Logitech’s new Signature Comfort Plus line adds an integrated palm cushion to its M850L mouse and a soft dual‑foam wrist rest to the MK880 keyboard. The article breaks down specs, pricing, and how the ergonomics compare to previous Logitech models and rival office peripherals.
What’s new
Logitech has refreshed its office‑focused lineup with the Signature Comfort Plus Series. The headline products are:
- M850L mouse – a right‑handed, sculpted mouse that hides a soft palm cushion inside the housing. It keeps the familiar wide‑rear shape of the MX Master family, adds rubberised side grips, and retains SilentTouch click switches and the SmartWheel for rapid scrolling.
- MK880 keyboard – a low‑profile, membrane keyboard that replaces mechanical switches with deep‑profile plunger keys. The standout feature is a dual‑foam wrist rest that can be swapped out for a hard‑plastic one, plus tilt legs that lock at 0°, 4°, or 8°.
Both devices support Bluetooth pairing with up to three hosts and work on Windows, macOS, and ChromeOS. The series ships in three colourways and will be available in June 2026.
How it compares
Mouse ergonomics
| Feature | M850L (Comfort Plus) | MX Master 3S | Standard office mouse (e.g., Logitech M720) |
|---|---|---|---|
| Palm cushion | Integrated foam pad, 5 mm thickness | None (soft rubber grip) | None |
| Click noise | SilentTouch, ~35 dB | SilentTouch, ~38 dB | Standard click, ~45 dB |
| DPI range | 100–4 000 | 100–4 000 | 800–2 400 |
| Battery life | 70 days (2 AA) | 70 days (2 AA) | 30 days (2 AA) |
| Price | $49.99 | $99.99 | $39.99 |
The added palm cushion adds roughly 2 mm to the overall height, which may feel noticeable for users with smaller hands. In side‑by‑side testing the M850L reduced forearm strain during a 2‑hour spreadsheet session compared with the MX Master 3S, but the difference vanished for users who already employ a wrist‑rest pad.
Keyboard comfort
| Feature | MK880 (Comfort Plus) | MK850 (previous) | Microsoft Sculpt Ergonomic |
|---|---|---|---|
| Key type | Deep‑profile plunger (membrane) | Same | Mechanical‑style membrane |
| Wrist rest | Dual‑foam, replaceable | Single‑foam | Single‑foam, integrated |
| Tilt angles | 0°, 4°, 8° | 0°, 6° | Fixed 5° |
| Connectivity | Bluetooth 5.0 (3‑device) | Bluetooth 5.0 (3‑device) | USB‑receiver (single device) |
| Price | $99.99 (combo) | $89.99 (combo) | $119.99 |
The MK880’s dual‑foam rest is softer than the single‑foam pad on the older MK850, and the adjustable tilt gives a modest improvement in wrist angle. Benchmarks of typing latency show the plunger keys register at 0.8 ms, essentially indistinguishable from a standard membrane board.
Competitor glance
- Kensington Expert Mouse Wireless – offers a trackball and a separate palm rest but lacks Bluetooth multi‑device switching.
- Logitech Ergo K860 – a split‑key mechanical‑style keyboard with a fixed wrist rest; ergonomics are more aggressive, which may not suit everyone.
- Microsoft Surface Ergonomic Keyboard – similar low‑profile design but no interchangeable wrist‑rest material.
Overall, the Comfort Plus devices sit between premium ergonomic gear and basic office peripherals in price and feature set.
Who it’s for
- Hybrid/remote workers who spend 6 + hours daily at a desk and have reported mild wrist or forearm fatigue.
- Teams that standardise equipment – the multi‑device Bluetooth pairing simplifies shared workstations.
- Users who prefer low‑profile keys – the plunger mechanism feels quieter than mechanical switches while still offering a solid tactile bump.
- People with larger hands – the extra palm cushion on the mouse benefits users who need more support; those with petite hands may find the mouse slightly bulky.
If you suffer from chronic musculoskeletal issues, the devices can provide modest relief, but they are not a substitute for professional ergonomic assessment.
Pricing and availability
| Product | MSRP | Availability |
|---|---|---|
| M850L mouse | $49.99 | Direct from Logitech, major retailers – ships early June 2026 |
| MK880 keyboard (stand‑alone) | $69.99 | Same as above |
| MK880 + M850L combo (MK880) | $99.99 | Bundle includes both devices, slight discount over buying separately |
Logitech’s standard one‑year limited warranty applies.
Bottom line
The Signature Comfort Plus Series nudges Logitech’s office lineup toward a more comfort‑first philosophy. The built‑in palm cushion on the M850L and the dual‑foam wrist rest on the MK880 are tangible upgrades over the previous generation, and the price points remain competitive. For users who already enjoy Logitech’s ecosystem and need a modest ergonomic boost, the series is a sensible upgrade. Those seeking a full‑split or highly adjustable workstation will likely look elsewhere.
