So far so good. It feels more like a firm but it still feels good to me. Some odder but so slight I hardly even noticed. Took a few days and the odder was gone. I got a mattress cover with the frame I bought, which works great, and I would recommend putting it on as soon as the mattress comes out of the box. My mattress expended rather quickly and made it a little tougher to get the cover on. I may, in the future,  get  one of these for my son and daughter.  

No signs of damage on either the boxes or either of the products. For the price, for me, it's a great deal.
