Ergo K860 Keyboard

The Ergo K860 Keyboard from Logitech features a flowing design that orients keys at varying angles across the keyboard. The K860 alpha/numeric keys transition through a concave arc from almost level at the centre to about 5° at the right and left edges. The navigation cluster on the right then completes the transition to a fully flat numeric keypad. The left and right key groups are also angled or "splayed" outward to encourage adoption of a more neutral alignment of the wrists. The Ergo K860 also has an attached 3.5" deep cushioned palm support which rises up to match the keyboard elevation. This needs to be taken into consideration when deploying the K860 into a workstation.

While the K860 has a slender low profile the angled design results in the middle keys being elevated to 1.5". This elevation may require individuals to either raise their seats to accommodate the height of the keyboard or to use a keyboard tray to lower the keyboard into their lap. The keyboard is also equipped with front legs that can be used to raise the front to create either 4° or 7° negative slope intended to encourage better wrist alignment. Use of these legs may require further adjustments of seat or keyboard tray height because it adds another inch of elevation to the middle of the palm support and increases the risk of pressure points being created on the underside of the wrists.

The K860 features low-travel scissor switches with chiclet-style keycaps. Key activation is crisp and comparatively high force compared to other scissor switch devices and does require a significant degree of activation force. The low profile keycaps have a satin texture with a slight concave surface to aid in finger positioning.

• Preset Fixed "Splay": The keys are arranged with a limited preset degree of splay to help reduce ulnar deviation.
• Partially "Tented" Arc Design: The keycaps transition through a mostly convex arc from about 2° on the innermost column down to approximately 4° on the outermost column of alphanumeric keys. The navigation keys then continue the transition down to a flat numeric keypad.
• Negative Inclination Legs (4° & 7°): These legs can be used to elevate the front edge of the keyboard to create "negative inclination". (see notes in Usage Tips)
  NOTE: The palm support itself is NOT removable and elevates with the legs.
• Permanent Integrated Palm Support: The Ergo K860 Keyboard incorporates a fairly deep (3.5") lightly padded palm support. This support also arcs upwards to 1.5" in the middle so the palms will be lifted. The reaching distance to the keys and the elevation of the palms need to be carefully considered when determining the ergonomic suitability of this keyboard. Please see the Usage Tips section for further discussion of these concerns.
• Cushioned Comfort: The integrated palm support offers layers of high density and memory foam to provide both support and comfort. It is covered by a durable knitted fabric treated with a smooth stain-resistant and easy-clean coating.
• DUAL Connection Cordless Convenience: The Ergo K860 can connect either via Bluetooth or through the included micro-receiver. The keyboard can be paired with up to 3 devices, each easily accessed via their dedicated connection keys.
• Long Battery Life: Logitech states that two AAA batteries are able to power the keyboard for up to two years. The battery indicator will provide notification when battery replacement is required.
• Windows and Mac Ready: Dual Legending with optional software to support customized use in both environments.
• Programmability and Customization: The Logi Options+ app (Windows and Mac options) can be downloaded to accommodate personalization of the keyboard functions.

• The central elevation of the palm support (even when the negative inclination legs are not deployed) may force you to hunch your shoulders or move the keyboard away so you can reach forward without hunching. Either of these will force you to a adopt a non-ergonomic posture that may lead to discomfort or possibly long-term musculoskeletal damage.
• The negative inclination legs that this keyboard is equipped with create a negative slope that is generally considered a desirable feature. However this can be a potential concern because the front edge of the keyboard is now elevated. This elevation increases the potential for the edge of the keyboard palm rest to come in contact with the underside of the wrists, creating a potential pressure point. This would be more of a concern for those with smaller hands. The only ways to address this are by either elevating the chair to compensate for this increase in height (which may request additional adjustments to the workstation) or by lowering the keyboard tray (if used) to where it is sitting directly on the lap. However, this does not address that fact that a height differential will now exist between keyboard and mouse, a factor that should be considered when deciding whether this is a suitable keyboard. Deploying the negative tilt legs can lead to individuals now having to reach "up and down" as well as potentially too far to the right whenever transitioning between mouse and keyboard.
• The rather significant 3.5" depth of the permanently affixed palm rest can potentially move this keyboard too far away from those of smaller build, forcing them to "reach forward" to access the keys. This can put unnecessary strain on the shoulders as the arms are no longer able to hang in a neutral position with the elbows below the shoulders.
• Our recommendation is that the Ergo K860 be used either on a keyboard tray where the tray is able to be lowered right to the legs or on a height-adjustable desk that can be lowered to provide similar positioning. In this position the shoulders will be able to remain relaxed, with the elbows hanging directly below them. This will also aid in positioning your hands in alignment to the splay of the alpha/numeric keys.
  Note: If a sit-stand desk is lowered to better position the keyboard to achieve optimal positioning an increase in monitor height may be required due to the desk surface being lower).
• Caution should be exercised when using the Ergo K860 Keyboard with a mouse placed on the right side of the keyboard. Although not as large a reach as some other keyboards, The K860 still requires a reach of at least 10" from the home row "J" to the right edge of the keyboard). For many typists, especially those of smaller frame or with narrower shoulders, this will result in "over-reaching" outside of the Comfort Zone.
