I have had a Seville Airlift for some years and always wanted another one at a price that I can afford.
All a sudden I saw this Yulukia and thought I could give it a go. The first desk was perfect. It was easy to assembly by one person and everything works really well.
Planning to have a desk like this in every room, just in two days I have bought another one. It is nearly as good as the first one but it took longer time as I had to find a pair of pliers to force one of the screws in. The Gas Spring System is not smooth and there is some kind of rubbing sound when the desk is been adjusted.
Just submit a question asking whether I can do something about it. Hopefully I will get an answer soon. I don't like to return things if I can help.
