🛏️ 寝台 = 寝 (sleep) + 台 (platform, stand): a platform for sleeping
寝 means sleep and 台 means stand or platform, so 寝台 is a raised platform you sleep on, which is a bed.
台 — mouth 口 + 厶 (private)
Originally depicted a raised platform or terrace, suggesting elevation and a place to stand. The character later extended to mean stage, podium, or station. In modern usage it also serves as the simplified form of 臺 (platform) and 颱 (typhoon), and names Taiwan (台灣).
