Two children with a significant age gap have different sleeping needs — the older child needs more space while the younger child needs a safer, lower sleeping position. A standard bunk bed with two identical single tiers does not account for this difference. A bunk bed with a double bed on the lower tier gives the older or larger child a full-width sleeping surface below, while the younger child occupies the upper single. The DHS double and single bunk bed addresses exactly this arrangement within a 200×146.5×150cm solid pine frame, available in white and grey.
