Hi Lroth1986,
All foam materials including latex have “some” offgassing but all the latex you are likely to encounter (whether it uses natural or synthetic rubber or a blend of both or is made with the Talalay or Dunlop process) has been tested for harmful substances and VOC’s by testing organizations such as Oeko-Tex or Eco-Institut and I would consider any form of latex foam to be “safe” (see post #2 here).
