We searched a long while for this bed and overall, happy with the purchase! We needed something to hold two adults on the bottom, because we put this in our Airbnb. It's solid and looks amazing. The only thing is, it's hard to change the bedding out on both bunks. Since it's an Airbnb, we change more often. We used a 10" mattress on the bottom and it's fine. It took us about 3.5 hours to put together.
