Hi bw1985,
The Arctic Dreams uses a high performance polyfoam in the comfort layer and doesn’t contain any memory foam.
While most new mattresses have an initial odor that will generally dissipate within a few days (although some people that have a more sensitive sense of smell may notice it for a little longer) … all the materials in their mattresses are CertiPUR-US certified (see post #3 here) which means that they have been tested for any harmful substances or VOC’s so they would certainly be a “safe enough” choice.
