Disadvantages of butterfly chair: the lifting armrest is too high (even if minimized), and the adjustable range of lumbar support is too small. When the back is minimized, the position of the lumbar support is awkward. (The lumbar support should be linked with the reclining design) The mesh of the cushion is not tight enough, and it obviously collapses after sitting for a long time (I don't know if it is a production problem). This is a product that conforms to European and American body shapes. It is not suitable for Asians to use it for almost a month. At the same time, they bought another similar brand, which was a little cheaper, but it was really incomparable. Ergoup supports the waist very well, the lying angle is also large, and the seat has high elastic comfort.

Insufficient horn chair: there is no armrest, which brings inconvenience to the elderly. A fatter person may get stuck and can only use it by one person. The smooth surface is convenient for people to slide the horn chair during the operation. The disadvantage of wood is that it is afraid of crying, takes up a lot of space, sits for a long time, and needs a pad, otherwise the ass is uncomfortable.
