Logitech appears twice on this site: the ERGO K860 in ergonomic keyboards and the Lift vertical mouse in ergonomic mice.
The ERGO K860 keyboard. A wireless curved split keyboard with concave keys, a padded wrist rest and feet that set 0°, -4° or -7° of negative tilt, connecting by USB receiver or Bluetooth. It is the only keyboard in its hub certified by an ergonomics organization, United States Ergonomics. Logitech’s own figures — 54% better wrist support and 25% less wrist flexion than a standard keyboard — are its comparison, not an independent test. No regional layout is stated, and it had no US price when we checked.
The Lift vertical mouse. A 57° vertical mouse designed, Logitech says, to criteria set by ergonomists — not the same as an outside certification. It is for right hands, small to medium, which the listing says outright; the Anker states it does not suit small hands. It connects by Bluetooth or a Logi Bolt receiver, works with Windows, macOS, iPadOS, ChromeOS and Linux, and quotes the longest battery life in its hub, up to 24 months. The Graphite version uses 70% recycled plastic. About $70 when we checked — the highest mouse price in the hub.
Worth remembering. Neither design can promise less pain; comfort depends on your hand, your desk and how you set them up — should your elbows be supported while typing? covers the setup.
