I've only had this bed for a couple of days and so far it's extremely comfortable with no sinking of the mattress. It's neither super firm nor is it soft but it falls somewhere in the middle. My boyfriend also really likes it as well and he usually dislikes any kind of firmness in a mattress. It arrived quickly and was well packaged. The packaging was very hard to take off but I think that having so much packaging was nice that way the mattress had some protection. When I unrolled the mattress there was a ghastly green stain on the one side. It's not huge but was obviously noticeable and that's the only reason that I am not giving this mattress a five star review. It didn't take long to expand and other than the problem with the stain I am extremely pleased with the mattress so far. If you're on a budget and you want a decent bed then I highly suggest this one. 

Pros: Great value and very good quality
Cons: Was stained when it arrived.
