Custom, Not “Custom-Ish.”

Most 3D-printed saddles offer presets. We combine your sit-bone imprint with details about your body and riding to tailor your saddle’s width, shape and firmness.

Step One: Your Data

12 details about you →

12 inputs describe how you ride and what you need. Together they shape the saddle width, shape, and support — without forcing you into stock sizes.

Plus your sit-bone imprint →

Meet the Smiling Butt Kit. You make a quick imprint at home, send us the photos, and we extract your sit-bone width with 1 mm precision using photogrammetry. Call it input #13. It’s kind of a big deal.

See custom in action: slide your sit-bone width, pick your position, and watch saddle width + pressure map update in real time.

Step Two: Our Algorithm

Size, Shape, Stiffness →

We use parametric modeling. It lets us generate endless precise variations from your inputs — all computed to put support where you need it and take pressure off where you don’t.

Custom is a science →

Your anatomy, riding position and flexibility all help shape your saddle. Watch how different rider profiles translate into different widths, shapes and firmness zones.

Step Three: A Digital Model

A model as unique as you are →

Your saddle becomes a unique 3D model (STL) with our patented mesh. Mesh density, struts, shape, and firmness zones are tuned from your data.

What makes your saddle yours →

Every custom saddle comes with a Saddle Birth Certificate. See the exact data and visuals customers receive with their Joyseat — and how to read them.

Step Four: Custom 3D-Printed Padding

From computer to the physical world →

This is where things take shape. An industrial 3D printer turns ~60 MB of data into ~80 g of custom padding — then it’s checked and paired with the saddle base.

Made to last for years →

Finished by hand with premium European-sourced materials — built to last for years.

Step Five: Time to Ride

Made for you, worth the wait →

A few weeks later, your Joyseat arrives, made around you and the way you ride. Discover why our riders say they’re glad they made the switch.

Forget the saddle, enjoy the ride →

Set up your Joyseat and head out on your favourite route. The next climb, the scenery, the company—give your attention to everything you love about riding.
