Oneseater

Oneseater, or one-seater, is a term used to describe seating or vehicles designed to accommodate a single person. In furniture, a one-seater denotes chairs, armchairs, and compact sofas intended for individual use. Such pieces prioritize compact footprints and ergonomic support, with padding, backrest contouring, and seat depth chosen to suit a single occupant. Materials vary from wood and metal to leather or fabric upholstery and finishes, and designs range from minimalist to decorative. One-seater furniture is common in small living spaces, offices, and public waiting areas where efficient space use is important.

In transportation and vehicle design, a one-seater refers to a cockpit, saddle, or cabin intended for one occupant. This includes single-seat motorcycles, racing cars, and certain aircraft designed for solo operation. In aviation and motorsport, single-seat configurations emphasize pilot or rider visibility, control placement, entertainment or instrumentation within reach, and rapid egress in emergencies.

Historically, the idea predates modern manufacturing and appears in simple chairs and stools through to specialized competition vehicles. In contemporary markets, one-seater products are produced by various manufacturers as space-saving options or performance-focused designs, often marketed on ergonomics, compactness, or sportiness.
