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 VÅGSTRANDA Pocket spring mattress, medium firm/white, Full package
In Full size, the VÅGSTRANDA mattress ships as one box of 58¾″ × 18¼″ × 17¼″, and it weighs 90 lb 3 oz. The box has no thin edge to grip, only broad, flat sides, and all of that weight sits in one compact block. Lying straight, it needs 58¾″ of boot floor, 18¼″ across it and 17¼″ of height. This is a lift for two people. Stand at opposite ends, hold the box from underneath, and lift together, so the weight never ends up in one person's arms.
