We purchased this bunk bed for my 2 year old and my 9 year old. The 2 year old is on the bottom and she loves all the space. The top bunk is sturdy and I feel safe having my 9 year old up there. My husband put together the bunk beds in about 3 hours, he did it by himself and said it was pretty easy to follow the instructions and Get it built. Again, it’s sturdy and I feel safe having my kids on it!
