The core innovation of the Ducky Cushion 98 lies not in simply being “another silent keyboard,” but in its proprietary “Nest Mount” structure—a departure from the “point/line-based” cushioning logic found in conventional Gasket-mounted designs. Instead of relying on edge-placed gaskets, it utilizes a full-surface, suspended silicone or foam pad that “cradles” the internal assembly, ensuring uniform force distribution. Complemented by a tool-free, quick-release top cover and swappable soft/firm cushioning pads, the Cushion 98 transforms the silent keyboard from a “set-it-and-forget-it” device into an adaptable acoustic platform. It is worth noting that this is not a magnetic-switch keyboard; it employs traditional mechanical switches and features a polling/scanning rate of 1000Hz/2kHz, positioning it primarily as a silent mechanical keyboard suited for both office work and gaming.
I. Nest Mount: From “Point Support” to “Surface Support”
In a traditional Gasket-mounted design, silicone strips or foam pads are placed around the perimeter of the mounting plate, concentrating support along the edges. An inherent limitation of this approach is inconsistent typing feel across the board—often resulting in a firmer feel near the edges and a softer feel toward the center (or vice versa).
The Nest Mount in the Cushion 98 shifts this geometric logic. A substantial, elastic silicone or foam pad is positioned beneath the PCB, effectively “cradling” the entire internal assembly. Ducky describes this as a way to “distribute cushioning effects evenly across the entire keyboard,” resulting in a “more consistent typing feel” compared to standard Gasket designs. A teardown by the review outlet Club386 offers further detail: “Beneath the switches and PCB, you’ll find a thick, flexible silicone cushion—what Ducky calls the ‘Nest Mount’—which acts like a suspension system, evening out the impact from each keystroke.”
The engineering benefit of this “surface support” is consistent key response. Regardless of where your fingers land on the keyboard, the depth of the internal assembly’s downward travel and the force of its rebound remain remarkably uniform. The trade-off is a “softer” typing feel—reviewers at Club386 noted that the pre-installed black dampening pad “provides the quietest experience” but feels “a bit mushy.” Swapping it for the gray pad results in a “firmer, less mushy” feel, though it is not quite as quiet as the black one.
II. Interchangeable Dampening Layers: Making “Sound Tuning” User-Accessible
The most distinctive design feature of the Cushion 98 is its tool-free, quick-release top cover, paired with two swappable dampening pads.
The top cover is crafted from CNC-machined aluminum and secured by rear clips and front magnets, allowing it to be removed without a screwdriver. Once opened, users can simply slide out the dampening pad located beneath the PCB and replace it with the other option. The package includes two pads: a black one (pre-installed; softer and quieter) and a gray one (firmer, offering a more solid feel). As described on the Caseking product page, the pre-installed layer is softer, while the additional layer is firmer, allowing users to tailor the typing experience to their personal preferences.
The significance of this design lies in the fact that preferences for the feel of a silent keyboard are highly subjective. Some users may desire a “cloud-like” softness, while others might prefer a “resilient, supportive” feel. Most silent keyboards are fixed in their configuration from the factory, leaving users with a “take it or leave it” scenario. The Cushion 98 puts the choice back in the user’s hands, with a very low barrier to entry—no soldering or unscrewing required; the entire process can be completed by hand in just two minutes.
III. “Shush” Switches and Acoustic Objectives
The Cushion 98 comes equipped with Ducky’s proprietary “Shush” silent switches, available in both linear (Shush Red) and tactile (Shush Green) variants. The switches are factory-lubricated and support hot-swapping. In terms of specifications, the Shush Green (tactile) switch features an actuation force of 45gf, an actuation travel of 2mm, a total travel of 4mm, and a bottom-out force of 55gf; the Shush Red (linear) switch has an actuation force of 43gf, an actuation travel of 1.9mm, and a total travel of 4mm. The core selling point for both is “low noise”—the switches incorporate internal dampening to suppress sounds during bottom-out and rebound, while the tactile (Green) version retains a perceptible tactile response.
Acoustically, the Cushion 98 does not aim for total silence, but rather a “deep, thuddy, and non-piercing” sound profile. The thick “Nest Mount” cushioning absorbs the high-frequency components of the impact when keys bottom out, while the internal dampening within the Shush switches further suppresses any extraneous mechanical noise. In a hands-on review at Computex 2025, TweakTown described the experience as “quiet and cushioned, yet still responsive”—avoiding the “mushy” feel often associated with non-mechanical keyboards.
IV. Configuration and Positioning: A “Versatile” Mechanical Keyboard Prioritizing Silence
The Cushion 98 utilizes a compact 100-key layout; it retains a number pad while maintaining a footprint similar to a TKL (tenkeyless) board, leaving more desk space for mouse movement. It offers tri-mode connectivity (USB-C, 2.4GHz, and Bluetooth), with a 1000Hz polling rate in wired/2.4GHz modes and an internal scan rate of 2kHz. It is equipped with a 4200mAh battery, rated for 63 hours of use with the backlighting turned off.
Structurally, the top case is made of aluminum alloy (sources vary slightly on whether it is CNC-machined or stamped), while the bottom case is ABS plastic. It features PBT double-shot keycaps in the “Cherry” profile, with south-facing RGB lighting. The stabilizers are plate-mounted. Software support includes the DuckyHub web-based interface and VIA, eliminating the need to install a desktop client.
One notable detail: the Cushion 98 is not a magnetic-switch (Hall-effect) keyboard. It lacks Rapid Trigger (RT), adjustable actuation points, and an 8K polling rate. Ducky’s technical focus for this product lies in structural acoustics (“Nest Mount”) and silent switches (“Shush”), rather than the competitive specifications typically associated with magnetic-switch keyboards. It is designed for users who need a quiet mechanical keyboard with a customizable feel—one suitable for both office work and gaming—rather than for FPS players who demand 0.01mm RT precision.
V. Boundaries and Trade-offs
The design trade-offs of the Cushion 98 are clear.
Silence takes precedence over tactile feedback. The “soft, cushioned” sensation provided by the pre-installed black dampening pads is the price paid for silence. If a user desires a firmer bottom-out feel, they must sacrifice some of that silence by switching to the gray pads; you cannot have both.
Mechanical switches instead of magnetic ones. In 2026—a time when magnetic-switch keyboards are becoming increasingly widespread—the Cushion 98 opts for a traditional mechanical switch architecture. Its competitive edge stems from the combination of the “Nest Mount” system and “Shush” switches, rather than adjustable actuation or ultra-high polling rates. For competitive gamers already accustomed to the Rapid Trigger (RT) functionality of magnetic-switch keyboards, the Cushion 98 is not directly comparable.
Weight and portability. The unit weighs approximately 1216g. While the aluminum top cover provides a premium feel and structural rigidity, it also means the keyboard is better suited for a stationary desktop setup than for frequent transport.
