Need a new chair

[Morti]

So my old chair finially broke, never liked it much but it was well built, withstood my fat-ass for longer than I expected.

Now, I need a new one, but I could really do with some recomendations. My conditions:

0) I'm in the UK.

1) I'm after quality, something that is super comfortable for long sessions and will last a long time.
2) My aforementioned fat-ass. I'm about 130kg so a flimsy thing isn't going to cut.
3) I use both my PS3 and PC from the same desk/chair, so it does need to be an office style chair and not a lounge chair.
4) I do like to recline, headrest would be nice.

Budget: My father has agreed to go halves for my birthday, so I can push well into tripple digits. Say about £200 as a soft cap, £300 hard cap if Thor himself recomends it.

Any advice anyone can provide would be much appreciated.

I can't make any specific recommendations since I'm a cheap ass and am currently sitting in this [http://www.officeworks.com.au/retail/products/Furniture/Chairs/Leather-and-Plush-Chairs/OWSCOPEBK] because, despite becoming uncomfortable when I occasionally end up spending an entire day in it, it's got a solid metal frame and is likely to serve me for longer than most cheap comfortable chairs. That being said, this is probably the sort of frame you should be looking for since the plastic ones tend not to last. Definitely also take time to inspect the covering material when making a choice since, at least in my experience, even the expensive ones tend to be made of total garbage.

With that budget you can get a decent "executive" office chair.
-Avoid leather ones if possible as they begin to tear apart after a couple of years and they look gross.
-Prefer the ones with a metal base.
-Most websites provide a weight limit for their office chairs so take a look at that before purchasing.
