We have only been sleeping on this for a little over a week now. This is a very soft foam . Very comfortable. 
I bought this because our mattress was just not comfortable anymore so I thought to try this. So far it has made it a little better but not amazing like some people . I notice that I sink in to the foam quite a bit and it makes it hard for someone like myself who moves around a lot in her sleep to stay asleep because it’s can be hard to get yourself out of the sinking foam once it fits your body curve. Maybe not the best for someone who doesn’t sleep in one position.
I probably just need to invest in a new mattress. 
Anyway, this is very comfy, and soft. So I’m keeping it. 
Hopefully I’ll fall in love the longer I sleep on it.
