The Standard Mattress is a series of comfortable and durable polyurethane foam mattresses designed for use with HAY's Tamoto Bed and Connect Bed. Depending on the user's preference for a firm or soft mattress, the core is either made with strong support foam or soft support foam, with both variants featuring a layer of memory foam quilting on the top and bottom. All the mattresses are OEKO-TEX® certified and are available in different sizes to fit the various bed models.
