i love this mattress. anything is better than the mattress i was sleeping on before but this is absolutely perfect. no bad smell when i unraveled it. this mattress is the perfect balance of firmsoft for me. i like firm but i don’t like feeling springs so the added cushion on top of the mattress is perfect. i sleep very well on it. i also didn’t wait the full 48 hours for it to go back to its original shape and instead waited 10 hours. i think if you are very excited like me you don’t need to wait the 48 hours ) it was still perfect and didn’t quite reach the 12 width but reached 11 which is no big deal to me.
