Yes, it is correct to say "pieces of furniture." The phrase is commonly used to refer to individual items within the broader category of furniture. For example, a chair, a table, or a sofa can each be described as a "piece of furniture." The term is particularly useful when you want to specify or count individual items rather than referring to furniture as a whole.

For instance:

• "We bought several pieces of furniture for the new apartment."
• "The living room is furnished with a few key pieces of furniture."

In these examples, "pieces of furniture" helps to emphasize the individual components that make up the collection of furniture in a space. It’s a versatile and widely accepted phrase in English.
