The Comfort Sleeper is unlike any sofa bed you've ever experienced. There are no bars across your back, no noisy compressed springs in the mattress, just pure comfort—that's why American Leather calls it the only sleeper sofa you can sleep on. Experience ultimate comfort on either the 5" plush, high-density Premier foam mattress or either of the optional upgrades of Gel or Tempur-Pedic®, extending out 80 inches on all mattress sizes from cot to king. Your guests will rest easy, as will you with the Comfort Sleeper's 10-year warranty on the mechanism and lifetime warranty on the frame.
