Product Description: Bassett Furniture 2852-K3-25 Z4 Track Arm King Sleeper Sofa - At first glance, the Z4 Track Arm King Sleeper Sofa invites the eye with its clean lines and modern style. But there’s more to this amply-sized, 3/3 cushion sofa than meets the eye. The sofa bed opens to reveal a plush King size mattress. Back cushions are loose so you can rotate them or remove them when in sleep sofa mode, and you have the option to select your preferred Bassett comfort seat cushion. Our Z4 Sleepers are engineered around a European-style mechanism that is much lighter and incredibly easy to operate. Your track arm sofa style can be tailored to reflect your style with your choice of designer fabric, with more choices of fabric and leather upholstery available in store.
