The Haley 110 uses all high performance foam with no cotton, but rather a poly-dacron blend, making the mattress much lighter. This futon is great to use on futon frames as a primary sofa or bed. For a premium high performance foam futon mattress, this is a great choice for daily sitting or sleeping, opening and closing your frame daily. This mattress simply will not bottom out and will retain it's density for at least 10 years. It's extremely comfortable and is considered a medium firm futon. It will simulate a sofa cushion feel unlike the cotton futons which tend to get harder over time. If you are using this mattress on a futon frame, it is highly recommended that the frame be of quality wood with thicker arms. The arms weight down the body of the frame facilitating the conversion from bed to sofa. If you plan on putting this on a futon frame that does not have arm rests, it will be better to get the Stratsophere 6" mattress by Otis instead.
