In order to better serve the users of wood desks in open-plan offices, the Kano model is used to analyze the problems encountered by users in the office. Combined with quality function deployment (QFD), this study conducted an analysis of the weighted average of users’ needs and the importance of engineering measures of product technical characteristics. The proposed system uses an integrated Kano–QFD model to identify users’ specific needs and scene experience with a more complete service system. Through the hybrid approach of the Kano model and QFD development and design technology, the wood desks in open-plan offices are optimized to improve the rationality and scientific nature of office furniture and enhance its market competitiveness.

The effects of wood knots of Chinese weeping cypress (Cupressus funebris Endl.) wood on selected physical and color properties were investigated. Thirty samples of live knots, dead knots, and clear wood groups were selected for experiments to determine the physical properties of wood density, wood shrinkage, wood swelling, and wood color. The experimental analysis results showed that the wood density values are in the order: dead knots > live knots > clear wood, with a significant difference in wood density between different groups (p < 0.01). In addition, the values of the air-dry volumetric wood shrinkage, air-dry volumetric wood swelling, oven-dry volumetric wood shrinkage, and oven-dry volumetric wood swelling ratios are in the order: dead knots > live knots > clear wood, being consistent with a variation in wood density. Three groups of wood colors were provided: the color of clear wood is light, the color of live knots is reddish, and the color of live knots is blackish, in relative terms. The chromatic aberration between the three groups can be identified, and the wood color difference resulted from the discrepancy in the lightness index.
