About Khoy Sofa n'Igitanda Bivanze

Khoy ni sofa ihinduka igitanda yagenewe amazu afite umwanya muto. Khoy ihinduka iva kuri sofa ikaba igitanda cyuzuye ikoresheje matora y'ubwoko bubiri bwa fomu yageragejwe. Mu buryo bwa sofa, aho wicara ni urwego rwa fomu rukomeye buringaniye rufite milimetero 150. Mu buryo bw'igitanda, urwego rwa fomu ya memory ya milimetero 40 rukora aho kuryama horoshye hihuza n'umubiri. Umugongo w'ibice bishobora kwimurwa, gukurwaho cyangwa gukoreshwa nk'aho gushyira amaboko, kandi buri guhindura uburyo ntibisaba ibikoresho. Ibipfuko bikozwe muri polyester yongeye gukoreshwa kandi bishobora gukurwaho no kumesa mu cyuma. Ibice bya fomu bikandamizwa hakoreshejwe umwuka kugira ngo byoherezwe mu bipaki byoroshye.

Unique Properties: This sofa bed is a two-in-one furniture solution developed to address contemporary requirements for comfort, space efficiency, and adaptability. It converts from a sofa into a full-quality bed using a tested dual-foam mattress system that ensures consistent support in both configurations. In sofa mode, the seating surface is formed by a support foam layer providing medium-firm comfort. When transformed into a bed, a 4 cm memory foam layer becomes the sleeping surface, offering a softer feel that adapts to the body for improved sleeping comfort. Modular components, vacuum-packed delivery, and removable, washable covers contribute to flexibility, durability, and a user-oriented design approach.
Dimensions & Packaging: Sofa mode dimensions: W 2000 mm × D 900 mm × H 420 mm (seat height). Bed mode dimensions: W 1800 mm × D 2000 mm. Mattress construction: dual-layer foam system with 150 mm medium-firm base foam and 40 mm memory foam comfort layer. Upholstery: 100% recycled polyester, removable and machine washable at 30 °C. Foam elements vacuum-compressed for compact flat-pack shipping.

Production Technology: The design was developed through iterative prototyping and ergonomic testing, with a strong focus on material performance and modular construction. A dual-density foam system was selected based on compression, resilience, and lifecycle tests to ensure long-term comfort. The structure is optimized for vacuum compression and flat-pack logistics, while removable textile covers support maintenance, repairability, and extended product lifespan.
Design Challenge: The hardest part was designing a sofa bed that combines high-end elegance with broad home compatibility while being produced entirely in Europe. We had to simplify every manufacturing step, remove costly elements, and create a neutral yet premium product that stands out in its category, balancing quality, aesthetics, and efficient European production constraints.
Research: Type of Research: Applied design research for a commercial multifunctional product. Objectives: Enhance comfort, adaptability, modularity, and sustainability. Methodology: Iterative prototyping, material and ergonomic testing. Data & Tools: User surveys, interviews, observation, 3D modeling, foam testing. Participants/Experiments: Early users, small-scale home trials. Results: Optimized mattress layers, modular system, compact shipping. Insights/Impacts: Showed how modular design improves usability and environmental performance. Real-Life Effects: Supports modern living, reduces shipping footprint, informs sustainable furniture design and e-commerce strategies.
Inspiration: The project was inspired by everyday living situations where limited space conflicts with the need for genuine comfort. The motivation was to replace compromise-driven sofa beds with a solution offering true bed-quality sleep. Research focused on ergonomics, foam performance, modular systems, and logistics efficiency, resulting in a design shaped equally by user behavior, material testing, and contemporary living patterns.
Project Duration: The project was initiated in 2023 and developed between 2023 and 2025 in Hungary and Helsinki. The product exists as a fully realized item and has been sold as part of our e-commerce brand for the past two years. During development, a full-scale prototype was created to refine the design and production process.
Operation Flow: The sofa transforms easily between sofa, bed, and day-bed by rearranging its cushions and frame. Users lift or slide elements without tools, guided by intuitive positions. The modular backrest can be moved, removed, or used as armrests. This simple, playful interaction ensures comfort in every mode, quick setup, and adaptability to different spaces, while maintaining the product’s high-quality feel and ergonomic performance.
