What part of speech is “bed”

bed is a noun that means a piece of furniture used for sleeping and resting.

for singular usage, be sure to use 'bed' and not 'beds'. It is also proper to use 'bed' for any type of furniture used for sleeping, including futons, couches, and air mattresses. Additionally, always follow 'bed' with an article (i.e. 'a bed' or 'the bed') unless the context makes it clear which type of bed is being referred to or the sentence itself dictates the article (i.e. 'She lay down in bed').
