I have now for a week this Playseat Challenge in my home. I am amazed at how high this was produced. At first, I thought at first, that is probably a loose game, how stable this can already be folding chair. After a very short Aufbaufase I could convince myself of the functionality and stability of this Playseats. The enclosed assembly instructions I have not needed because the structure is self-explanatory in itself. You can adapt this Playseat convenient Velcro system to its body size. Does that mean that you can adjust looser or tighter the seat and the backrest. You could also the armrests, which are also made of Velcro so set that one is more or has an upright sitting position. The pedals can also be easily attached to the designated device of the Playseats with Velcro that holds bombproof. No more slipping of the pedals! I find also good that the manufacturer nor several Velcro packed to to ensure a reasonable attach the cable. To attach any cables in the way, or between the feet. Accessories include also various Allen screws and Allen wrench to attach a wide variety of steering wheels. I've even bought a seat on this Thrustmaster TM300RS, the holes in the seat fit perfectly with the steering wheel, so I could attach directly to the chair of this with the enclosed screws. The steering wheel itself is mounted on a fold-out stand on the seat. One has then the chair down a small pen which you can pull out so that the flaps to the side of the steering wheel the chair from tipping over. Genial! So you can enter from and very easy It is very convenient while driving, driving even after prolonged, I have no back pain. All in all I can to anyone who wants know about this a Racing Seat. He is to save space, you can easily put away him in the folded state and the steering wheel is also the same as tidy as it is firmly attached to the chair. Strong buy recommendation.
