SleepDog mattresses are constructed with memory foam, which is a material known to be hypoallergenic. Thanks to the density of memory foam, there is little room for bacterial growth or dust mites to burrow in your truck mattress. To add an extra layer of protection, our Sleep Tite Pr1me Terry Protector is also hypoallergenic, liquid-proof, and creates a barrier between your mattress and allergens or dust mites.
