Strength, style and substance are the foundations for the pride we feel in the Hillsdale Kids and Teens Twin Over Twin Caspian Bunk Bed with Hanging Nightstand in Gray. Hillsdale Kids and Teen has been designing bunks for the past 8 years under the brand NE Kids. Traditionally, we sell bunk configurations that demand higher retail price points. As we embarked on the design process to create this affordable bunk, we took the time to think through the lessons we have learned from developing our more expensive bunks and studied ways we could apply them to achieve Value, Quality, Strength, Comfort and Safety at this incredible price. We are confident that these details will help you feel secure that you have made the right decision first for your child’s safety and second, for your child’s own unique style.Features : Third party certified to meet all ASTM applicable safety standards.; This bunk has a plywood slat roll foundation and does not require an additional foundation of any kind.; By design all 13 slats are properly spaced to ensure the safety of your child.; The distance from the top of the lower bed slats to the bottom of the slats of the upper bed is 38”.; Accommodates an 8” mattress on the top bunk.
