Buying a saddle shouldn’t feel like roulette. Joyseat flips the script: instead of guessing your way through widths, shapes, and padding, you start with your anatomy and riding style—and end up with a saddle built around you. Here are 10 things worth knowing before you print your first “ahhh” moment.

A saddle is one of the biggest make-or-break comfort parts on a bike. And if you’ve ever done the saddle carousel—buy, test, suffer, sell, repeat—you know how quickly “just try another one” turns into a hobby you didn’t ask for.

Joyseat was built to end that loop. Not by offering more options on a shelf, but by making one saddle per rider, based on real inputs from your body and the way you ride.

Below are the 10 essentials—what it is, how it’s made, and what makes it different in the real world.

1) Every Joyseat is made for one rider (not a size run)

Joyseat isn’t “small/medium/large” with a few padding choices. Your saddle’s parameters are generated from your inputs—starting with the distance between your sit bones—so the end result is unique to you.

That’s the point: fewer compromises, fewer guesses, more “finally.”

2) You measure at home with the Smiling Butt Kit

Yes, it’s exactly what it sounds like: you make a quick imprint using the Smiling Butt Kit, take a set of photos, and upload them.

That imprint helps determine your sit bone spacing and informs the saddle’s geometry. It’s simple for you, but hugely valuable for getting the fundamentals right—especially width and support placement.

3) The saddle is tuned by a 3S system: Size, Shape, Stiffness

Joyseat customization focuses on three core dimensions:

• Size: width options span 130–170 mm (in 1 mm increments), so you’re not stuck between “close enough” sizes.

• Shape: profiles can shift flatter or more curved depending on your riding style, flexibility, and discipline.

• Stiffness: the 3D lattice can be tuned to support where you need it and soften where you don’t—without turning the whole saddle into one uniform blob.

This is where “custom” becomes more than a label.

4) The padding is industrial 3D-printed from TPU (not poured or foamed)

Joyseat’s padding is produced using Multi Jet Fusion with thermoplastic polyurethane (TPU). In practical terms, that means consistent structure, repeatable quality, and the ability to create complex lattice zones.

It’s also why the feel is different from foam: rather than compressing and packing down uniformly, the lattice acts more like a tuned support system.

5) It’s designed to reduce unnecessary pressure (without making big claims)

Nobody wants numbness, hot spots, or that creeping “I can’t sit another minute” feeling.

Joyseat uses targeted support zones and a pressure-relief approach to help reduce pressure where you don’t want it—especially compared to a one-density foam saddle. Comfort still depends on your full setup (bike fit, shorts, posture), but the goal is clear: support your sit bones, relieve soft-tissue pressure, and keep you stable.

6) The feel can be more “supported” than “cushy”

If you’re coming from a soft foam saddle, Joyseat may feel firmer at first—because it’s designed to hold you in the right place, not let you sink and drift.

Many riders describe the experience as:

• more stable sitting position

• fewer micro-adjustments while pedaling

• comfort that holds up better deeper into the ride

Think “secure and supported,” not “sofa.”

7) It’s built to last longer than typical foam (and it’s modular)

Foam saddles can change character over time as padding compresses. TPU lattice is designed for durability, and Joyseat’s construction is modular—padding + base—so there are long-term options beyond “buy another saddle.”

If your needs change later (or you just want a refreshed feel), the 3D-printed padding can be reprinted while keeping the original base.

8) You can choose the Joyseat model that matches your priorities

All Joyseat variants share the same fully custom 3D-printed padding. The difference is in materials, weight, and compatibility:

• Joyseat Plus: polymer shell + stainless steel rails (7×7 round). Built for durability and broad seatpost compatibility.

• Joyseat Pro: carbon shell + carbon rails (7×9 oval). Lightweight, performance-focused.

• Joyseat Ultra: reinforced UD carbon shell + rails (7×9 oval). Most advanced build for demanding rides.

If you’ve got an integrated seatpost clamp or a seatpost that needs specific “clamps,” pay attention to rail shape (round vs oval).

9) Setup matters more than most people want to admit

Even a perfect saddle can feel wrong if it’s a few millimeters off.

The three big levers:

1. Height

2. Tilt (often a slight nose-down works best for many riders, but don’t overdo it)

3. Fore-aft position

Pro tip: change one variable at a time, and give it a few rides before changing another. Small tweaks can have big effects.

10) There’s a real support system behind the product

Custom shouldn’t feel like a gamble. If something feels off, the next step isn’t “toughen up”—it’s diagnose and adjust.

Joyseat’s support approach typically includes reviewing your setup, suggesting precise changes, and (when appropriate) exploring a padding update rather than starting from scratch.
