You can use it as queen bunk beds or two separate queen beds. If it is a bunk bed there are 4 supports in the bottom bunk and one support in the middle bottom bunk. The top bunk has 4 leg supports. If you take the top bunk off and use it freestanding separately, there is an extra support leg to go in middle bottom. There are metal slatstubes to support a mattress. It doesn’t need a plywood base or box springs.  Teen boys think it’s comfortable. It is a tad shakey. If there were kids roughhousing on it I’d want it bolted to the wall. In everyday use I’m comfortable with it not being bolted to the wall. It has somewhat a “barn” look with the rustic wood, but seems to go with a neutral decor.  The ladder to go up is hard on the feet but it gets you to where you are going.
