Review: Sehr guter Stuhl für den Heimgebrauch - Nachdem preiswerte Stühle aus dem Möbelhaus zu schnell kaputt gegangen sind musste ein ordentlicher Stuhl für zu Hause her. Ein professioneller Bürostuhl ist es zwar nicht, das ist bei dem Preis auch gar nicht möglich. Für täglich ein paar Stunden am PC ist dieser Stuhl aber sehr gut und ich würde ihn sofort wieder kaufen. Sein Geld ist er allemal wert. Man sitzt bequem und er hat reichlich Einstellmöglichkeiten. Der Stoff macht einen strapazierfähigen Eindruck. Insgesamt wackelt und quietscht nichts an dem Stuhl (nach 2 Monaten in Gebrauch). Die Aufbauanleitung ist dürftig. Zum Glück ist der Aufbau im weitgehend selbsterklärend. Ein Schraube blieb übrig, ich nehme an, die war als Reserve zusätzlich im Beutel??? Ein wirklicher Schwachpunkt ist die Verpackung. Die Einzelteile sind untereinander nicht ausreichend geschützt. Da kann es schnell zu einem Transportschaden kommen, wenn der Paketdienst mal wieder etwas ruppiger zur Sache geht.
