The couple who can't agree
She wants green velvet, he wants leather. Two pictures of their own living room with each sofa, and the choice comes down to what they see rather than what each of them imagined.
Swap the sofa in a photo of your living room with AI
A photo of your living room with an emerald velvet sofa, then a cognac leather one, same spot, same size. Decide before the showroom. Workflow visible here, no account needed.
Real workflow: a bright living room with a three-seater, a loveseat, a white rug and a round coffee table, then the same room with both sofas in emerald green velvet and in cognac leather. Pictures, plant, floor lamp and sideboard stay in place.

A sofa gets bought in a showroom, among fifty others, under lighting nothing like your living room. The emerald that looked great in the shop turns overpowering at home, or the cognac clashes with the floor. This workflow starts from a photo of YOUR living room and swaps the sofa for two models, green velvet and cognac leather, in the same spot.
The hard part is changing only the sofa. Left alone, an image model redoes the rug, moves the coffee table or shifts the light, and the comparison is worthless. The prompt describes the new sofa and lists everything that stays. Flux Kontext replaces the object and keeps the room.
To try a different wall colour behind it, follow up with the paint colour test; for a piece you're keeping, with the furniture makeover. Both sofas cost twelve credits.

Who it is for
People replacing a sofa, furniture salespeople showing a model in the customer's home, interior designers.
Which files to provide
A photo of the living room with the whole sofa, and the model you want: seats, material, colour, arms, legs.
How it works
- 1
Photograph the living room
Straight on, the whole sofa in frame, with what surrounds it: rug, coffee table, wall. Daylight, no flash.
- 2
Describe the new sofa
Number of seats, material, exact colour, arm shape, legs. "A green sofa" lets the model decide everything else.
- 3
Say which one to replace
With two sofas or a matching armchair, be specific: both, or only the big one on the left. In the demo, Kontext changed both.
- 4
Compare in your own light
Look at the two pictures at the time of day you actually use the room, then go and see the fabric or leather in person before ordering.
Variations and use cases
The same canvas, tuned for different needs: each variation is two or three lines of prompt away.
The furniture salesperson
In the showroom, the salesperson asks for a photo of the customer's living room and shows the floor model, in the chosen colour, in their home. The customer leaves with a picture instead of a doubt.
The furnished rental
A landlord who lets a furnished flat wants to freshen up the lounge before reshooting the listing. He compares two sofas on the room photo, buys the right one and only books one photo session.
The interior designer
She puts together a board for her client: the room as it is, then with two sofas in the project's colours. The client signs off on a style before heading to the shops.
The old sofa to reupholster
Before paying an upholsterer, the owner tries several covers on the same three-seater in the photo: velvet, linen, leather. She walks into the workshop with the material already chosen.
The student studio
Not much space, one sofa that doubles as a spare bed. The student checks that a cognac model won't make the room feel too dark before spending a year's furniture budget on it.
Common mistakes
Forgetting what should stay
Without "same rug, same coffee table, same curtains", the model may retouch the whole seating area. The end of the prompt matters as much as the start.
Not saying which sofa
With two sofas in the room, "replace the sofa" is ambiguous. In the demo, both changed. Say which one, or both.
Missing a detail
On the demo's velvet sofa, the brass legs asked for came out as light wood. Check the details that matter to you and run it again if needed.
Judging size from the picture
The sofa is at a believable scale, not to your measurements. Measure the wall and the doorways before ordering.

GPT Image 2.5 SunburstFrequently asked questions
Does the rest of the room change?
No: same walls, same window and sheers, same rug, same coffee table, same pictures. Only the sofas are replaced.
Can I try a corner sofa instead of a straight one?
Yes, if there's room for it in the photo: describe "corner sofa, return on the right". The model keeps the room's scale, not your exact measurements.
Does it work with a model I saw in a shop?
This template works from a description, not a product photo. Describe its arms, legs, material and colour as precisely as you can.
How much do the two renders cost?
Twelve credits, six per render on Flux Kontext. A third sofa on the same photo costs six more.
Why Flux Kontext?
Because it replaces an object in a photo without repainting the rest: in the demo, pictures, plant, floor lamp, sideboard and rug all stayed where they were.
Can I keep the loveseat and change only the big sofa?
Yes: write "replace only the three-seater sofa on the left, keep the loveseat as it is". Without that, the demo shows both get changed.
Are the colours accurate?
They give a good sense of the overall look, not the exact shade of a catalogue fabric. Ask for a swatch before ordering.
What output format?
The format of your photo, here 4:3. A living room photographs well in landscape, from the doorway.
