Nice good looking loft bed. The bed feels sturdy but does wobble once my son (4 yrs old) moves around while on top.  There seems to be a large gap from the twin mattress and the end of the bed.  See the photos. Purchased a 9” twin mattress. So not sure if the mattress is too short or if the bed it too long. 
The color is nice (gray) but it will be hard to find a marker to cover nicks  in the wood.
The skirt at the bottom is only 2 sided.  And within 2 weeks of affixing it to the bed, it started falling down. 
Can’t comment on the assembly because I hired someone to assemble.
