Beautiful modern bunk beds perfect for small spaces. Definitely recommend a 6-inch mattress for the top. I used a 10-inch mattress in the bottom and that worked really well. Super sturdy. I can climb up to the top bunk with my kids and feel safe.  Just be prepared to spend a couple of hours assembling this bed since there are a lot of parts! Assembly goes way faster with two people and a drill but not impossible for one handy person.
