community mattress. but dont be fooled by the weird name, its a custom manufacturer that specializes in boat mattresses, and weird shapes and sizes. they can even make mattresses for dogs... :D which is why i mention it, besides the joke about the name being strange.

in business since 1960. best dang mattress i ever had.

now i have a simmons beauty rest and its aight but i liked the other one a lot more
