    TERRIBLE product.

    I put the chair together the exact way it said in the manual and then the stick to recline it completely jammed and made the whole chair break. This chair is the worst chair i have ever sat in and this whole thing ruined my day. 100% would never recommend this to ANYBODY at ALL.

    Decent for the sale price of 155$

    Chair is decently comfortable however the limited 2 settings of tilt is a bit of an annoyance. I definitely would not buy this at full price.

    Wife’s chair

    I purchased the chair for my wife to use when she does her sewing. I assembled it without the arms so they don’t interfere with her arms. She is very comfortable in the chair and extremely happy with it overall.
