Two years ago, we paid $3000 for a Sleep Number Bed. After about a year, it was emitting a strong chemical smell, which has become worse over time.in the FAQ section of the manual, it says this can happen and the remedy is to place dryer sheets on the air chamber. I've done that, dismantle and air out all the components frequently and have resorted to putting multiple extra layers of bedding over the mattress to keep the smell from coming up. The smell permeates everything including my hair and bedclothes. I have headaches, and rashes and feel this toxic smell is ruining my health. Sleep Number customer service says the bed just passed warranty and won't help. I'm concerned these chemicals could cause cancer, and the smell is overwhelming!
