Sectional Sofa Buying Guide – How to Choose the Perfect Corner Sofa Set
A sectional sofa is the centrepiece of any living room — it sets the tone for the entire space and needs to work hard both aesthetically and practically. With so many configurations, fabrics, and sizes available, this guide will help you navigate every decision with confidence.
1. Understanding Sectional Configurations
- L-Shape (Corner Sofa) — The most popular configuration. One long section and one shorter section meet at a 90° angle. Ideal for corner placement and open-plan living rooms.
- U-Shape — Three sections forming a U. Maximum seating capacity. Best for large rooms and families.
- Chaise Sectional — A sofa with an extended chaise longue on one end. More compact than a full L-shape but still offers a lounging option.
- Modular Sectional — Individual pieces that can be rearranged. The most flexible option for changing layouts or moving home.
2. Measuring Your Space
Before falling in love with a sofa, measure carefully:
- Measure the room and mark out the sofa footprint with tape on the floor before ordering.
- Allow at least 90cm of walkway around the sofa for comfortable circulation.
- Check doorway, hallway, and staircase widths — sectionals are delivered in sections but individual pieces can still be large.
- Consider ceiling height — high-back sofas can feel oppressive in rooms with low ceilings.
3. Choosing the Right Fabric
- Velvet — Luxurious, rich, and tactile. Adds instant glamour. Best in low-traffic rooms or homes without pets.
- Bouclé — Textured, warm, and on-trend. Suits contemporary and Scandi interiors.
- Linen / Cotton blend — Breathable, natural, and relaxed. Great for casual living rooms.
- Leather — Durable, easy to clean, and timeless. Improves with age. Ideal for high-traffic homes.
- Performance fabric — Stain-resistant and easy to clean. The practical choice for families with children or pets.

4. Style & Aesthetic
- Contemporary / Minimalist — Clean lines, low profiles, neutral tones. Legs in metal or tapered wood.
- Luxury / Hollywood Regency — Velvet upholstery, button tufting, gold or brass legs.
- Scandi / Organic — Natural fabrics, wooden legs, muted palette.
- Modular / Architectural — Geometric forms, bold colours, statement presence.

5. Comfort Considerations
- Seat depth — Standard is 55–60cm. Deeper seats (65cm+) are more lounging-friendly but can be harder to sit upright in.
- Seat height — Standard is 42–45cm. Lower seats feel more relaxed; higher seats are easier to get in and out of.
- Back height — High backs offer more support; low backs create a more open, contemporary look.
- Cushion fill — Feather and down is the most luxurious but requires regular plumping. Foam is firmer and more low-maintenance.
6. Practical Features to Look For
- Removable, washable covers
- Built-in storage (ottoman sections)
- Sofa bed functionality for guest rooms
- USB charging ports in armrests
- Recliner sections for ultimate comfort

Frequently Asked Questions
What size sectional sofa do I need?
For a standard living room (4m x 5m), an L-shape sectional of approximately 270cm x 200cm is ideal. Always mark out the footprint with tape before ordering.
Which is better — left-hand or right-hand facing?
Stand at the sofa facing it — if the chaise is on your left, it’s left-hand facing (LHF). Choose based on your room layout and which side you want the chaise to face.
How long should a sectional sofa last?
A quality sectional sofa should last 10–15 years with proper care. Hardwood frames, high-density foam, and durable upholstery are the key indicators of longevity.
Can I add extra sections to a modular sofa later?
Yes — modular sofas are designed to be expanded. Check with the manufacturer that additional sections are available in the same fabric and finish before purchasing.
