I found it good for the novelty of having bunk beds and then transitioning to two separate twin beds. I had a 6” mattress for the top bunk and a 10.5” mattress for the bottom bunk. I will say if you’re set on always keeping them as bunk beds, go for the beds with the stairs. It’s pricier, but I would have regretted not doing that if the kids didn’t decide they wanted their own separate beds.
