What our customers say
"Today Kevin visited me in Eastbourne, to set up a height adjusting desk, footstall, keyboard stand, mouse and chair. I just wanted to say how patient, and caring he was. He really helped me and I think he should be commended on how friendly, polite, informative and down to earth he was. Thank you Kevin and Ergonomics."
