Logitech K585 vs K860: Which Fits Your Desk and Devices?

Choose K585 for a compact, conventional keyboard with a phone holder and two-device switching. Choose K860 for its curved split layout, padded palm support and three-computer switching, provided its larger body fits your desk. Personal comfort still depends on your fit and preferences.

The buying question

Do you want a compact conventional keyboard with a phone holder, or a split keyboard with palm support and a third computer connection?

K585 combines a smaller conventional body and phone holder with two-device switching. K860 provides a curved split frame, padded palm support and three-computer switching in a larger body.

Quick verdict

Choose Logitech K585 Slim Multi-Device if

  • You want familiar unsplit keys and a number pad in the smaller body.
  • You alternate between a computer and a supported phone that fits the holder.

  • You need three prepared computer connections and have room for the larger keyboard.

When to skip: Skip K585 if retaining three computer pairings is essential. Skip K860 if you need the smaller conventional layout.
When the recommendation changes
  • A third computer needs its own prepared keyboard connection.
  • The phone case does not fit the K585 holder.
  • The K860 body and a separate secondary-screen position leave too little room for your mouse.

The differences that matter

Keyframe And Palm Support

Logitech K585 Slim Multi-Device

Low-profile, conventional unsplit keys and a number pad, without a built-in padded palm rest.[1, 2]

Logitech ERGO K860

Curved split keyframe with a built-in padded palm rest and palm-lift settings of 0°, −4° and −7°.[3, 4]

What this changes: Choose K585 to keep a conventional key arrangement. Choose K860 if you specifically want the split shape and adjustable palm support, allowing time to get used to that arrangement. Shape alone does not establish greater comfort or faster typing.[1, 2, 3, 4]

The better fit depends on your priorities

Phone Typing And Desk Layout

Logitech K585 Slim Multi-Device

Easy-Switch changes typing between two devices. The integrated holder can position a compatible phone at the keyboard; Bluetooth and Unifying are supported.[1, 2]

Logitech ERGO K860

Easy-Switch supports up to three paired computers using Bluetooth or Unifying. A short press selects a prepared channel. The keyboard has no built-in phone holder.[4, 3]

What this changes: K585 suits a computer-and-phone routine when the phone and case fit its holder. K860 adds a third computer connection; plan a separate position for any secondary screen. Neither channel switching nor the holder means simultaneous typing to every device.[1, 2, 4, 3]

The better fit depends on your priorities

Best for your routine

A computer-and-phone desk with conventional keys

Best fit: Logitech K585 Slim Multi-Device

Based on listed features, not comparative testing.

K585 combines two-device switching with a phone holder and the smaller listed body. Check phone/case fit and Bluetooth requirements; the holder is for positioning, so plan phone charging separately.

A split-key workstation with three computers

Best fit: Logitech ERGO K860

Based on listed features, not comparative testing.

K860 combines its curved split keyframe and padded palm rest with three selectable computer channels. Allow space for the full body and for any separately positioned secondary screen.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

A premium for K860 is easier to justify when you want its split frame and palm lift or will use the third computer channel. If a compact computer-and-phone arrangement is the priority, those additions may not suit your desk.

Price-history evidence is insufficient to recommend buying now or waiting.

Limitations

  • This comparison covers US Graphite K585 920-011479 and consumer ERGO K860 920-009166, both English US. ChromeOS editions, business packages and other language layouts are separate selections.
  • We did not test typing speed, comfort, noise, wireless reliability or battery endurance. No pain-relief or health benefit is promised.
  • K860 phone compatibility beyond the listed iPadOS support remains unconfirmed here. Check your specific phone, operating system and key layout before relying on it for mobile typing.

Questions shoppers ask

Will any phone or case fit the K585 holder?

No universal fit guarantee is established. Logitech lists the slot as 175.7 mm wide, 10.3 mm deep and 11 mm high. Those are holder dimensions, not a certified maximum for every phone or case; check your complete phone-and-case shape before buying.

Does K860 support phone typing too?

Its current US requirements list iPadOS 14 or later but do not establish Android or iPhone support. That omission does not prove incompatibility. K585 explicitly lists iOS/iPadOS 14 or later and Android 8.0 or later on a Bluetooth Low Energy host; mobile support is for basic functions, not desktop customization.

How much desk room should I reserve?

Start with the listed body dimensions: K585 is 373.5 by 143.9 mm across the desk; K860 is 456 by 233 mm. Then leave room for your mouse and any separate phone or tablet position. K860’s palm rest is part of that larger body.
