Black Friday Sofa Size Guide (UK): Corner vs 3-Seater + Free Delivery & Assembly

Shopping a sofa on Black Friday is exciting — but nothing kills the mood like discovering it won’t fit through the door. Use this quick guide to pick the right corner or 3-seater for your space, and lock in our Black Friday savings with free UK-wide delivery & assembly. 

60-Second Measuring Checklist (do this before you fall in love)

• Measure the room: width × depth × height. Note the usable footprint after rugs, radiators, doors, and walkways.

• Map the route: building entrance → corridors → stairs/lift → room door. Measure widths, heights, tight turns, and ceiling drops.

• Door math: doorway width should exceed the shortest packaged side; diagonal clearance matters at tight angles.

• Leave breathing space: ideally 60–90 cm of walkway in front; 10–15 cm from walls for radiators/skirtings.

• Delivery prep: clear pathways, secure pets, protect door frames on narrow turns. (See our Delivery Prep & Checklist.)

Corner vs 3-Seater: a quick decision tree

• Is your room wider than 280 cm and open-plan?
  → Go corner to define zones and maximise seats.

• Is your space narrower or has multiple door swings?
  → Choose a 3-seater to keep circulation clean.

• Do you host overnight guests in the living room?
  → Consider a corner or 3-seater with sofa-bed function. 

If you’re leaning Corner: what to know (and what to buy)

How to size it

• Common sizes: 260×200, 280×200, 300×200, and full-corner variants. Check left/right orientation vs your door and TV wall.

• Aim for 40–45 cm seat height, 55–60 cm seat depth for lounging; less depth feels neater in compact rooms.

Editor’s picks

• Modern Chesterfield Corner Sofa — classic lines, multiple size options (including 260×200 to 300×200 + full corner). Great for statement living rooms that still need traffic flow.

• Pearl Corner Sofa Bed with Storage — corner comfort plus a sleep solution and hidden storage; ideal for smaller London flats hosting guests. 

• Takumi Corner Automatic Sofa Bed with Chaise — sleek look with an easy convert mechanism for last-minute sleepovers. 

Good to know

• Assembly is included with furniture delivery, so larger corner pieces are handled by our team. (Warranty & care page details assembly coverage.) 

• During Black Friday, large furniture is 35% off + free delivery & assembly — best time to size up. 

If you’re leaning 3-Seater: what to know (and what to buy)

How to size it

• Typical lengths: 200–230 cm. For small rooms, choose slimmer arms and higher legs to feel lighter.

• Pair with a compact accent chair instead of a second sofa to keep walkways clear.

Shop 3-seaters & sofas → [All Sofas & Chairs] (filter by 3-Seater). 

Editor’s picks

• Stara 3 Seater Sofa — soft curves and modern legs; an easy fit in 200–220 cm rooms. 

• Everest 3 Seater Sofa — clean, contemporary silhouette that pairs well with slim media units. 

• Prefer a sleeper? Takumi 3 Seater Automatic Sofa Bed gives you everyday seating + guest-ready function. 

Good to know

• Sofa-beds are brilliant for studios and one-bed flats — check mechanism clearance and mattress size before finalising. Browse our [Sofa Beds]. Atmacha Home And Living

Fabric, colour & custom options (yes, you can match your space)

Most hero sofas come in multiple fabrics/colours, with limited size customisation on select models. For households with kids/pets, choose tighter-weave textiles and book a fabric demo. Visit or call the showroom for swatches and advice. (See product pages and our Black Friday explainer for what’s customisable.) 

Delivery, assembly, warranty — what’s included

• Free UK-wide delivery & assembly on large furniture during Black Friday.

• Our team assembles your furniture on delivery; follow the prep checklist to ensure a smooth route. 

• Structural warranty coverage varies by category (e.g., sofas & armchairs have specific terms). Check each product page’s warranty block.
