Super sturdy bed!  I was looking for a bed that could hand my weight (225lbs) along with my son's (40lbs) and this bed did not disappoint! The espresso finish seems to be good quality and the bed itself is well made.  I used a Wayfair memory foam twin mattress and it's quite comfortable (the slats are close enough to not be felt). 

My only complaints are: 
- When screwing in the bed slats, the very end slats (#15) caused the bed rails to split as there are no pre-drilled holes.
- The ladder does not screw into the bed frame on the upper outside, so it pulls away under my weight.

Overall great buy for the price!
