Acacia and rubber wood give the tall headboard on this full size bed frame with headboard a rustic golden brown grain, and it rises 13 in above the platform as a backdrop for bedtime reading. Twelve plywood slats and three middle support legs with adjustable foot pads carry 660 lbs, so no box spring needed. Recommended mattress thickness is 4 to 8 in, and an embedded platform keeps the mattress from sliding or sagging. Under the frame, 9 in of height lets a sweeper pass through or holds flat storage boxes. The frame measures 77 x 57 x 41 in with a 75 x 54 in bed surface and weighs 55 lbs. Plywood, acacia wood, rubber wood and MDF make up the build. It works well in a primary bedroom, guest room or teen room, and assembly is needed.
