Distance from bottom bunk slats to top bunk /34.5 inches
Distance from top bunk slats to top of rails / 13.75 inches
Distance from floor to bottom rail of bunk / 10.5 inches
Time to build with 2 people / 2.5/3 hours
I did have some parts damaged during shipping, so I have submitted a claim on the and website for replacement parts. Some things to note / I did not realize if these twins were set up as 2 twins, one of the beds would be mini / the top bunk is much smaller. I had planned to buy 8 inch mattresses / in real life, the distances from bottom to top bunk and from top bunk to railing seem much smaller. I decided on a 6 inch mattress instead. I like that these bunks are low profile. I will update my review if I dont receive the replacement parts or if it seems less sturdy once my mattresses have arrived, but as of now, I am happy with my purchase. Best quality product
6 inch mattress seem best for the bunks
