The Mattress that comes with a Kenworth

Professional drivers often choose Kenworth trucks because of their quality, safety and overall comfort. However, the quality of the factory mattress most Kenworth trucks come equipped with doesn’t generally live up to the same standard. Although these stock mattresses work well for quick naps or occasional use, many long-haul truckers find them lacking in essential comfort features. Typical complaints of factory installed mattresses include: inadequate support and lack of durability motion isolation. Due to these issues, many Kenworth drivers opt for high-quality aftermarket mattresses, like SleepDog®, to ensure they get the rest they need.
