Walmart offers the Acme Eclipse Twin-Over-Full Futon Bunk Bed in four colors (Blue pictured), model no. 02091W-BK, for $189. Opt for Site-to-Store pickup to avoid the $19.97 shipping charge. That's tied with our mention from last week and the lowest total price we could find by $108. This 78"x41"x65" bunk bed features a metal frame, ladder, guard rails, and more. It accommodates one twin and one full-sized futon mattress.
