Check Current Price

Overall, we like Sihoo office chairs and think it’s a great buy if you’re looking to add a modern, comfortable and ergonomically designed chair to your office set up. We even include this chair in our list of the best office chairs for under $300.

But it’s not the perfect chair for everyone. And, like many other mass-produced office furniture products, there have been some issues with faulty parts.

For example, as we’ll mention below, the headrest is both height and tilt adjustable. But these features have been found to either not last too long or be defective with some users. Also, the pneumatic gas cylinder has been an issue for some customers. 

Luckily, Sihoo offers solid and responsive customer support, as well as a 3-year period after purchase for all parts replacement. While their standard warranty is only 1-year, this added protection for parts is an added layer of protection and customer assurance. 

Also, unlike other similarly priced ergonomic task chairs, such as the WorkPro 1000 series, the Sihoo does not offer a sliding seat depth adjustment. If this is important to you, be sure to check out some other options.

Sihoo Office Chairs: Alternative Models

In addition to the popular ergonomic chair option covered in this review, there are a couple other popular models in the Sihoo range that are worth a look.

Let’s take a quick look to compare these with the ergonomic model.

Sihoo Reclining Office Chair

SIHOO Ergonomic High Back Office Chair with Adjustable Lumbar Support, Reclining Office Desk Chair, Computer Mesh Chair with Footrest (Black)

First we have the reclining ergonomic Sihoo model. This is a slight step up in price. It also offers a bit more functionality. For instance, there is a little more tilt range (90 to 170 degrees) and a high backrest.

But the main difference is that the reclining model has a retractable footrest. So if you really want to kick your feet up during th ebay and relax, this model is worth a look.

Otherwise, in terms of comfort, ergonomics, support and adjustability options, this model is very similar to the base ergonomic option reviewed in this post.

Sihoo Mesh Task Chair

Sihoo also makes a budget-0friendly mesh task chair. If you have a smaller space (i.e. bedroom, dorm room, small office at home), this could be a good option.

The Sihoo mesh office chair has a cool liftable and reversible armrest feature. The cushion is comfortable and thick, at 2.5” of high-density foam.

It has a 110 – 120 degree tilt range with the ability to lock into place and control the tension. The basic mesh model also has quiet and smooth rolling PU casters, along with an 8 cm height range to adjust to your needs and a 360 swivel rotation.

There is no headrest with this chair and the color is a lighter gray tone. If you need a low to mid-back model that won’t break the bank, it’s worth a look.

The mesh model does still have a separate lumbar support with a 1.2” height adjustment range and an S-curve profile though the mid back portion of the chair to provide basic ergonomic support.

And, like the main ergonomic model, it features a swift breathable mesh material to keep your back cool.
