Assembly is impossible. They forgot to drill 2 holes which we can do ourselves, but they also didn't drill the hole properly in the metal rod on one end of the back of the bench, so we need a die cast set to redo that. The 2 arms didn't come assembled completely at the factory which there are no parts for and no instruct for. Lastly, of course customer service is experiencing a high volume of calls and we can't be helped at this time. Don't buy this traditional polywood glider. The workmanship is terrible.
