That's tremendous value and it will be miles better than any new £100 office chair on the market. I bought a Steelcase Leap v1 for £80 back in 2008, and since then only look for bargain refurb/used chairs from reputable manufacturers. I'm thinking of going Herman Miller Aeron in the future...I picked up a Herman Miller Mirra for £100 recently. Bargains are out there!
