Mattress Forum

I purchased a serta icomfort mattress set and have slept on it for three nights now. I have to say its the most comfortable mattress ive ever slept on. All three nights have been wonderfull, however since the first night ive had chest pain around my heart and also some pain in my left shoulder. I believe its respiratory, and that its coming from the chemicals in the mattress off gassing. When i go run the pain around my heart becomes really severe. My question is is this normal? Has anyone else experienced anything similar? Im goin to sleep on the couch for a few nights and try to let this mattress air out (something i neglected to do when i recieved it). Do you think this will help? I really like this mattress and dont want to get rid of it. What do you guys think? Thanks for any advice
