How to Choose a Sofa You Will Still Want in Ten Years

Measure the room before you look at anything

Start with three numbers: the wall you will place the sofa against, the depth you can walk past without turning sideways, and the width of every doorway and stair the sofa must travel through. A sofa that cannot make the turn into your living room is a sofa you will return at your own cost.

Then decide the seating depth. Deep sofas look generous in photographs but leave shorter sitters with their feet off the floor. A seat depth of about 53 to 58 cm suits most people; anything past 63 cm is a lounge, not a sofa. If you are furnishing a small room, the constraints in a small living room layout matter more than the sofa itself.

Judge the frame, not the cushion

Ask what the frame is made of. Kiln-dried hardwood, or a hardwood plywood, holds screws and stays square. Softwoods and particleboard are cheaper and will loosen at the joints first. If the seller cannot tell you what the frame is, that is the answer.

Two checks you can do in a showroom: lift one front corner about 15 cm and see whether the opposite corner stays on the floor. If it lifts too, the frame is twisting. Then press down on the front rail; a frame that flexes will click and creak within a year.

Match the fill to how you sit

Foam keeps its shape and needs no attention. Feather and down are soft and need fluffing daily. Most comfortable sofas use foam cores wrapped in fibre or down, which is the compromise worth paying for.

• Sit for ten minutes, not ten seconds. Cushions that feel firm for a minute soften over an hour.
• Ask the foam density. Around 30 kg/m³ and above holds up in daily use.
• Check whether covers unzip. Removable, washable covers add years of life.

Choose fabric for your actual household

Tight weaves resist snags and pet claws better than loose ones. Textured weaves hide marks better than flat ones. Light colours show dirt, but dark colours show lint and fade. A mid-tone textured weave is the forgiving choice.

If you want a light sofa, buy the removable-cover version and wash the covers, rather than spending years covering the sofa with a throw. The same logic applies when you choose a rug size: pick the version you can actually maintain.

Do the four-question test before paying

Can you sit on it for an hour without shifting? Does it fit the room, the door, and the route in? Can the covers be cleaned by you, not a specialist? Would you still want it if the sale ended tomorrow?

If any answer is no, wait. A sofa is a ten-year purchase, and the discount is never worth ten years of a shape that does not suit how you sit. How it combines with everything else in the room is covered in mixing wood tones.
