House-shaped twin bed frame with a roof outline creates a defined sleep space kids can decorate while fitting a standard twin mattress on the 76 x 39.5 in platform. Solid pine wood paired with plywood and engineered wood slats forms a supportive base with a 200-lb capacity for the daybed, so no box spring is needed. The 81.5 x 42 x 66.5 in frame integrates 11-in guardrails that help keep the mattress stable. A pull-out trundle on smooth wheels adds a 75.5 x 40.5 x 11 in extra sleeping surface with stoppers that control travel and keep it from rolling too far under the bed.
