From Montana Woodworks, this uniquely designed and purposefully useful twin bunk bed over full futon employs the best of both items and is combined with the ingenuity of our master craftsmen. The twin sized upper bunk bed is designed for use with a maximum mattress height of 8" and features three side rails for superior safety. Built in ladders at both ends increase ease of access to the upper bunk while the full sized futon below features a plush mattress for comfort and relaxation. Steel hinges and steel futon frame provide years of trouble-free use. Handcrafted in Montana, USA, using genuine lodge pole pine! Twin sized bunk bed mattress not included.
