My chair is from OfficeMax, chair from Staples.

All my stuff back in England came from Ikea in Lakeside, so just up the road from you... But if I was buying in that area again I'd go here: http://www.green-work.co.uk/silvertown.htm - great bargains including some nice L shaped desks that will fit nicely in the corner of any room and house two monitors with ease - and less than an hours drive from you.
