I’m 5’6, 180 pounds, 21 years old. Works for me and my dog. I live in a studio so space is limited and this has given him more room to play and explore. I built it by myself in about 2 hours. Some things to note: the box is heavy as hell. Thankfully my apartment comes with a pulley. I added baby bumper guards to the ladder because it hurt my feet. It is so much better with them. I saw people use pool floaties too. It is a bit wobbly but I am also a bit heavy and I move a lot in my sleep. But so far so good. I removed the side panel as it was hard for me to squeeze myself through. I’m assuming this is more of a kids bed so that is why. I also got this because of how low it is. My ceilings are low. Overall it does the job.
