About the BMW 1 Series 2020 boot
The way into the 1 Series boot is low: 22⅞″ of clear height above the loading sill, through an opening 37⅜″ wide, while the boot itself is 26″ tall from its floor. That makes tall boxes a poor fit. The sill is 27½″ high and the floor sits 3⅛″ below it. With the rear seats up the floor is 29½″ long and 40⅛″ wide at its narrowest, and folding them adds 28″, giving 57½″ for long flat packs. If a long box will not go in lying flat, try it standing on its side: at an angle, it then needs less of the 37⅜″ width.
About the KALLAX Shelf unit, white, 43 7/8x57 5/8″ package
Two boxes of equal length make up this KALLAX. One is 56½″ × 16″ × 5″ at 53 lb, the other 56½″ × 16¼″ × 4¾″ at 43 lb 3 oz. Measured along the floor, the boot has to give 56½″ for either box to lie straight. Thin boxes like these offer your hands little to hold, so most of the effort is the weight. Because they share a length, stacking them for one trip is tempting. Resist it: that is 96 lb 3 oz in a single lift. Carry them one at a time.
