Durability and stability: A well-made standing desk should be durable and is expected to last several years, but it's always wise to check the manufacturer's warranty. Your desk should also be stable, meaning that it doesn't sway if you lean your elbows against it and there's not much shaking or moving when the height is adjusted.
