Only 4 weeks in, but very pleased with unit stability, I'm 185 Lbs. I didn't even secure it to a wall with the optional hardware in the box.
Also loving the fact that I can use magnets almost anywhere on the frame to mount or hold items!
*Climbing up is a bit awkward for me, but a chair at the ladder base helps a lot.
** Notice: I received the bed in two boxes; the 2nd box arrived one day after the 1st, but I was not informed of that fact...so I had to wonder if the other half of the bed was on it's way for a day. : ,)
