Walmart offers the Acme Eclipse Twin-over-Full Futon Bunk Bed in four colors (Blue pictured), model no. 02091W, for $179.88. Opt for in-store pickup to avoid the $19.97 freight shipping charge. That's the lowest price we could find by $48, although we saw it for a buck less last August. This 78" x 41" x 65" bunk bed features a metal frame, ladder, and guard rails. It accommodates one twin and one full-sized futon mattress and has a total weight capacity of 350 lbs.
