Beautiful solid wood bed. Very sturdy! If you’re using a foam only mattress you may want to buy a slim bunko board to put over the slats as they’re a bit far apart.
We got a hybrid mattress and it’s very comfortable! 
My only complaint is that the holes to mount the steel support beam were drilled on the wrong side of the footboard, so we attached to the headboard first, used a level and had to put new holes on the inside of footboard to attach.
