I’ve not slept on a spring bed in a long time so I was pleasantly surprised at how comfortable it is. Surprisingly it works well with my adjustable base.  I sleep hot so compared to a memory foam this mattress has been great and doesn’t hold in the heat. The only reason I’m not giving it a five is because it is super bouncy, so when you move, the entire bed moves also. Could potentially be a negative for co-sleepers. But overall I’m extremely happy with the bed!
