The mattress is very heavy seems sturdy it comes in a big box, I honestly thought it was going to be a memory foam type of mattress rolled up in a box, I was wrong. So far weve had it for 2 to 3 weeks and mattress is firm but not brick hard, we have been able to get a good rest in comparison to our old mattress we were having back aches, keeping our fingers crossed hoping this mattress turns out to be the one and only for years to come
