I purchased a HAG office chair (HAG HO5) when I set up my first home office in Germany in 2005. Now, 15 years on, and after my move back to Nova Scotia, Canada, the chair is still fully functional, despite having sustained my - on average - 10-hour working day, 6 days a week during all that time, and without requiring any maintenance. These chairs really have your back - in terms of comfort they are second to none. When, recently, I needed to purchase more of these top-quality chairs for my company in Nova Scotia, I was extremely pleased with the customer service provided by the people at Ugoburo, who went above and beyond my expectations to meet all my needs, including a special order.
