Whether providing a seat or an overnight stay, our Sombra is a supercomfortable, design-conscious sleeper sofa with lots of extras. Clean lines, buttonless tufting and convex-contoured track arms capture the eye, while seat and back cushions offer soft-yet-supportive comfort. When it's time to retire, the sofa unfolds a plush, high-density mattress that's eight inches longer than traditional sleeper mattresses. Your overnight guests will thank you for the sleep-inducing comfort provided by the high-density mattress. The sleeper requires zero wall clearance so feel free to position the sofa right up against the wall—a great option for small spaces.
