@Andrade- I think your concerns are valid.
Synthetic latex is known to out-gas toxic chemicals into the air. The extent to which these chemicals are harmful is still up for debate, but many people report problems related to synthetic latex out-gas exposure.
Symptoms described are headaches, dizziness, heart palpitations, anxiety, difficulty concentrating, and nausea.
If it doesn't put your job in jeopardy, you might look into the safety issue for the patients, as well as the employees.
