Question: Is the ladder structurally required or can it be left out? There will be no top bunk usage by anything but the cat.
Document: I ordered these to fit in a small guest room for extra sleeping space. I assembled them myself (one 60 year old woman) in a couple of hours with just a few mis-steps from the picture-only instructions from China. Not quite as heavy duty as I had hoped. When a full-size adult climbed the ladder to the top bunk, the bed felt as though it might try to pull over, but it did not lift off the ground.
The good news is that if you ever disassemble the unit to move it to another location, complete disassembly is not required. You could probably disassemble it, move it to another room, and re-assemble it within a half-hour or so.Note that the top bunk has guard rails, but the manual says your mattress on that bunk should be maximum 6&#34; thick.The physical appearance of the unit is fine. The packaging included foam and cardboard to prevent scratching during shipping.
Shipped quickly, easy to put together. Very useful. Only thing I didn'tlike is the deliveryy driver left the huge box leaning against my house in my driveway - not even by my door. He didn't knock or anything. Good thing I was home
Read the instructions and don't do anything half-arsed. Also, if this is going to your college kid's apartment or you are a college kid yourself, don't invite your girlfriend/boyfriend to &#34;spend the night.&#34; It will not be able to handle much stress and jostling. At least I wouldn't risk it. If this was a twin top/bottom or had a couple more supports, then I'd say don't worry about it.
This bed supports me well and is very sturdy. The building was easy, just listen to the instructions. Shipping was fast considering the big 100 pound box. All is well except the little legs supporting everything, I suggest you put this bunk bed against a corner and use a store pool noodle to cushion the ladder.
my girls love the bunk bed but the stairs to the top bunk are very steep and they have fell once or twice trying to get off and on.
This bunk bed it very shaky and cheap and hurts my kids feet when they use the bars to climb up to the top bunk. (and i tested it out and it hurt my feet too)
Great price and pretty sturdy, it is a bit squeaky, not easy to sneak out of it after the kids fall asleep. Kids love the top bunk to get away from the dog if they have something he wants.
We got this bunk bed for our three boys(ages 9, 6, 4) to share and it has been perfect for them. The oldest sleeps up on top, while the younger two share the bottom. It was fairly easy to put together, I did it with only one person.
Top bunk is MAX 225 lb with bed and the bottom bunk(where i sleep) is 300lb.It fits me well since i rent my own place and go to school as well.PS:It did come missing a part but as the manual say either call or order online.
Answer: If nothing is going on top, then yes, it could be left off.  It's held on by L hinges on top and screwed to the bottom bunk, both sides.
