Good sofas deserve a second home.
Sofakontor is the shop for pre-owned designer sofas by Aaron GmbH. We buy selected sofas in very good condition, inspect them in eight stations and pass them on with a 12-month warranty – from Hamburg and Cologne to anywhere in Germany.

What we do
One sofa, three steps – all from a single source, with no middlemen.
Buying
We buy selected designer sofas in very good condition – from non-smoking, pet-free homes and from showrooms. Fairly valued, handled without fuss.
Inspecting
Every sofa goes through our eight stations – from the purchase inspection to the final inspection with an inspection report.
Passing on
Online, in our Hamburg showroom or our Cologne warehouse – with delivery or collection and a 12-month warranty.
From Aachen to Hamburg and Cologne
-
Aachen
This is where it all began – with the idea of passing on high-quality designer furniture in an affordable and sustainable way.
-
2021
Next comes our warehouse in Hamburg.
-
2023
Our Cologne warehouse is added – for shorter delivery routes.
-
Today
Aaron becomes Sofakontor: same team, same standards, new name.
Eight stations. Every sofa is inspected.
Our logo has nine squares: eight for the stations and a red one in the middle. A sofa only earns that one once it has passed every station that applies to its material – then it goes on sale with an inspection report.
-
Purchase inspection
Good sofas start at the buying stage. We buy selectively: only from non-smoking, pet-free homes and only originals in very good condition. We check the model, origin and condition before we commit.
-
Incoming inspection
In our warehouse we check the frame, joints, suspension, fittings and all adjustable functions for stability, wear and function. We also record the manufacturer's labels and the dimensions.
-
Material analysis
We assess seating comfort, shape retention, padding, seams and upholstery and identify the material. Then we decide which cleaning and care the piece receives.
-
Spray extraction
We clean fabric covers and upholstery using spray extraction, adapted to the material and weave: the cleaning solution is worked deep into the fibre and immediately extracted again. Suitable stains are treated in a targeted way, as far as the material allows. For leather sofas, this step does not apply.
-
Leather care
We clean leather gently with specialist cleaners, replenish its oils and protect the surface with a sealant. Areas showing wear receive targeted care, as far as the leather and its condition allow. For fabric sofas, this step does not apply.
-
Ozone treatment
We check every piece for noticeable odours. It then goes into a closed room where ozone penetrates the entire upholstery and neutralises odours even where no cleaning can reach.
-
Function test
We refit removable parts and test the frame, suspension and joints under load. Every mechanism is run through all positions several times: recliner, sleeping and adjustment functions. Only what runs smoothly and cleanly moves on.
-
Final inspection
Finally, we check appearance, cleanliness, odour, seating comfort and function a second time. We photograph the piece from all sides, show signs of use openly and only then release it for sale.
What we stand for
Fair price
The price is based on the condition of each individual sofa – and is always shown next to the RRP.
Sustainability
Every sofa that finds a second home is one that doesn't need to be newly produced.
Longevity
Over the years, we've learned which brands and materials really last.
Happy customers
Thousands of customers have already bought from us. That's what we measure ourselves by – and we take time for every question.
Quality
Eight stations and a 12-month warranty for every sofa.
In person
Try it out in Hamburg or Cologne by appointment – or let us show you the piece by video call.
