Luxury automakers like to crow about their flagship models boasting first-class cabins, but the truly elite class of travelers know there’s a class above that. We’re talking about private jets, and now Mercedes is applying its skills to those as well.

Mercedes design department has collaborated with Lufthansa to create a cabin space for executive jets that looks even more upscale. Mercedes-Benz Style (Merc’s design consultancy for non-car projects) and Lufthansa Technik (Lufthansa’s aircraft services biz) have created a new concept for private jet interiors that eliminates the usual linear separation of ceiling, wall, and floor in favor of a “dynamic, spiral layout.”

The concept integrates the walls, ceiling, and floor of the cabin into one fluid, continuous surface, with the furniture similarly integrated into the design with chairs, sofas, beds, and tables. It’s even got a fish tank on board and auto-dimming touchscreen glass panels in front of the windows that can control the infotainment system.

The design is being showcased by Mercedes-Benz Style and Lufthansa Technik at the European Business Aviation Convention and Exhibit (EBACE) in Geneva. It’s the same show where Brabus displayed its jet cabin design, rival BMW Designworks did the same, and where the Mercedes’ Eurocopter cabin design debuted four years ago. There, Mercedes hopes to attract orders from private customers. If the finished product ends up half as stunning as these design renderings look, we don’t doubt they’ll find a few takers.

The luxurious and innovative airline cabins will be specifically made for the Airbus A320 and the Boeing 737 range.

“It was an inspiring challenge to transfer our design philosophy of sensual purity into the area of aeronautical engineering. The spectacular architecture of the interior shows creativity and modernity. Sensual surfaces and clear forms, combined with intelligent high-tech features and perfectly shaped modern luxury are the characteristic features of Mercedes-Benz design,” Gorden Wagener, Vice President Design, Daimler AG, said.

“The purpose of our cooperation with Mercedes-Benz Style is to unite the two companies’ innovative expertise in the areas of design and technology. Our goal is to offer a highly discerning global clientele a standard of interior design that leaves nothing to be desired. Whether for private or business use, our modular completion concept perfectly fits every purpose,” Walter Heerdt, Senior Vice President VIP & Executive Jet Solutions, Lufthansa Technik AG, added.

Over the coming months, Mercedes-Benz and Lufthansa Technik will further work upon the design of the cabins and analyse the potential demand for their product in the market.
