The Variocage Double (Dog, Lockable) measures 103 cm in length, 93 cm in width, and 65 cm in height. The Mercedes-Benz GLE boot floor length with rear seats upright is approximately 105 cm, and the vertical height of the boot opening is about 81.3 cm, with a width that comfortably exceeds 93 cm. Given these dimensions, the carrier should fit in the back trunk of a Mercedes GLE with the rear seats upright, as the boot length and height accommodate the carrier's size. The width of the boot is also sufficient to fit the 93 cm width of the carrier.
