With the new Joyseat series, Czech saddle expert Posedla is launching three innovative models for customised bicycle saddles. The Joyseat Plus, Joyseat Pro and Joyseat Ultra models are designed to make the proven technology of customised 3D printed saddles accessible to a wider audience. All three models are based on multi-jet fusion 3D printing technology in combination with Posedla's proprietary 3S algorithm. This adapts the size, shape and stiffness of the saddle to the biker's individual biometric data and riding style. We have already extensively tested the Posedla Joyseat 2.0 - and evaluated the driving impression as well as the ordering procedure.
Customisation as a basic principle
According to Posedla, customisation is not just a feature, but the foundation of the new Joyseat series. The data for saddle customisation is recorded conveniently at home using the so-called Smiling Butt Kit - an innovative set for taking impressions of the sit bones. The saddle is then fine-tuned based on various parameters such as area of use, training volume, flexibility and gender. The result is a customised saddle that can vary in 1 millimetre increments between 130 and 170 millimetres in width. The shape and stiffness are adapted to the cyclist's anatomy, riding style and discipline. There is a choice of versions for road bikes, gravel bikes, mountain bikes and time trials.
Posedla Joyseat Plus - entry-level model with high compatibility
With the Joyseat Plus, Posedla wants to make its high-performance saddle technology accessible to a wider audience. The saddle is characterised by a lower price, a higher permissible rider weight of 120 kilograms and industry-standard fastenings, according to the manufacturer. The combination of a polymer shell and stainless steel stays enables the lower price with improved durability and compatibility.
The glass fibre reinforced plastic shell has been specially selected for its toughness and mechanical strength. The 7x7 millimetre round stainless steel stays ensure compatibility with all standard saddle clamps. The 3D-printed thermoplastic polyurethane (TPU) padding is used throughout the Posedla range.

Posedla Joyseat Pro - Lightweight carbon flagship
The Joyseat Pro takes over the role of the premium carbon fibre saddle from its predecessor, the Joyseat 2.0. With a twill carbon shell and unidirectional (UD) carbon stays, it offers a lightweight construction with a customised fit. Since the introduction of the previous model, Posedla has continuously refined every element of the saddle design through a combination of testing, research and customer feedback.
The ergonomic improvements include a more anatomically contoured shape and a narrower nose for improved thigh clearance and better overall support. The structure of the saddle has also been optimised, with a refined grid density of the padding and an improved carbon base, which should increase both durability and responsiveness.

- Bowl material: Twill carbon
- Material struts: Unidirectional carbon
- Upholstery: 3D-printed thermoplastic polyurethane (TPU)
- Weight: from 165 g

Posedla Joyseat Ultra - Maximum rigidity for demanding applications
The Joyseat Ultra is said to be the most technologically advanced saddle in the Posedla portfolio. It uses the company's research results in the field of carbon fibre layer construction technology and is designed to offer optimum strength and stiffness under the most demanding conditions. It is made from a reinforced UD carbon fibre shell and struts. Without any increase in weight compared to the Pro model, according to Posedla.
