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 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.
6 inch mattress seem best for the bunks
