Which is better for a large living room?

The Costway. It is 101.5 inches wide, U-shaped, and seats six. The Rhylin is 82.7 inches wide and built for compact spaces.

Which is better for a small apartment?

The Mercer41 Rhylin. Its 82.7-inch width and reversible chaise let it fit tighter rooms and switch sides.

Is the Rhylin worth $26 more?

If you want chenille, coil-and-foam cushions, a 900 lb capacity and a reversible chaise, yes. If you need six seats, the Costway is the better buy.

The Rhylin is the safer bet. It has coil and foam cushion fill and a 900 lb capacity. The Costway uses sponge fill and carries only a 90-day parts warranty.

Do either need assembly?

The Costway states assembly is required. The Rhylin ships as one piece, though the chaise is reversible.

Which has a better return window or warranty?

The Costway lists a 90-day parts warranty. The Rhylin lists no warranty, so check the store's return policy before buying.
