After extensive research I settled on the Atom GT Black Edition. There are a lot of chairs out there. Working in IT I have tried many. The Atom arrived very well packaged with everything in perfect condition. The chair went together in about 20 minutes. It was easy and the simple instructions perfect. I am extremely pleased with the quality of this chair, the level of comfort and it’s adjustability. The arm rests are particularly good, but for the price the whole chair is magnificent. I would also like to add that abroco communicated faultlessly and my chair was delivered very quickly. Thanks guys. Awesome product.
