Seat heights vary by model but typically range from about 15.8" to 30". Seat depths commonly fall between roughly 22.5" and 38".
Most 80" sofas are listed as seating 2–3 people. Many listings state “Seats up to: 3,” while a smaller number list “Seats up to: 2.”
Delivery and setup vary by model. Some 80" sofas arrive vacuum-packed with no assembly and require about 24–48 hours to fully expand. Others ship with assembly tools and can be put together in under 20 minutes.
Care guidance varies by model. Common recommendations include spot cleaning or wiping and light vacuuming. Some fabrics require dry cleaning only, and a few listings do not provide care instructions.
Common upholstery materials include chenille, polyester, cotton, velvet, and suede.
Convertible mattresses are listed at about 80" L × 76" W × 7.9" H. They ship vacuum-compressed and typically need about 24–48 hours for the mattress and cushions to fully expand.
Weight capacities vary: some listings give total capacities up to about 750 lbs, while others provide per-seat ratings such as 300 lbs or 250 lbs per seat. Construction notes often mention metal frames, solid wood or plywood frames, reinforced legs, and similar reinforcement details.
