The price of a theatre bed (multimedia/smart bed) is primarily driven by its integrated technology and material quality. Key factors include the built-in projector system resolution (720p vs 1080p/4K), the motorized retractable screen mechanism, and the integrated surround sound audio system. Additionally, high-end models feature massage functions, adjustable headrests, and USB/wireless charging ports. Buyers should verify the frame material (solid wood vs. MDF) and the upholstery grade (genuine leather vs. high-quality PU), as these significantly impact the long-term durability and the final wholesale quote.
