It's not for everyone since people have preferences about firmness, pillow top etc. I'm still testing it out since I've only had it for a few weeks. Initially my back was worse for at least 3-4 days. In the last week it feels improved.
I ordered the mattress it was at my door the next day! No store, no haggling, it took me less than 5 minutes start to finish to order and inbox and setup. Daughter loves the mattress.
