Not so Good quality plastic

I am disappointed because I did not really have to try it ... I ride a half-and I fall on a defective part, the adjustment wheel of the seat under the seat was broken and falling by cotta outgoing, but I think it's made in the arrangement of parts in the package that makes it broke during transportation ... shame !! (Hoping that it could help the manufacturer)
Given the quality of the plastic, I do not know if the armrests and base with wheels will therefore resist I hesitate to recommend I saw the price.
On the upside because there are:
- The speed of amazon: arrived a day before the scheduled time
a switch to negative (- the seat and back look pretty good: good leatherette padding so dense and firm, not limp (it's to do with time).)
- The armrests can stand parallel to the file which is handy if you do not need
- Different adjustable seat: tilt stopping (+ setting according to the weight per wheel) and seat height
For negative points:
- Design / quality of some plastic part not very solid.
- Lost 2 evening for the assembly / disassembly and removal (I do not know if you can count it ^ _ ^).
- Considering the price compared to the quality of the plastic take much less if it's not hard to make it a few years
- Assembly between the backrest and seat are made by brackets that are associated with armrests: I do not know if the 4 screws on each side are seen or solid they are placed but it is just my opinion

Overall this is a good seat except the default one piece I'll probably be 4 or 5 stars, so I put 3 stars

Edit of 11/12/13:

I have recommended and I am only more overwhelmed by the poor quality of this seat ... I even think I'll return the saw:

- The seat cushion should be of greater density than the record !!! if you want your behind any dish that's part: D (that is flat and not the shape of your back) after 2 weeks we buttocks that are on the board under the padding !! and not even talking to one armrest, there is the trace of the screw on the imitation leather ... (I'm not even yet 80kg)
- Clearance between the seat and the pneumatic column (under the seat in such a short time ...)
- The wheels braking ok !! but it's better if it could ride ... they are not anti-slip so it rubs on the ground (if sliding) instead of rolling and rolling it to be sitting on a non-slippery floor, but has a little trouble anyway.
- Adjusting levers of the height and inclination misplaced !!! situated not far from the record of each side, backwards so (less annoying without armrests)
- The backrest is a block since it is fixed to the seat (it was more the foot down) and it's embarrassing for me if I want to get up without changing the inclination towards back (which is maxinum)
- No head support if you are too big (no more than 1.6m)
- The only solid metal pieces (the rest is almost all plastic): the base under the seat pneumatic cylinder (oufff and screws)

In short I have a pain in buttocks, back and even ensconced in the seat I'm less comfortable than in my old seat with a comfortable seat (well padded that marries well the forms) and just a manual recliners without armrest and rolling. it was a second-hand seat recovered so voila ... I put zero stars for the one
