As with actual hot dogs and burgers – described by Seletti as "iconic images of American pop culture" – the sofa and chair are each made up of a number of components.
The Hamburger chair features a bun-like seat, with cushions designed to look like a patty, a tomato and a gherkin.
The Hot Dog chair has much the same – but in place of the circular patty cushion is a long sausage embroidered with a squiggly yellow pattern to look like mustard.
Both pieces mark Seletti's first foray into upholstered furniture, which the brand says has come as a response to its "steady growth".
The collection also includes the Tiffany Tree Lamp – Studio Job's resin take on the classic art nouveau design by Louis Comfort Tiffany, which traditionally had a stained-glass shade.
The studio's iconic golden Banana Lamps, originally designed for an exhibition at Belgium's Samuel Vanhoegaerden Gallery, also feature.
All the pieces will be on show at Seletti's stand at the September edition of Maison&Objet, taking place this year from 8 to 12 September.
Studio Job founders Job Smeets and Nynke Tynagel – a former couple – have become known for their autobiographical and maximalist approach to design, and once crafted a coffee table that symbolised their break-up as a head-on collision between two steam trains.
Earlier this year, the duo created a brick punchbag and a smoke-topped table for Gufram's new limited-edition range, which is aimed at the "most demanding collectors".
During last year's Design Miami, they unveiled an eight-metre-tall tree depicting an array of memories and thoughts outside the OMA-designed Faena Forum building.
Studio Job ranked at number 111 on Dezeen Hot List, a data-based power ranking of design and architecture's most influential figures.
