Serenity Series Koala Mattress

Selling like new Serenity Series Koala twin mattress still in its original packaging! The dimensions are 6 x 39 x 74. It features a core made of polyurethane foam and a cover made of a cotton polyester blend. The mattress is firm. Good for people who suffer from back pain. Got as a set with the bed frame but need to change the mattress for a softer one.
