The head rest is extendable.
I avoided the DXracer tbh. I find bucket seats very constrictive, especially after doing a 20 hour drive in one lol.
I did think about getting a very high end Sparco with massive bottom padding but it would have worked out to about £450 or more.
The chair I got retails for around £570 for the base model. Time you add in armrests and fabric on the arm rests instead of plastic it comes out to about £700. I managed to find an upholsterer that buys in damaged chairs (rips and so on) and then refurbishes them completely. The base is repainted and the fabric all completely replaced. You even get a choice of colour too and the guy has a good reputation
The rest of the chair (body and so on) are all carbon. Not Carbon fibre, more like graphite.
The best bit? he charges £200 collected or £250* delivered (I agreed to pay a £15 surcharge via PPG to cover his Paypal fees).
That's one hell of a lot of chair for £250. Especially when you consider it's been completely reupholstered and therefore pretty much new.
Plus my living room is all 1920s and Art Deco. I'm sure my wife would have had my balls if I stuck a bucket seat in there lol. That's why I chose the colour I did because it's close to the duck egg accents in the sofa we have.
