We just ordered another BOSS seat today. Boy, the cost's sure have went up. With shipping $573.40, WOW! I would have to say though, BOSS is a great company to work with. I had a problem with two seats which had broken Zippers. 3 years old. BOSS replace all the zippers on both seats at no charge. I just had to pay the shipping. The both look brand new now. I am very happy with the customer service and will further along business. I just wish other companies would be as accomadating. That is why I place an order for another. Now even the Guest sleds are riding with BOSS. Thanks Al
