I am an heavy weight, and it i snot easy for me to find a chair comfortable.
I have open the box, instructions are not detailed like Ikea, but in the end they are quite clear.
Base-wheels-upeer with lower part of the chair-lateral protection-piston-support under the chair
Assembling top on the base in a click, took me around 10 minutes.
Considering the price, i was very surprised about the level of details: the fabric is like "alcantara" effect, so it is lovely at touch and looks like a good quality and durable textile, no defect, each details is very well done, then 2 plastic coverage x side to made the chair looking better, some extra nuts in case you got problem, details that are not usual part of a cheap chair.
Seating is firm, so for people that prefer to sit on a soft place should look somewhere else,
But after few hours, the seating i so comfortable, also for big bumper like mine.
CONCLUSION:
So I have to say that I was surprised about overall quality and the comfort of the seat.
Perfect fit for heavy weight
