Despite warnings of my mum that Argos only sell cheap rubbish and I should avoid them I bought a new swivel chair for them costing me £45. I have used it for two hours and the its now warn down so badly that I feel a sharp object when I sit on it, its the base screws, this should only happen after 12 months or so. Also it dosn't have any of the 1988 safety stickers on which i thought all foamed furniture in the UK had to have since the 1979 Manchester woolworths fire. Am I in my rights to take it back even though its been used? I am not sure if you can dismantle the gas lift once its been assembled.
