The idea of ​​a bucket seat partially implemented well.

It is in this chair at an excellent bucket seat, a very stable construction. The backrest is exemplary high, so that the head is involved. You can also adjust to any desired position by operation of a lever, so you can sometimes sit back and relax. The armrests can also be adjusted to desired positions. Of the two ingredients, I mean the head support cushion and the lumbar support, the head support cushion is most useful. For the lumbar support to the seat depth is not sufficient.
What prompted me to return the chair again, on the one hand the seat depth that is specified in the product description with 52 cm. In fact, it is only 44 cm, so much too small. For comparison, the seat depth is in my car (a sports coupe) 50-51 cm.
Secondly, the seat height is specified in this chair in the range 41-51 cm. In fact, it is 49 cm to 59 cm, so much too high for smaller people. I am 176 cm tall. The tilt function I could in the lowest position almost not use without a footstool. And higher seating positions did not come for me anyway in question, because then my feet barely touched the ground, ledigtlich tiptoe.
Amazon has since taken over incorrect data.
