Upgrade your sleep setup with our collection of self inflating mattresses (SIMs), specifically shaped for campervan beds. Unlike standard camping mats, these are designed to fit the specific dimensions of your van’s interior, providing genuine support and thermal insulation that turns a bench seat into a luxury bed. For the gold standard in van comfort, the Outwell Dreamboat Campervan is a top-tier choice; it features a tapered shape designed to fit perfectly between the wheel arches of most mid-sized vans, along with heat-regulating foam that keeps you cool in summer and warm in winter. If you have a rear-folding seat system, the Outdoor Revolution Rock n Roll and Vango Rock and Roll mattresses are essential kit. These mats feature a ‘notched’ design or specific dimensions that sit flush against your van’s cabinetry, smoothing out the lumps and bumps of your seat cushions for a seamless sleeping surface. We provide the high-performance campervan SIMs you need to ensure you wake up refreshed and ready for the next leg of your journey.
