Education Budget (<£200) desk chair recommendations

I managed to get a decent Senator chair from Facebook marketplace, delivered for £50.

 

Ended up finding one locally for a great price and just needs a bit of TLC on some of the plastics etc

 

I was also similarly looking for a budget and comfortable chair and then I found my chair of choice here. It's Hbada ergonomic chair and it's quite comfortable and supportive for me.
