jiffy 75 Split Ergonomic Keyboard

Designed to Be Effortlessly Ergonomic

The Jiffy 75 was created to make ergonomic keyboards more accessible.
While our earlier split keyboard, Cornix, helped many users relieve discomfort caused by traditional one-piece keyboards, we learned that highly specialized layouts are not for everyone.

Jiffy 75 bridges that gap—combining ergonomic benefits with a familiar 75% layout that most users already love.

A Familiar Layout, Reimagined

Research shows that the 75% layout is the most preferred configuration among keyboard users.
By splitting this layout, Jiffy 75 helps reduce shoulder tension and wrist strain caused by fixed, narrow typing positions.

The split design also frees up valuable desk space in the center—perfect for tablets, notebooks, or creative tools—enhancing both comfort and productivity.

Full CNC-Machined Aluminum Unibody

Unlike stamped or multi-part cases, the Jiffy 75 is CNC-machined from a single block of aerospace-grade aluminum.
This unibody construction ensures exceptional rigidity, precise internal fit, and long-term durability.

Finished with premium anodization, the surface is smooth, scratch-resistant, and subtly refined.

Ergonomics That Follow Your Body

Traditional keyboards force your wrists and shoulders to adapt.
Jiffy 75 does the opposite.

Its split form allows your arms to rest naturally, maintaining a neutral wrist angle and relaxed shoulder posture.
The calibrated slope and height are carefully tuned to reduce fatigue during long typing sessions.

Stop adapting to your keyboard—let it adapt to you.

Jiffy 75 supports JZF Hub remapping, giving you complete control over your keyboard.

Silent Typing, Refined Feel

Based on user research from the SP75 community, we discovered a strong demand for a quiet typing experience without sacrificing tactile feedback.

To meet this need, we developed a custom 37g silent switch, delivering smooth, low-noise keystrokes—ideal for shared spaces and focused work.
