The bunk beds are wonderful. I would definitely recommend them for those who are talented at assembly, or even for less talented (like us) who allow a lot of time.  I had read 2-4 hours for assembly, and those folks are VERY talented.  It took us about 10 hours.

The reason for 4 stars instead of 5 was because it took my husband and I a significant amount of time to put them together, part of which was because we lost a barrel bolt and had to go to the hardware store to get a replacement.  

The manufacturer might consider enclosing some extras of the hardware.  Another possible suggestion would be putting the hardware in separate bags, pouches, or whatever container so that idiots like myself can open the containers separately without dropping the pieces.

We did get it put together, it looks great and looks like it will last my granddaughters for years.
