A cushion is placed between the seats which would allow the Queen to lie down. On the left, a flap was raised which opened up a connecting boot, sometimes used to house mail. This added to some extra space beyond the confines of the carriage so that Adelaide could lie comfortably with her feet projecting into the boot. The saloon was built by the London and Birmingham Railway.
