My husband has just put these up today. He did it really quickly and said there were no problems. They look so sleek and modern and fit our space perfectly. Love the dark grey and wooden back. They don't look cheap at all. One thing they are very light and the base is plastic but it doesn't look bad. My husband weighs over 200lbs and they can take his weight and he can adjust while sitting on them with no issue. Great buy, really pleased with them.
