Overall good support, slight wear after a few months

We bought the lovebed after much displeasure with another popular "order online" mattress. Shipping was swift and unpacking was a lot of fun! Slept great the first night and now a few months later, still sleeping really well. I've noticed that it has a slight dip, very slight, where I sleep. I'm not entirely sure why, as I'm only 150 lbs, but whatever. We rotate the mattress (it sits on our floor) every week so don't know what the scoop is there. So maybe it's not me? Who knows! Anyway, it still is very comfortable, just a little bummed that there's a dip and we've only had it a few months.
