The Dag Daybed was designed by Teresa Lundmark and Gustav Winsth for Gärsnäs, the Swedish furniture manufacturer whose factory has been working in solid timber in Österlen since 1893. The piece starts from a specific problem with modern daybeds: most have become glorified benches, prioritizing profile over comfort. Lundmark and Winsth used comfort as the primary design directive throughout the project.

The construction is solid beech, a material Gärsnäs has worked in for decades and that the factory's craftsmanship is particularly suited to. The frame is stripped back and structurally direct, with the padding doing the expressive work: the cushioning is allowed to swell into and out of the cavities in the wooden frame rather than sitting flush against it. The contrast between the precise geometry of the beech structure and the soft, protruding upholstery is the piece's defining formal quality, each element making the other more legible.

The daybed is designed for both private and social environments, with proportions and comfort levels calibrated for casual seating rather than formal use. Gärsnäs's experience in wooden joinery gave the designers the opportunity to develop a construction that is detailed without being complicated, keeping the visual logic simple while the making is precise.
