The chair is high quality you may need an extra hand to hold while screwing all tools are included. Knowing front and back may be an issue however it is only four screws and easily fixed.
They had this chair in red in the store sat in it and it was great. I got the same exact chair only in grey and its incredibly uncomfortable. The arms are way wider [ we measured and its 2" wider box says same dimensions] so I can't rest my arms on the armrest. Suggest you try the grey one before you buy.
