Easy to assemble if you’re used to constructing furniture. Only needed the included hex key for the majority of it and a screwdriver for the slats. I looked at the reviews before purchasing and I believe some of the negative reviews are a result of a random manufacturer board cutting defect or (mostly) user error i.e. not securing the slats or attempting to stand on any wooden beam other than the approved and fully constructed ladder. Good so far, we will see if anything crazy breaks in the first 30 days, but it seems solid and has been supporting me and my spouse for a week now, so I think if it holds both of us then the weight limit should be fairly accurate.
