The iCool® gel memory foam mattress comes in a range of special RV sizes and offers a comfortable night’s sleep. Gel foam lowers body temperature by about 2 degrees on average. Traditional memory foam tends to trap body heat, making you sleep hot, especially during summer months. iCool® mattresses are engineered to offer cooling comfort all night, regulating body temperature during any camping season. The iCool® mattress offers excellent support and features a residential-style circular knit cover.
