I have had the bed for about four months now. If bigger people are on the top bunk, it will squeak a lot when they are moving. If the bigger people are on the bottom and the smaller on top, its doable. Still squeaks, but not as bad. I have not tried tightening the bolts yet but I am sure that would help along with some squirts of wd/40. I am happy with the purchase because it gives us so much more sleeping space as well as floor space underneath the bed. Just what I needed!!
Be gentle with the bed and you should be fine.
