We bought two and assembled them ourselves. We found we needed two people at the end to balance the unwieldy parts but as two older women it was relatively easy. They provide the allen wrench the only tool you need. We bought extra lumbar pillows to balance out the fit for ourselves. We got the chairs on sale from the website and are happy with them.
Got for my son since he is working from desk in his room virtually and his old chair was killing his back. Great quality for price!! Looks modern and nice. He put together himself with no issues. He is 6'4" and fits in it nicely and really likes it.
I purchased this chair for my grandkids but as soon as I got it put together they’re mom (my daughter) was the first one to sit and spin. They love the chair so much my granddaughter spends hours in it practicing her math skills.
