The Logitech Wave Keys is the gentlest way into ergonomic typing: a full-size 104-key board with a wave-shaped key bed and a fixed memory-foam palm rest, in a layout your fingers already know. Nothing is split, nothing is tented, and nothing has to be relearned. That is the whole idea.
That makes it a different proposition from the split boards further up our Keyboards list. A Kinesis Advantage360 or a Keychron Q11 physically separates your hands to open out your shoulders, and both take a week or two before your typing speed comes back. The Wave Keys instead curves a single conventional board so your wrists sit at a softer angle, and you type normally from the first minute. If your discomfort is mild, an ache after a long day rather than diagnosed RSI, that trade is usually the right one.
Within Logitech's own range it is the entry point. The ERGO K860 curves harder and adds a split-feel layout; the MX Keys S drops the ergonomic shape entirely for a flat, backlit, premium-feel board. The Wave Keys sits below both. Against the cheaper Perixx and Arteck options it wins on build quality, battery life and multi-device switching rather than on shape.
One thing worth checking before you buy, because nobody mentions it: at 37.6cm wide this is a genuine full-size board with a number pad, and a wide keyboard pushes your mouse further to the right. If you reach for the mouse constantly and it is your shoulder that hurts rather than your wrists, a compact or tenkeyless board will do more for you than any amount of wrist cushioning. If you live in spreadsheets, the numpad is worth the width.
Connection is Bluetooth or the bundled Logi Bolt USB-A receiver, with Easy-Switch across three devices, and it runs up to three years on the two AAA cells in the box. The graphite shell uses 61% post-consumer recycled plastic. Logi Options+ will remap the function row if you want it to, but it is not required, and the keyboard works fully without any software installed, which matters on a locked-down work laptop.
