SIMPLIFY: A Philosophy to Make prosthesists’ and patients’ life easier.

At ADDDITION, we believe that true innovation is not only about creating new products, but also about simplifying the experience for everyone. With our SIMPLIFY philosophy, we aim to make life easier for both patients and technicians at every stage — from ordering to fitting the final cover.

A Clear and Simple Ordering System

We have designed an easy-to-use order form that allows technicians to request a cover without complicated steps or unnecessary processes. This makes ordering faster, more accurate, and less prone to errors, saving valuable time.

Ultra-Light Covers for Greater Comfort

Our covers are made with extremely lightweight materials to add as little extra weight as possible to the prosthesis. This ensures greater daily comfort and helps patients move naturally without added effort.

No Scans or Photos Required

The process does not require 3D scans or photographs, which significantly reduces the time involved for both technicians and patients. This simplification speeds up the workflow without compromising quality or fit.

Fast Delivery and Easy Fitting

From the moment an order is placed, the manufacturing, delivery, and fitting process is quick and straightforward. Patients receive their covers in less time and can start using them without complications.

Immediate Support for Any Problem

At ADDDITION, we are committed to supporting our customers every step of the way. If any issue arises, our team is ready to provide quick and effective solutions, always with the goal of making life simpler for patients.

Extra Tools for Peace of Mind

Each cover includes knee protectors, extra rubber bands, and a fridge magnet. These additional tools offer greater security and practicality in daily use, making the experience easier and more reassuring for the patient.

Accessible for Everyone

Given our products are medical accessories, in most European countries, our covers are compatible with many national healthcare system codes, which increases accessibility for patients in different economic situations. Personalization and comfort should not be a luxury — they should be available to everyone.


With the SIMPLIFY philosophy, ADDDITION reinforces its commitment to delivering functional, fast, and accessible solutions that genuinely make life easier for amputees and the professionals who support them.

Caring for your cover

A prosthetic cover does much more than improve the appearance of a prosthesis. It also helps protect the internal prosthetic components from everyday wear and tear while creating a more natural and confident look. At Adddition, our prosthetic knee covers are designed for everyday life. They are lightweight, durable, and built to withstand daily use. […]
