Terrible off-gassing odor
"The mattress itself might be fine, but the initial smell is absolutely awful. The chemical off-gassing is so potent that it triggered immediate irritation in my nose and eyes while I was trying to set it up. It has a very harsh, toxic-like smell that makes the entire bedroom unusable without opening all the windows and running fans at full speed. For the price, this level of chemical fumes is highly disappointing. Buyers beware: you will need a separate, heavily ventilated space to air this thing out for days before you can even think about sleeping on it."
