Comfort is key with Logitech keyboards

Tap happiness

2 million keystrokes. Every day.

That’s how much the average person types every year, according to a study by Harvard. (Dennerlein 2006)

If you sit at your computer hour after hour, day after day, all those key presses can really add up. Fortunately, you can do something about it. Logitech keyboards have a variety of comfort features to help keep your body happy.


Comfort Wave Design: Curve + Wave + Palm Rest

Your fingers vary in length—but most keyboards treat them all the same. Our Wave keyboards have a gradual wave-shaped contour to support the varying lengths of your fingers and keep the pressure off your fingertips.

To keep you from having to twist into an unnatural position when you type, we threw in a curve. Gently curving rows of keys support the natural resting position of your hands without splitting the keyboard. After all, you shouldn’t have to relearn how to type to be comfortable.

A cushioned, contoured palm rest helps position your hands comfortably on the keyboard. Plus, it gives you a cushy place to rest your palms when you’re not typing.

Perfectly PerfectStroke

Logitech PerfectStroke™ key system combines the benefits of a laptop keyboard with those of a stand-alone keyboard to give you a perfectly pleasant typing experience.

Clickety-clack. For those of you old enough to remember, it isn’t the sound of that old electric typewriter that you miss so much, it’s the way the keys felt under your fingers.

The Logitech® Unifying receiver takes convenience a step further.

The Logitech® Unifying receiver is a tiny, leave-in wireless receiver. Smaller than most coins, the Unifying receiver not only makes it easy to use a wireless keyboard, mouse, or number pad, it also works with up to six devices.

Powering your wireless keyboard

More power to you

No one likes to run out of batteries. It’s a hassle. Scouring the house for new ones. Finding two that still have juice. Even making an extra trip to the store. At Logitech, we’re doing everything we can to make the hassle of replacing batteries hassle-free.


Batteries? What batteries?

Wireless keyboards let you avoid the inconvenience of cords. But unlike a corded keyboard (which is powered via USB and your computer), wireless keyboards use batteries, and batteries do run out of power.

Don’t even want to think about changing batteries? We’ve got just what you need. You can choose a keyboard with a battery life of 15 months—or even three years—and practically eliminate the hassle and expense of changing batteries.*


Charge on

If rechargeable is more your style, we’ve got those too. You just put your keyboard in its charging base. It’s that easy. (Plus it’s good for the planet.)

* Battery life calculation based on an estimated 2,000,000 keystrokes/year in an office environment. User experience may vary.
