Check the exact outside width, including arms. A 79-inch sofa with thick arms can offer less seat room than a narrower sofa with slim arms. Compare seat width and number of usable seats.
Compare depth and comfort
Look at overall depth, seat depth, seat height, and back height. A shallow sofa preserves floor space, but sit in a comparable model if possible. Check if the back and cushions suit how you actually sit.
Check materials and upkeep
Read the maker’s fabric care directions, frame and suspension details, cushion construction, warranty, and return terms. Performance claims vary by material and testing method. Order a swatch when color or texture matters.
Check delivery dimensions
Measure the whole route and ask for boxed and unboxed size. Removable legs or a boxed modular design can help in a walk-up, provided the maker permits assembly in the room.
Make a three-model comparison
For each model, record outside width × depth × height, seat dimensions, largest delivery piece, price including delivery, return charges, and warranty. Reject any model with an unresolved access point before comparing style.
