They are actually both the same mattress! We just market them both differently since we found that most shoppers looking for mattresses for their kids loved it, but its also popular with folks looking for RV beds, bunk beds or other applications where space is a premium and the low-profile 6" height is a big plus.
The HIBER6 and HIBERNate can both work well for children and adults depending on their weight and sleep preferences. We have created name HIBERNate Kids Mattress to help parents, family and friends find a safe, healthy and comfortable mattress for their little ones easily.
