Zaisu (floor chair) - Nursing care supplies - Chair for nursing care

I believe it is in relatively good condition.
I purchased it new about 2 years ago, but after sitting on it once, I placed it in another room intending to use it later. Time passed, and now I am listing it.

I could not find any size specifications, so please refer to the amateur measurements below.

Amateur Measurements:
Width: 52cm
Depth: 45.5cm
Height to seat: 33cm
Overall height: 59cm

Material:
I am unable to determine the material.
