Impressive Chair for the price!
Color: Black
Purchased for my mother, she absolutely loves it. She used a secretary style chair forever and said she didn't want a big bulky chair like the executive type until she saw this one. It's comfortable like an executive chair but not quite a big or cumbersome as the executive can be. It took a hot minute to put together but well worth it. Instructions were very clear and easy, I'm in my 60's, if I can put it together anybody can! Chair is well made, solid!
