Walmart offers the Acme Eclipse Twin Over Full Metal Bunk Bed in Black, model no. 02053BK, for $129. Opt for in-store pickup to avoid the $19.97 freight shipping charge. That's $30 under our mention from last October, the best price we've seen for this bed, and the lowest price we could find today by $62. (For further comparison, most retailers sell it for $299 and up.) This 78" x 54" x 60" bunk bed features a metal tube supports, ladder, and guard rails. It accommodates one twin and one full-sized mattress.
