The foundation of the trucking industry in America is the Freightliner truck. Professional drivers rely on these heavy-duty vehicles because of their dependability and cutting-edge technology. Freightliners are built to last, whether you're transporting cargo across the nation or making local deliveries. However, the quality of sleep truckers get while making long hauls in a Freightliner is often an afterthought. The factory-installed mattress is primarily intended to satisfy basic sleep needs at the lowest possible cost, which might make a truck mattress upgrade necessary sooner rather than later.
SleepDog® mattresses are designed to offer the same degree of support and comfort that you expect from a premium mattress at home, while on the road, and in a selection of sizes that are compatible with most Freightliner sleeper cab configurations.
In order to accommodate different Freightliner configurations and personal sleeping preferences, SleepDog® mattresses are available in a variety of styles and sizes. Most Freightliner sleeper truck models can be upgraded with a SleepDog® truck mattress.
