Although it arrived with the box broken sitting on the side of the steps, I assume since it was snowing outside maybe that had something to do with it but good thing the box was heavy so know one could steal it. I hate FedEx! Anyway the mattress is , to my surprise, everything I needed. It’s innersprings are firm yet soft and bouncy. Not sure about durability, yet. I’m waiting on my bed frame but I did test it out and it’s a great mattress for the 180 bucks I paid for it
