Its sturdy! Each bunk isnt very high, which works for kids but I wouldnt recommend it for teens since they wont be able to sit up in bed.
I love that the bunks each come apart to be their own separate bed, which if you plan for the future is great.
The bunks are pieced together on top of each other with a metal rod, if you were wondering.
Ive seen the complaints concerning the stickers. After putting together this bed, I dont see why you would complain about the stickers since all they do is label each piece Im glad for them. They come off very easily if you have any trouble you can simply use a razor.
The bed was simple enough to piece together, the instructions were clear, nothing was confusing for us, all the pre drills were in the right spot. The time it took us to put it together was about 4 hours, mind you we had numerous breaks and interruptions.
