Purchased the EXTRA LARGE Couch Bed for when my daughter brings her big boy in for the weekends; well, he just settled in this oval and enjoyed the comfort as he was "lights out" in no time; also noticed he liked having his head comfortably perched on the blue ring circumference; VERY PLEASED with this purchase.. then I saw the "SERTA" BRAND name on the tag, and then remembered thier mantra...."Serta PERFECT sleeper"... absolutely right!!
