First time buyer on Wayfair. Was skeptical of quality based on other reviews. But was pleasantly surprised at the high quality of product, including fit and finish. Very simple to assemble - less than 10 minutes from unpacking to usability. Included instructions were clear and no parts were missing. Don't need instruction if you have assembled similar chairs before. There are four parts to assemble - the base, the main adjustable 'spring', the footrest, and the seat. All fit in nice and easy. Holding off on 5 stars since I don't know how durable this will be. For the price of about $80 per chair, I am good if it lasts at least two years. Would recommend to anyone looking for a decent bar addition at reasonable price.
