General information
Mattress for distribution
For hospital bed mattress, see item code XMEQBEDSH1M
Foam density is one of the factors determining the quality. Low grades range from 18 to 22kg/m³; medium grades from 22 to 27 kg/m³, while higher grades are above 27kg/m³.
The minimum foam density for a bed mattress is 22kg/m³.
Unit conversion: pound per cubic foot to kilogram per cubic meter: 1lb/cuft = 16kg/m³
The standard quality of foam is open cell foam. Higher quality mattresses are made from closed cell foam.
The factor determining the firmness of the mattress is the Indentation Load Deflection (ILD). The higher the number, the firmer the mattress. This factor varies from 5 to 100 kg. The ILD value for a specific type of foam is also correlated to the thickness: the thicker the mattress, the higher the ILD value.
Sag factor gives an indication of cushioning quality. A high value indicates a resistance to “bottoming out”.
Air flow measures the capacity of the foam to evacuate moisture.
Impact Resilience is a measure of elasticity, bounce, or springiness of the foam.
Some specifications may vary with national standards and local market conditions. For locally sourced items, check the relevant national standards or specifications. Any important variation from the below standard specifications needs to be approved by your technical department.
