Foam and Mattresses

…The good news

A mattress constructed of foam can provide excellent value in permitting or enabling a good ‘quality sleep’.

 

But all foams are not the same....

  • The Importance of Density - density is the key indicator of foam’s performance in regards to comfort, support and durability. The denser the foam or the more material used to produce it, the more material there is in the mattress providing support for body weight.
  • Firmness and Support – Firmness is an indicator of a foams ability to allow a weight to “sink in”. Support is the foam's ability to "push back" against weight and prevent the foam from "bottoming out". Higher density foam helps prevent the feeling of having the foam collapse beneath body weight. Both firmness and support affect foam comfort.
  • Durability of Foam - Density also translates into foam durability. Higher density foams better retain their ability to provide support.

Foams can be ‘married’ with other materials or components in a mattress Some foams are more environmentally responsible than others.

 

…The bad news

  • Foams without a contaminant barrier will absorb body fluids and odours
  • With use, foams...some more quickly than others...do not retain their shape
  • Foams are insulators and therefore do get warmer when being slept upon
  • As foams change temperature their firmness changes
  • Some foams have a ‘manufacturing’ odour
  • And some foams can result in allergic reactions
