CHERRY KC 4500 ERGO — Wired Ergonomic Keyboard with Palm Rest, UK English, Black
Curved key fieldMemory-foam palm rest106 keys + numpadPlug-and-play USB-A
The CHERRY KC 4500 ERGO (JK-4500GB-2) is the gentle way into ergonomic typing. Instead of splitting the keyboard into two halves, CHERRY curves the key field so your hands meet the keys at a more natural angle, and adds a permanently attached palm rest with a memory-foam PU surface that supports the heel of the hand rather than the wrist joint. Everything else stays familiar: a full 106-key layout with a proper numeric pad, three hotkeys, and a single USB-A plug that works the moment you connect it. The body measures 456 × 217 × 35 mm in a matt black ABS finish, and the free CHERRY KEYS utility lets you remap keys to files, folders, macros or applications. In the box: keyboard with fixed 1.8 m USB cable and documentation.
Compatibility — check before buying:
Layout: UK English QWERTY has the tall Enter key, £ on Shift+3, and @ and " swapped compared with US layout. Letters and numbers are identical to US; if you need the US key shapes, ask us for the US International version. This is a one-piece curved keyboard, not a split or tented one: the adjustment is milder than a Kinesis- or R-Go-style split board, which is exactly why most people adapt to it in a day or two rather than a fortnight. The palm rest is fixed and not removable, so plan for a 456 mm wide footprint on the desk. It is wired only over USB-A with a fixed cable — there is no wireless option and no USB-C plug, so a USB-C-only laptop needs an adapter or a dock. CHERRY lists Windows for the CHERRY KEYS software; the keyboard itself types on macOS and Linux over standard HID, but the utility is Windows-only. There is no backlight. CHERRY does not publish the switch type or the keyboard weight for this model.
Best For
✓ Office users starting to feel wrist strain but not ready for a split keyboard
✓ Anyone who wants ergonomics without giving up the numeric pad
✓ Shared desks where a plug-and-play keyboard has to just work
✓ Accounting and data entry, where the numpad is used all day
✓ Replacing a flat keyboard used with a laptop stand or docking station
✓ Home offices that need a quiet, cabled keyboard
Key Features
Curved key field, familiar layout
The key rows fan out to match the natural arc of your fingers, so your wrists rotate less — but the letters, numbers and numpad stay exactly where you expect them.
Memory-foam palm rest
The integrated palm rest is finished in memory-foam PU: it supports the heel of the hand so your wrists are not resting on a hard desk edge between bursts of typing.
Full 106-key layout plus 3 hotkeys
Nothing is removed to make room for the ergonomics — you keep the function row, the navigation block and the numeric pad, and gain three dedicated hotkeys.
CHERRY KEYS remapping
CHERRY’s free Windows utility turns keys into shortcuts for applications, folders, text blocks or macros, which is where an office keyboard actually saves time.

Frequently Asked Questions
Is it a split keyboard?
No. The KC 4500 ERGO is one piece with a curved key field — a milder change than a split board, which is why the adjustment period is short. If you want a true split, ask us about the R-Go and Bakker Elkhuizen split models.
Can I remove the palm rest?
No, it is part of the housing. Allow 456 mm of desk width and about 217 mm of depth.
Does it work on a Mac?
It types over standard USB HID, so yes for normal typing. The CHERRY KEYS remapping software is Windows-only, and the modifier keys are labelled for Windows.
Which layout is this part number?
This one is UK English. CHERRY builds the KC 4500 ERGO in several national layouts under separate part numbers — tell us which one you need and we will confirm it before ordering.
Singular Expert Insight
The KC 4500 ERGO is the model we recommend when someone wants relief from a flat keyboard but has to keep working at full speed from day one. If your strain is already significant, a fully split board is the better investment — talk to us first. Browse the rest of our
keyboards or pair it with one of our
wireless mice for a matched desk setup.
