It's a perfect bed for a tight space! It's great for guests because of the trundle. I will say that a 7" mattress is the highest you should go for these. Assembly can be easily done with one person. Also, DO take it out of the box if you're transporting it up stairs. The parts are by far lighter and takes less time than trying to haul the box up stairs. We tried taking it up stairs with three people and it was ridiculously difficult. As soon as we opened up the box, it took us less than five minutes to get all the parts up four flights.
