engineering matters
Your spine carries the weight of every decision your body made today. The right mattress is the difference between waking refreshed and waking with stiffness that follows you into the workday.
Modern orthopedic mattresses are engineered in measurable layers — high density base foam, calibrated spring systems, and breathable comfort layers that work together to neutralise pressure points.
The role of density
Density (measured in kg/m³) determines how well a mattress resists compression over years of nightly use. A density below 30 collapses quickly; the 45–55 range used in our Concord and Rebound lines preserves shape and support far longer.
Higher density does not mean a harder mattress — it means a mattress that keeps doing its job after the first few months.
Spring calibration
Bonnell, pocket, and continuous spring systems each have a place. The 8.8 spring system used in our Concord 30 was selected for the broadest body-type support range, distributing weight evenly across hips and shoulders.
What this means for you
If you wake with lower back stiffness more than three mornings a week, your mattress is likely the cause. Our consultants offer free posture assessments at every showroom — bring your sleep complaint and we’ll match you with the correct firmness profile.
