Ordering and Manufacturing Joyseat Step by Step

"This is too narrow, that's too wide, this one's too hard, and that one's too soft, and that one just looks weird." In today's market, it's increasingly challenging to find the perfect cycling saddle that precisely meets your needs. That's why we at Posedla have decided to flip the manufacturing and buying process on its head. Instead of sifting through an endless array of saddles and hoping to find the right one, we'll make one tailor-made just for you, according to your specifications.

Behind the development of Joyseat are thousands of hours at the computer and in the saddle, dozens of test riders, countless prototypes, and months of work from experts in bike fitting, biomechanics, photogrammetry, and computational design. We've done the hard work; now, it's your turn to enjoy the ride. You can shorten the time between ordering on our website and receiving your custom saddle by learning about the journey Joyseat takes before it gets to you.

Ordering and Uploading Photos and Data into the Configurator

Getting the Joyseat custom saddle is so simple that you can't go wrong. Just choose your bike type (road, gravel, MTB), add it to your cart, and make your payment. Within a few days, our measuring "Smiling Butt Kit'' will arrive at your provided address. Thanks to this kit, we can precisely determine the width of your sit bones. This measurement is crucial for the final width of your saddle. How do we do it? You'll take an impression of your behind using the Smiling Butt Kit (instructions here), snap a few photos of the imprint, and upload it to our website's configurator. In the configurator, you'll also set your saddle parameters (stiffness, longitudinal and transverse curvature, padding thickness, width) by answering simple questions. That's it! The faster you complete this, the sooner we can start making your custom saddle.

JoyFit Algorithm and 3D Model Creation

Now, we take the baton – specifically, our JoyFit Algorithm. It processes all your input data, identifies the lowest points in the imprint, measures the exact distance between your sit bones, and then designs a saddle tailored precisely to your needs. We'll double-check this design, compare it with your notes on your favorite saddle types and shapes, and email you the sit bone spacing we measured. Simultaneously, we send the 3D printing data to production.

3D Printing Technology and German Quality

The production of our unique 3D padding takes place in Germany, where our partners use HP Multi Jet Fusion printers with TPU (thermoplastic polyurethane) powder, sourced from BASF. This sets us apart from other manufacturers of prefabricated 3D-printed saddles, which use a flexible structure made from liquid polymer cured with UV light. We create our flexible structure through an even distribution of infrared light and heat in the printing chambers, resulting in a stronger and more durable polymer structure. In practice, this means we can print saddles in various shapes and even add inscriptions with an accuracy of 0.22 millimeters. This ensures that your Joyseat fits you like a glove.


TPU is fully recyclable and reusable without losing its quality. Our 3D printing technology allows us to use up to 80% recycled powder material, minimizing the creation of new waste.

Shell and Rails from Northern Bohemia

While the 3D printer in Germany is working at full speed, our master craftsmen in Varnsdorf, in the heart of the Lusatian Mountains, are handcrafting the carbon shell and rails. We manufacture these carbon saddle parts right here in the north of the Czech Republic. Quality, stiffness, and lightness – these are the attributes that carbon fiber production offers. Our experienced operators carefully layer carbon fibers onto molds to ensure maximum strength. This is followed by an 11-hour heat curing process. We take quality seriously, which is why each Joyseat saddle must pass through several hands to ensure it's perfect.

Assembly and Saddle Dispatch

After thorough inspection, the saddle moves on to other specialists who sand it, glue it, and assemble it. We use glue on four contact points, allowing us to expertly replace the top 3D-printed layer if needed. Both at our supplier's location and in Varnsdorf, strict quality control of the 3D padding takes place, checking its visual aspects and the stiffness of individual parts. If we are satisfied with the result, we lovingly package your Joyseat in recycled materials (no plastic here) and prepare it for shipment. You'll receive a tracking code via email, and in a few days, your saddle will be delivered to your doorstep by the mail carrier.

Our Philosophy: Quality, Local & Custom Manufacturing

Our philosophy is simple: we want to create custom saddles that fit perfectly and enhance your riding experience. That's why we don't follow the path of massive warehouses full of prefabricated saddles. Instead, we start production only after receiving an order, ensuring that each saddle is uniquely tailored to the customer's needs.

Whether you're a roadie, gravel shredder, mountain biker, or just commuting to work, Joyseat will provide comfort in all situations – it won't press where it shouldn't and will support where it should. Our exceptional customer service is available to you even after the saddle is delivered – you can count on us if anything doesn't feel right.

We're also proud to produce the maximum possible portion of our products locally in Varnsdorf, where we come from. We employ processes that minimize waste and use natural resources responsibly.
