Logitech has added three new devices to its Signature series, meant for people who spend long hours at a desk and move between work, personal tasks, and multiple devices throughout the day. It is designed to reduce repeated friction from switching devices, lower input noise, and make long desk sessions more comfortable.
The lineup includes the Signature Comfort Plus M850 L mouse with palm cushion support, the MK880 Signature Comfort Plus keyboard and mouse combo, and the M840 L mouse, which has the same mouse features as the M850 L but without the palm cushion.
These peripherals will be available globally from June 2026 on Logitech’s website and through authorized resellers. The M850 L is priced at $49.99, the M840 L at $39.99, and the MK880 combo at $99.99. Logitech will also sell business versions, with the M850 L for business priced at $59.99 and the MK880 combo for business at $109.99.
What does the new mouse offer?
The M850 L adds a palm cushion along with a sculpted right-hand shape and rubber side grips, giving the hand more support during long use. It also offers silent clicking and scrolling, which should be useful in shared offices or home setups where constant input noise can get distracting.


Logitech has also included its SmartWheel, which lets users move between precise scrolling and faster scrolling. The mouse supports customizable buttons and Actions Ring access through Logi Options+. It can switch between connectivity for up to three devices and offers up to two years of battery life.
The M840 L includes all the above-mentioned features, except the palm cushion.
The keyboard is built for long typing sessions
The MK880 combo adds a full-size keyboard designed around comfort. It has deep cushioned keys, a dual-foam palm rest, curved typing angles, and adjustable typing positions at 0 degrees, 4 degrees, and 8 degrees.

It also supports multi-device connectivity up to three devices and is compatible with Windows, macOS, and ChromeOS. A customizable AI Launch Key can be set up through Logi Options+ to open tools such as Copilot, Gemini, or ChatGPT. Then there is also Logi Tune, which lets users assign functions for Zoom Workplace and Microsoft Teams. The keyboard is spill-resistant and offers up to three years of battery life.
The business versions add a Logi Bolt USB-C secure wireless receiver and support for Logitech Sync, which lets IT teams monitor device and firmware status. These peripherals will be available in graphite, off-white, and black, though availability could vary depending on the region.
