Frequently Asked Questions

Common questions about this comparison

Which chair is better for heavier users?

The Duramont chair is better for heavier users, supporting up to 350 lbs, compared to the SIHOO M18's 330 lbs capacity. It offers more robust support for a wider range of body types.

What's the main difference in lumbar support?

The Duramont features advanced 4D lumbar support for precise lower back adjustment. The SIHOO M18 offers general adjustable lumbar support, but not with the same multi-directional customization.

Is the Duramont worth the higher price?

The Duramont is $29.01 more expensive, but it offers a higher weight capacity (350 lbs), more advanced 4D lumbar support, and a longer 5-year warranty, which could justify the extra cost for some users.

The SIHOO M18 offers 2D armrests, allowing for height and forward/backward adjustments. The Duramont has 1D armrests, which only adjust for height, making SIHOO more versatile here.
