The ultimate in stylish and functional comfort, the Dunlopillo adjustable electric base is a fluid harmony of practicality, innovation and design. The sprung birch wood slats individually flex to your body shape, weight and movement providing a firm yet supportive foundation to your Dunlopillo mattress. As with the slatted base the firmness of the system can also be controlled through the use of cleverly designed comfort adjusters positioned in the lumbar region of the system. Moving the adjusters to the outside edge of the system will create a firmer feel, whilst positioning them centrally will create a softer feel. Individual remote controls allow you and your partner to adjust the back and leg areas to find your perfect comfort position. The wireless remote control even functions as a torch so you do not have to disturb your partner and can be easily stored away when not in use.
