The SIHOO M90D packs in plenty of features and adjustability without breaking the bank.
The SIHOO M90D is an ergonomic office chair from the Chinese office furniture maker SIHOO which was founded in 2011 but only began selling its products overseas in 2018. The company has built up a lot of momentum in the time since and it now sells a wide variety of office chairs on its website as well as on Amazon. While the model we tested has a mesh back and a padded seat cushion, SIHOO also sells a version of this chair with the same design which has a mesh seat cushion. Ergonomics is the main focus of this chair and even the box it ships in features a diagram showing you how to correctly sit in it to avoid putting unnecessary stress on your back. The SIHOO M90D’s best feature is its adaptive lumbar support bar which adjusts on its own to ensure that your lower back is supported when using it. Elsewhere, the mesh back keeps you cool when working and its armrests can be turned inward or outward. Pulling a lever at its side out lets you recline while pushing it down lets you raise or lower the chair’s height. While you could save a few bucks on a budget model instead, for just a bit more the SIHOO M90D gives you the experience of sitting in a premium office chair without breaking the bank. The SIHOO M90D is available for $359 on the company’s website at the time of writing but it can also be purchased from Amazon for $369 with a $29 coupon that brings the price down to $340. However, Amazon only offers this office chair in black and gray while there is a two-tone red option (red back and headrest with a black seat) in addition to black and gray available on SIHOO’s website. If you like the design and features of the SIHOO M90D but prefer an office chair with a mesh seat as well as a mesh back like with the X-Chair X2, The SIHOO M90C may be what you’re after instead and it’s even a few dollars cheaper at $356. It’s worth noting that the SIHOO M90C is only available in black and gray though. The mesh backrest of the SIHOO M90D immediately draws your eye due to the fact that SIHOO decided to add a pattern to it. While some may prefer a mesh backrest without a pattern, this design decision is definitely unique to this chair as we’ve yet to see something similar from other office furniture makers.
