Materials that matter

1.    Springs and coil counts: More, finer coils = steadier contour and better edge hold.

2.    Foams and densities: Denser foam lasts longer and supports better.

3.    Natural fibres: Wool, cotton, and bamboo help wick moisture and balance heat.

4.    Cooling gels and airflow: Channels and gels move heat away from the body.

5.    Hypoallergenic layers: Reduce dust and odours; pair with a washable cover.

Comfort tech. What to look for

1.    Zonal support: Extra lift under hips; softer zones at shoulders.

2.    Pressure relief: Plush top layers that ease joints.

3.    Edge support: Reinforced sides so you can use the whole surface.

4.    Motion isolation: Keep partner movement to a minimum.

5.    Temperature regulation: Breathable covers, vented sides, or open-cell foams.

Health and posture

1.    Spinal alignment: Hips and shoulders should sit level.

2.    Back pain support: Firmer cores help; add a softer top for comfort.

3.    Shoulder and hip relief: Softer surfaces reduce numb arms and sore hips.

4.    Allergy-friendly choices: Choose low-VOC foams and washable covers.
