I was a skeptic since the price was so low & I wasn't going to be able to feel how comfortable this mattress was before I bought it. But I'm so glad i did. I recently got a rescue dog & I was sleeping in a twin size bed (with a boxer/English Bulldog) so naturally I bought a new bedroom set & started searching for mattresses. The day it got here (3 days early), it filled out completely before the end of the day & it had NO smell to it at all! This matress is SO comfortable. My back doesn't even hurt anymore during the day which is awesome. This mattress is absolutely worth getting, don't let the price throw you off from getting it.
