The staff at Atlantis have been prompt, helpful and delightful. The product was received timely and well packaged, the chair is of very sturdy construction, albeit one of the bolts does not fully thread into one of the holes that attach the back of the seat to the base, I haven't felt any lean or wobble in the slightest, a telltale sign of a poor choice of materials and design. I have recommended my friends the company as most of us are tall and stocky build, or, have all become sick of £150-£200 plastic office chairs or metal office chairs that aren't built up to standard for the non-petit operator, and don't stand up to use or time. I am becoming more certain that the next office chair purchase, should there need to be one, will be from Atlantis, and that it won't be for quite some several years, whereas it was barely 10 months with other 'standard' office chairs before. 10/10 from me, so rated 5/5 stars as that is the maximum on the survey, A big thank you to Atlantis Office and their team.
