Inspired by mid-century modern looks, the four panel back cushions and sides of this sofa bed are accented with a button that boasts a finely tailored look. Tufted in High Density Polyurethane Foam, it provides support and comfort for extended periods of sitting. Converting the sofa is easy – just pull the strap from behind the back cushion and the bed tumbles out without much effort. Converting from a bed to a sofa is just as easy by lifting the foot of the bed and push it forward. The mechanism is designed keeping in mind that only minimal effort is required. The sofa bed base is made with solid steel tubes to hold up an independent left and right side birch slat mattress base to provide the best in comfort and support. No springs, no saggy feeling, no lumps and no squeaks. True US Queen Size mattress ( 60” x 78” ) takes standard US Queen Size Sheets. Mattress cover is removable and washable for the ultimate in hygiene. Made in Italy with Quality Components by artisans who have been practicing their craft for multiple generations. This sofa bed is covered in 100% Genuine Top Grain Leather throughout. Unlike other cheaper models, the same leather on the seating surface is used on the sides and back even when it does not come in contact with the user. Using the same material eliminates wrinkles and stretches as the seasons change and eliminates that different feeling due to fewer quality materials like split hides or synthetic materials.
