What would you like to do today?

Our pricing model aims to find a balance that enables both a fast sales time and the best possible sales revenue. Mjuk only receives a commission when the furniture is successfully sold.

By selling through Mjuk, you earn 60% of the net sale price up to €700, and 70% of the amount exceeding €700, excluding any pick-up fees if you choose pick-up for your furniture.

The pick-up fee depends on the size category of the furniture: small items €15, medium-sized items €45, and large items €69. Small items are always carryable by one person, whereas large items always require two carriers. Medium-sized items fall between these categories. If you deliver the furniture yourself, the pick-up fee is fully deducted from Mjuk’s share, and you earn the full 60–70% of the net sale price. Pick-up fees are only deducted from the sales revenue, so you do not pay for pick-up separately.

An 11.9% (VAT included) transaction, storage, and insurance fee has been added to the prices shown in the webshop. The price estimate is always given based on the net price of the furniture and the transaction fee does not affect the seller’s proceeds. Of course, you don’t pay anything if, for some reason, your furniture does not get sold, since Mjuk only takes its share from successful sales.

### Frequently asked questions about pricing

#### What is the estimate based on?

The preliminary sale price is estimated based on the condition, age, brand, market price, and demand of the furniture. We also closely monitor specific click counts on our website to determine which types of furniture attract the most interest.

Furniture is always listed for sale at or above the estimated price, except in cases where inspection shows that the furniture is in considerably worse condition than was indicated by the seller’s information.

We always strive to get the best possible price for the items, but the price may be gradually lowered if the furniture does not find a new home at the higher price.

If the condition rating of the product does not decrease during quality inspection, Mjuk will keep the sale price on the website at the estimated price for at least one and a half months, or, correspondingly, at least 9 weeks for premium products.

Our pricing model aims to find a balance that enables both a fast sales time and the best possible sales revenue.

#### Is there a floor price for the item being sold?

Our service is designed so that Mjuk is always in the same boat with the seller. We want the items to sell quickly, but you also get a good price for your furniture.

After publishing the product, Mjuk actively monitors the demand and click rates of specific furniture and may gradually lower the price if the furniture does not sell despite active marketing.

For premium products, the floor price is at most 30% lower than the lower limit of the original price estimate range. Premium products mainly include internationally recognized or unique vintage or design furniture.

Other products with a high resale value may also receive premium classification on a case-by-case basis. Mjuk always notifies the seller separately if the furniture is classified as a premium product.

Mjuk reserves the right, for special situations, to lower the sale price of regular furniture by up to 70% from the original estimate’s lower bound during the process. However, the price is never lowered this far unless the furniture’s condition was significantly worse than expected or it has remained unsold despite active marketing for more than six months.


In this view, you can see your furniture sent for evaluation. The price estimate will appear below once our experts have assessed the products. After accepting the sale, you can choose a suitable pick-up time below. You can also choose to deliver the furniture to our warehouse yourself. Filters can be used to customize the view.

Nomadic tribes in Turkmenistan are known for crafting Torkaman wool rugs—short-pile, hand-knotted rugs characterised by bold borders and a restrained colour palette of deep reds, blacks, and natural whites. Their detailed geometric patterns often symbolise elements of nomadic life, including animals, plants, and stars. Well-known Torkaman styles include Basjir, Salor, Tekke, Tjaudor, and Yomut.

Gabbeh rugs are thick, hand-knotted wool rugs traditionally made by the Persian Lori and Kashghai tribes. They are crafted using both dyed and undyed wool, often featuring shades of beige, red, orange, and deep blue. Each rug is individually handmade, making every piece truly one of a kind.

Malayer rugs are crafted by stitching together pieces of hand-knotted rugs in a patchwork style. They undergo a stone-washing process to achieve a soft, antique look and feel. This method not only repurposes existing materials but also results in distinctive rugs made from traditional Persian textiles.

Kelim rugs are handwoven wool creations made by Persian nomadic tribes. Each one is crafted using traditional techniques, resulting in a unique piece—no two rugs are ever the same. This particular rug showcases the Seneh style, recognised for its classic diamond shapes and intricate herati and boteh patterns. The edges are carefully finished and often richly decorated.

Kelim rugs are handwoven wool rugs traditionally made by Persian nomadic tribes, with each piece being one of a kind. This rug features the Kordi style, characterised by a mix of geometric patterns arranged in horizontal stripes across the surface.

Gabbeh Natural rugs are thick, hand-knotted wool rugs created by the Persian Lori and Kashghai tribes. Crafted from undyed wool, they showcase natural shades of white, grey, and beige. Every rug is handmade, ensuring each piece is entirely unique.

Vintage Royal is a collection of aged, hand-knotted Persian rugs that have been carefully stonewashed and recolored to subtly showcase their original patterns. Owning a Vintage Royal rug means having a unique antique piece crafted by Persian artisans, perfect for adding character to your home.

Tekkeh Kelim rugs are crafted from pieces of vintage Kelim wool rugs, which are stitched together and backed with fabric. This method gives new life to old materials while creating one-of-a-kind, patchwork-style rugs rooted in traditional Persian textile art.

The Abstract series features machine-woven acrylic rugs that resemble wool rugs in texture but offer greater durability and a glossier finish. Perfect for allergy sufferers, acrylic fibres do not release dust. With nature-inspired colours, these rugs bring a calming and balanced vibe to any room.
