Love this chair!  I bought this for my tween son's desk/crafting table instead of an office chair or gaming chair.  It has the mid-century mod look we were searching for and it swivels:)  

Made of very sturdy materials (very thick non-flexible plastic seat, metal base, and soft but dense cushion with fabric cover.)  Assembly was just stuffing the cushion into the fabric cover and attaching the seat to the base (small tools were included along the bolts).   

Worth every penny!
