Four hundred and ten pounds is the total rating on this unit, far above the usual figure for a narrow bookcase, and it comes from thick boards through a 19.5 x 9.5 in carcase rather than a metal frame. Ten open cubes 8 in high and 9 in wide climb 71 in, with a drawer 16 x 7.5 x 3.5 in inside at the base for items that should not be on show. The bookcase weighs 55 lbs in white engineered wood and MDF. The narrow depth suits a hallway or the space beside a wardrobe.
