A custom couch, what you're actually paying for

Summary: A custom couch costs more because the frame, foam, fabric, upholstery labour, overhead, and lead time all stack up. The right reason to pay for one is usually fit: an awkward wall, radiator, stairwell, or module size that standard sofas cannot handle.

A friend asked me last month why a "custom couch" quote came back at 6,800 euros when the IKEA equivalent was 1,200. She'd sent the same photo and floor plan to three Amsterdam upholsterers. The lowest quote was 6,200. The highest was 9,400. She wanted to know if she was being fleeced or if that's just what custom costs.

The honest answer is: a bit of both, depending on the shop. But mostly the second thing. Custom sofas are expensive for reasons that aren't always obvious from the quote PDF, and the price gap between a good shop and a bad one is smaller than the gap between custom and off-the-shelf. Here's what's actually inside that number.

The wall is rarely a friendly size

Off-the-shelf sofa lengths cluster around a few standard dimensions. 1.8 m, 2 m, 2.2 m, sometimes 2.4 m. If your wall is 2.15 m, you've got a problem. Either you live with a 5 cm gap that catches dust and looks like a mistake, or you push the next size down off-center, or you spend six weeks on a custom build.

My friend's wall was 2.46 m with a radiator clipping the right side. The radiator stuck out 9.2 cm from the wall plane. Any standard sofa pushed against that wall would either leave a comically large gap or sit on the radiator. So she wasn't really shopping for a custom couch out of luxury. She was shopping for one because the room had decided for her.

This is the boring origin story for most custom sofa orders. Not a desire for handmade craftsmanship. A bad wall.

The frame is maybe a quarter of the cost

A sofa frame is a wooden skeleton. Kiln-dried hardwood (usually beech, oak, or birch ply) cut into pieces and joined with corner blocks, dowels, and screws. A reasonable frame for a 2.4 m three-seater uses something like 14 to 18 kg of timber and takes a competent shop maybe four to six hours to build. The materials run 180 to 300 euros depending on species and waste.

So the frame for a 6,800 euro couch is in the range of 600 to 900 euros total, including labor.

What's the rest of the money doing?

Foam, springs, and the bit you sit on

Below the cushion you've got a suspension system: webbing straps, sinuous springs, or a pocket-spring deck. Above it you've got the cushions, which are usually high-density polyurethane foam wrapped in a polyester or feather topper, then a fabric cover.

Decent foam (high-density, the kind that doesn't go pancake in two years) costs roughly 60 to 90 euros per cushion in materials. Springs and webbing for a three-seater run another 120 to 180. Add labor for cutting, gluing, and tufting and the seating layer is 700 to 1,100 euros.

The fabric is where things get wild. A boucle from a mid-tier mill is around 70 euros per linear metre. A three-seater eats 14 to 18 metres of fabric depending on pattern matching and arms. So that's 1,000 to 1,300 euros in cloth alone. Velvet, linen, performance weaves: same range, give or take. Top-end fabrics from Romo or Dedar can double it.

The upholstery labor itself, the actual hand-stretching and stapling and seam-matching, is the big one. A skilled upholsterer takes 18 to 30 hours on a three-seater. At 55 to 75 euros an hour, that's 1,000 to 2,250 in labor.

Add it up: frame, suspension, foam, fabric, upholstery labor. Materials and direct labor on a 2.4 m custom couch land somewhere between 3,000 and 4,500 euros. The rest of the quote, the bit between 4,500 and 7,000, is shop overhead, design time, delivery, and margin.

Where the quotes actually diverge

Three shops quoting on the same brief will come back with prices that differ by a factor of two. That sounds like one of them is robbing you. Usually they're just running different businesses.

A small workshop with two people and a rented arch under the railway tracks has overhead of a few thousand a month and quotes accordingly. A showroom in a nice neighbourhood with a designer on staff and a markup on every roll of fabric runs ten times the overhead and quotes accordingly. Neither is wrong. They're selling different things.

The questions to ask, in order:

• What species and dimensions is the frame? Get this in writing.
• Foam density, in kg/m³ or lb/ft³. Anything below 35 kg/m³ is going to sag.
• How many metres of fabric are you ordering for my couch, and what's the per-metre price?
• Is the fabric included or quoted separately? (Most shops quote separately, which makes comparing prices a nightmare.)
• Lead time, in weeks, with a written delivery window not a month.

If a shop won't answer those, that's the answer.

The lead-time problem

Custom sofas take time. Six to twelve weeks from order to delivery is normal. Some shops will quote four weeks and miss it. Some will quote sixteen and hit it on week ten.

The longest part isn't the building. It's the queue. A workshop with three upholsterers can build maybe twelve to fifteen couches a month. If you walk in with seven couches in front of yours, you're waiting eight weeks before they even cut your frame.

Ask where you sit in the queue. Ask if they'll send a photo when your frame is built. If the shop can't say either, factor in another two weeks of slip.

The middle path most people don't know about

You don't always need to choose between IKEA and a 6,800 euro full custom build. There's a middle option that gets discussed less than it should.

You can buy a custom-cut frame, a flat-pack one, designed to your wall dimensions and shipped pre-cut to size. Then you buy off-the-shelf cushions sized to fit. You assemble the frame yourself with dowels and a hex key. The fabric goes on as a slipcover. Total cost, for a 2.4 m three-seater, lands around 1,400 to 2,200 euros all in. It's not as plush as a sprung-down full custom, but it fits the wall and it doesn't take twelve weeks.

The trade-off is mostly comfort. A flat-pack frame with a slipcover is firmer and a little less forgiving than a hand-tied custom. For a guest room or a second couch it's perfect. For the main living-room couch you sit on every evening, you might still want the full custom job.
