Frequently Asked Questions

Common questions about this comparison

Which chair is better for heavier individuals?

The SIHOO M18 is explicitly rated for users up to 330 lbs, making it the safer and better choice for heavier individuals. TRALT does not specify a maximum weight capacity, which is a significant consideration for larger users.

What's the main difference in warranty?

The TRALT chair offers a longer 5-year warranty, providing extended peace of mind and product security. The SIHOO M18 comes with a 3-year warranty, which is still substantial but two years shorter than TRALT's offering.

Which chair offers better armrest adjustability?

The SIHOO M18 features 2D adjustable armrests, allowing for height and pivot adjustments for more personalized comfort. The TRALT chair has more limited 1D armrest adjustability, typically only moving up and down.

Is the TRALT's PU leather seat a significant advantage?

The TRALT's PU leather seat offers a different feel and can be easier to clean or more resistant to stains compared to an all-mesh seat. However, an all-mesh design like the SIHOO M18 typically provides superior breathability.

Which is better for a wider range of user heights?

TRALT states a fit for users between 5'2" and 6'4" (62-76 inches), which is slightly broader than SIHOO's mentioned fit range of 5'6" to 6'2" (66-74 inches).
