Slats are the most common type of mattress support system used on bedsteads. A base with sprung slats features curved wooden slats, usually made of beech, which sit within the frame. The natural bounce in the slats means that they will adjust to your profile where you exert the most pressure. This sprung slatted base has 18 slats each 53 mm. The total hight of the sprung slatted base is 5 cm. This version has a movable head and foot part.
