We build it well and added some silicone caulking to the joints and bolted areas as well as the slats . on top of the slats we placed a thin wooden board 1/4 thick to prevent wierd pressure point or damage to mattress. We used a foam/gel hybrid mattress 8 thick. We added pipe insulation to the ladder to pad the foot. Our cube shelf fits well underneath with a twin bed. 75lb kid on top and it doesnt squeak or shake. Good,
Almost a year and still nice
