When did they (regular people, rich people, etc.) start using stools and benches in the British Isles? My question is about daily life, not just the earliest archaeological finds. Specifically, I'm wondering when constructed furniture (as opposed to logs, rugs, just sitting on the ground) became typical in an ordinary person's home (hut, roundhouse, etc.). 

This article on the [history of furniture](https://www.sofasandsectionals.com/the-history-of-furniture) gives some details:

> 
> Furniture from 500-1500 A.D. (Or ‘Medieval furniture‘), was designed
>  in European *[sic]*. Chairs were popular for seating and were often made of
>  heavy oak with exquisite artistic designs.

Is it possible to narrow down this 1,000 year time span to something more specific in relation to the British Isles?

Wikipedia isn't much more helpful on this but would seem to indicate no earlier than the late medieval period.

Can anyone provide any more details the use of furniture in the medieval (or perhaps early modern) homes of ordinary people?
