Armchair Cruisers builds its recliners and loveseats on a purpose-made chassis, not a sofa strapped to a go-kart frame, and drives the whole thing with a single joystick. Buyers choose gas or electric power, with the maker’s own site posing the top speed as a rhetorical “is 40 mph fast enough?” The electric loveseat model starts at $5,450; single-seat chairs run cheaper, from $3,495.
