Buy SIHOO if...
SIHOO M18 Ergonomic Office
The SIHOO M18 is ideal for users seeking enhanced adjustability and long-term durability for their home office. If you fall between 5'6" and 6'2" and prioritize 2D adjustable armrests for precise comfort, along with the peace of mind of a 3-year warranty, this chair is an excellent choice. Its 330 lbs capacity and adjustable lumbar/headrest make it versatile for those who spend significant time at their desk and want better support without a premium price tag.
Buy XUER if...
XUER Ergonomic Office Chair,
The XUER chair is best suited for budget-conscious individuals who need reliable ergonomic support for daily work sessions of up to 8 hours. If you value a robust 330 lbs weight capacity, a comfortable S-shaped backrest for lumbar support, and breathable mesh, but don't require extensive armrest adjustability (as it's 1D only), this chair is a strong contender. Its slightly lower price point and focus on core ergonomic features make it practical for standard office tasks.
