Thank you, CalifJim. Would you mind telling me if the following, which eem to be examples given by Aperisic, is hovering in the theoretical realm and not touching the reality of things?
I have furnitures in my house such as Louis XV, Louis XVI and Louis XVII furniture.
Personally, I would rewrite to insert the phrase 'many different types of ' like this:
I have many different types of furniture in my house such as Louis XV, Louis XVI and Louis XVII furniture.
How about this example given by Aperisic? Is this realistic or the most theoretical in nature to you?
The furnitures we have are: commericial use furnture, counter system furniture, job station furniture, retail counter furniture.
Sorry to make you delve into a not-too-pleasant area of English learning.
