What is the height off the floor of the middle bunk? I'd like to put the bed against a window, but I'm curious how much of the window that middle bed might cover. Thank you!

Hello! The middle bunk bed is approximately 40 inches from the floor.  Let us know if you have any other questions!

Is is an option to build a ladder for the middle bunk that is completely vertical (rather than sloped like in the photos)? Also, I see in some photos the ladder is now there. Does anyone choose to not build the ladder, and if so, how does their kid get into that middle bunk?

Hello.  Unfortunately we cannot make any changes to our manufacturered bunk beds, because they're safety tested as is and so the ladder cannot be modified.  The ladder is removable, so you can take it off when it's not needed but kids will need the ladder to access the middle bunk bed!  Let us know if we can assist you further.

What would the weight limit be (for each bunk)?

Each bed is safety tested to support 400 pounds of rolling weight.  Please let us know if we can answer any other questions!

We just ordered these for our almost 4 year olds. What mattress thickness would you suggest?

Hi there.  Six inch thick mattresses are best for the bunk bed, so that as much guard rail as possible is exposed.  Please let us know if you have any other questions!

How much space is there between each bed?

There is 25 inches from the bottom bunk bed to the second bunk.  There's about 20 inches between the second and third bunks.  Let us know if you have any other questions!

Hello, What is the height of the guard rail?

Hello.  The height of the guard rail is approximately 13 inches.  Let us know if you have any other questions.
