About Khoy 沙发床

Khoy是一款专为空间有限的住宅设计的沙发床。它采用经过测试的双层泡棉床垫，可由沙发轻松转换为标准双人床。沙发状态下，坐面为150毫米中等硬度的支撑型泡棉层；床铺状态下，40毫米的记忆棉层则形成更为柔软、贴合人体的睡眠表面。模块化靠背可自由移动、拆卸，亦可用作扶手，且每次模式切换均无需任何工具。面料采用再生聚酯纤维制成，可拆卸并可机洗。泡棉部件经真空压缩处理，便于扁平化包装运输。

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.
