Practical furniture advice from OROA, helping you make thoughtful decisions for a home that works as beautifully as it looks.

What to know before you buy

Understand the difference between overall sofa depth and seat depth. Many standard sofas measure roughly 34–40 inches overall, while deeper lounge styles can reach 40–45 inches or more. Compare usable seat depth, cushion firmness, seat height and back support rather than choosing by appearance alone.

Measurements, materials and layout

For a comfortable layout, allow approximately 14–18 inches between sofa and coffee table, and where possible 30–36 inches for a primary walkway. Tape out the sofa footprint and measure delivery access including doorways, elevators and hallway turns. A sofa for relaxed movie nights may need a different profile than one designed for conversation.
