I went to Morrisons yesterday and saw these chairs with a big sign saying 'Special Purchase £25'. I was quite pleased as I had just been to PC world looking for a similar chair and their cheapest ones started £50 (except those tiny ones).
The picture isnt the exact picture of this chair but its the most similar I could find, it is a leather style - obviously not real leather.
It is quite a large box and weighs 11kg, but saying this I still managed to get it home on the bus :) It was very simple to put together - it was all allen key screws so didnt even need to get the tool bag out and even better didnt need to bother my OH.
Hope this helps someone :D
