Frequently Asked Questions

Common questions about this comparison

Which chair is better for bigger and taller users?

The ProtoArc EC200 is better, supporting 350 lbs compared to XUER's 330 lbs. Its design specifically targets "Big & Tall" users for extended comfort, offering a seat height range of 16.0-20.5 inches, making it more suitable for a wider range of larger body types seeking robust support.

What's the main difference in adjustability between the two chairs?

The ProtoArc EC200 offers superior adjustability, featuring 4D armrests and a 3D adjustable headrest, alongside a sliding seat. The XUER M18-M145 has 1D armrests, limiting vertical movement only, making ProtoArc significantly more customizable for varied postures and user preferences.

Is the price difference worth it for the ProtoArc EC200?

The ProtoArc EC200's premium price is often justified by its 12-year warranty, higher weight capacity (350 lbs), and superior 4D adjustability for armrests and headrest. XUER offers a 1-year warranty. For long-term investment, comprehensive customization, and durability, the ProtoArc offers better value.

Which chair provides better lumbar support?

Both chairs offer lumbar adjustability. XUER highlights an "S-shaped backrest" and adjustable sponge lumbar support. ProtoArc also features lumbar support and is noted for being "highly adjustable," which suggests it may offer a more precise and customizable fit for individual lumbar curves and preferences, enhancing 8+ hour comfort.
