This bed is solid. Spent an afternoon and into the evening putting it together with help from the hubby for the heavy lifting bits. You need lots of floor space as the beds will be put together completely before stacking them. I would suggest getting a better allen wrench to work with since the one that comes with the hardware would not have been able to easily do the job, it is quite small. The directions are just pictures so really pay attention to the details. Overall, great beds so far.
