Which is better for tall or heavy users?

The Doro C300 Pro V2. It is rated to 330 lbs and states a 5' to 6'3" height range, while the NOUHAUS tops out at 275 lbs with no stated height range.

Is the Doro worth the extra $110?

If you want self-adjusting lumbar support, seat depth adjustment, 6D armrests and a higher weight limit, yes. If you are an average-sized user on a budget, the NOUHAUS covers the core ergonomic features for less.

Which has better lumbar support?

The Doro's self-adaptive lumbar follows your back as you move and offers three support levels. The NOUHAUS uses a 3D lumbar pad you position manually, which some buyers find sits wrong for their height.

Which reclines further?

Both recline up to 135°. The NOUHAUS adds locks at three angles, which helps if you want to hold a fixed lean-back position.

Which is easier to live with day to day?

The Doro needs less adjustment because its support moves with you. The NOUHAUS rewards users who like dialing in armrests and lumbar by hand, but some owners report inconsistent caster rolling.
