About our products

Our prosthetic covers are protective and aesthetic accessories for prosthetic devices that restore the anatomic shape and symmetry of the patient. At the same time, offering a way to express each unique personality and style with different levels of personalization. Made with the latest 3D printing technologies, our covers are available for the majority of lower limb prosthesis and prosthetic components on the market (transtibial, transfemoral, bilateral, osseointegration, etc).

Our covers are easy to put on and off, enabling a smooth access to prosthetic components, providing a cleaner and more hygienic option than silicone or foam covers. It is also a more sustainable solution, as our manufacturing process is zero waste.

Our current offer of prosthetic covers is divided into C-Collection and X-Collection. C-Collection is our signature collection of covers, that are fully customized and designed for each person’s unique anatomy and prosthesis. Each cover is individually designed according to the user’s specific needs, with a selection of colors and designs for both above the knee and below the knee amputees.

The X-Collection is a semi-custom cover, available only for above the knee amputees and selected knees (see our current offer here)

UNYQ covers are easy to identify thanks to the engraved brand logo at the top of every cover, and an individual serial number on the inside. This makes it easy to recognise our product, and simplifies the reordering process.

Apart from personalization and style, all UNYQ covers offer excellent protection for prosthetic components against everyday bumps.They are also water resistant, though the cover does not waterproof internal prosthetic parts, it does shield it from unwanted water exposure and can be used in water activities if you desire. Always ensure your prosthetic is waterproof and can be used for water activities. UNYQ covers are also hygienic and easy to clean.

Our prosthetic covers are waterproof, and can be used in both saltwater and freshwater. Splashes cause no damage to covers. Note: Please, make sure that your prosthetic components are also waterproof.

C-Collection Covers

UNYQ C-Collection Covers are custom-shaped prosthetic covers for lower limb amputees, available for both above (AK/TF) and below the knee (BK/TT) amputees. They offer a new and creative level of protection and personalization for your prosthesis. The end result is a unique, custom-made cover that fits the user perfectly, shows their personality and protects their prosthesis. After printing, each cover is hand polished and painted with a high quality finish to ensure durability. C-Collection covers can be conveniently and easily ordered through your clinic. Only measurements and photos of your lower-limbs are necessary to order. 

The 3D Flex and 3D Firm are two unique materials that we use to create durable and light covers. The 3D Firm is our classic material, made of polyamide (PA12), offering durability and style. The 3D Flex is made from a more rubbery material (TPU), and can endure more manipulations or flexing of its structure. We recommend the 3D Flex to those with a more active lifestyle, as it is more enduring..

C-Collection Firm covers are available for both above the knee and below the knee amputees and are fully customizable. They come in our signature 3D Firm material, available in over 20 designs and over 40 colors in both matte and glossy finish. For further personalization, depending on the model you select, it is possible to add an engraving or vinyl sticker to your cover. To ensure optimal attachment and security, we also offer an additional knee protector, and a choice of attachments between magnets & fast-clamp, or screws & c-clamp. 

Check current designs, colors and extra options that are available for each cover here.

C-Collection Flex covers are fully customized to your anatomy, available for both above the knee and below the knee amputees. They come in our top five designs, in the majority of colors from our chart. For further personalization, you can add an engraving to some of our designs, as well as choose between two attachment types, or add a knee protector (for some designs in AK version).

Check the current designs, colors and available options here.

Our C-Collection covers come in two parts (front and back) and we offer two different attachment systems:

  • Fast-Clamp + Magnets: the front part is attached to the pylon of the prosthesis with our easy fast-clamp system, and the back part is attached to the front part using strong and secure magnets. This solution allows easy access to prosthetic components, so it is easy to clean them, without the need to fully take off the cover. We recommended this attachment for those with electronic knees, as it is easier to charge them..

  • C-Clamp + Screws: the front part includes our C-Clamp system to screw it to the pylon, and the back part is screwed to the front part. We recommend this option for more active users, as it provides even more security.

Each C-Collection cover is designed specifically for every single user’s anatomy and prosthesis, with their unique prosthetic components, combination and alignment. Therefore, our covers may not fit if you change any of the prosthesis’ components, or alignment. Please, ensure the prosthesis and the alignment are completed before taking the photos and measurements when ordering a cover. If you’re changing any of your prosthetic components, or even the alignment of your prosthesis, we recommend you wait until you have your final set up and are comfortable with it before ordering your UNYQ cover.

If you have special requirements, please contact us to learn about the design options and how our covers could integrate with your particular prosthesis. Currently we provide covers for above the knee amputees, below the knee amputees and osso-integrated prosthesis, so contact your clinic, or our sales representatives, and we will be happy to inform and support you in your selection process. 

C-Collection covers can be designed for above the knee and below the knee prosthesis, for most of the prosthetic components in the market.

We also work with osseointegrated prosthesis, both above and below the knee. In this specific case, we need the prosthesis and leg scanned using a structured light scan to adapt our covers..

X-Collection Covers

The X-Collection is UNYQ’s latest addition to its product range. At the moment, It is only available for above the knee prosthesis, in either 3D Firm or 3D Flex. It is the perfect solution for those looking for a quick, no-nonsense protection of their prosthesis whilst enjoying a sleek, classic and elegant design. 

Created in close collaboration with the main providers of prosthetic knees, the X is the perfect introduction to the UNYQ family of products. The delivery time of the X-Collection covers is three days, does not require taking any photos or measurements of the prosthesis, but only needs to be cut to adapt in length by an experienced prosthetist.

X-Collection covers are currently available in our classic U design in black with glossy finish, for a range of the most used prosthetic knees on the market. You can find our current X-Collection covers here. We are expanding the X-Collection offer, so keep an eye out on the website!

​In our X-Collection, the internal part of the cover has been designed specifically to adapt to the prosthetic knee. For securing the front and back part of the cover, we use two pairs of screws for a strong attachment.

Each X-Collection model is specifically designed for a particular prosthetic knee, they are unlikely to fit one they were not designed for. 

Our X-Collection covers are standard products and each model has been designed in just one material based on the characteristics of each knee for a perfect fit and best performance given that they have to adjust perfectly well to every prosthesis leg with that knee. Therefore they cannot be ordered in a different material from the offered one.

For a cover in a different material you can choose a C-Collection cover.

How to order?

Our products can be ordered through our partner prosthetic clinics who are trained in our digital process and fitting. To order a cover, start by scheduling an appointment with your clinician. If you are looking for a customized cover from the C-Collection, it will be necessary to take measurements of your prosthesis and sound leg, as well as pictures of both. If you are interested in a cover from the X-Collection no measurements or pictures are necessary: your prosthetist will adapt the length to your prosthesis in the clinic.

If your clinic is still not on the list, just ask them to here. If your clinic is still not on the list, just ask them to cont​act us and we’ll be happy to train them to order a UNYQ cover for you!.

Many health insurance companies around the world completely, or partly, reimburse prosthetic covers. As each country, region and insurance works in a different way, you can find out the price of the different UNYQ products in your clinic, as well as reimbursement options.

If you already have a C-Collection UNYQ cover, and there has been no change to your prosthetic, or its components, then you may easily reorder by providing your clinic with the serial number engraved inside your cover. Then simply indicate your design choices, and we will replicate the same shape of your current cover in a new style!

However, if you have had any changes to your prosthetic or its components (including alignment), we strongly recommend that you first schedule an appointment with your clinician and retake the necessary pictures and measurements to ensure that the measurements remain the same. Even a slight change may result in an improper fit between the cover and your prosthesis!

If you want to reorder a X-Collection UNYQ cover we don’t need to know the previous serial number, only your current prosthetic knee. Your prosthetist will adapt the length at the clinic.How to reorder a UNYQ cover?

These are the average delivery times for our collections:

  • C-Collection 3D Firm: 2-3 weeks from receiving the correct measurements/pictures
  • C-Collection 3D Flex: 3-4 weeks from receiving the correct measurements/pictures
  • X-Collection: 3-4 days (depending on country) from receiving the order

For the custom C-Collection covers, we send a preview of each personalized design to the specific prosthetist to check the shape and volume of the final product before the printing process. Any extra delay in confirming this preview could affect the final delivery time.

- Taking pictures and measurements through our free UNYQ App (currently available for iOS) that allows you to easily choose the options for the cover, take the information that we need and send them directly to our system.

- Taking pictures and measurements using a camera or any other smartphone. You can find the ordering form and instructions for measurements in our Ordering platform.

- canning the prosthesis and sound leg of the patient, using a structured light 3D scan. For osseointegrated patients, a scan is always required

Recommended scanners:

  • Einstar Scanner
  • Shining 3D Einscan Pro Series Hand Scanners

APP troubleshooting (iOS)

Error description:

When you finish all the steps of the order, the APP starts a progress bar, but it does not end.


Check that you have sufficient coverage on your WIFI network or mobile data card. The ordering process requires uploading a considerable amount of information (including photos), depending on the quality of your connection, it may take a long time to complete.

If you are working with your mobile data plan, try to connect to a WIFI network with a good connection for the best performance.

If you are connected to a WIFI network that does not provide maximum coverage, try using your mobile data plan. Sometimes using the mobile network will give you more speed than a poor WIFI network.

If none of the above options improve the order upload speed, consider improving your infrastructure with WIFI repeaters, a mesh WIFI or some other solution.

Make sure you have enough storage space on your device. The APP needs to compact the photos of your order before sending it, if your terminal does not have enough space, the APP could fail.

Connect your terminal to the mains, especially if you have a low battery. Your Apple device's operating system (iOS) imposes a number of restrictions in certain scenarios when the device has a low battery. We have documented cases in which, for example, the device could unilaterally kill the background image upload process, considering it to require more power than the device should provide in low battery conditions.

Disable power saving options.

If none of the proposed solutions solve your problem, we recommend that you place your order by 3D scanning or following the offline ordering guide; In both cases, you can easily send us your order through our e-commerce or even by email.

Also remember that we will be happy to assist you from Customer Service, where we can guide you through the process or resolve your questions.

Error description:
