It’s said that we spend, on average, about a third of our lives sleeping, which comes to about 10,000 days. 

Most of us probably spend a similar amount of time sitting. In this ever more digital age, our office chairs are basically our waking beds, cradling our bottoms and supporting our spines for countless cumulative hours.

So it’s worth putting in the time and effort to pick a good one.

Do you want dynamic lumbar support? Are you looking for an adjustable backrest? Would you prefer your chair to have 4D armrests, adjustable seat depth, and a premium elasticated mesh construction?

Of course you do. You’re not an idiot. And ergonomic chair specialist Sihoo has just saved you a lot of hassle by slashing the price of its Doro S100 ergonomic office chair for Amazon Prime Week.

You can pick up one of these bad boys in black right now for just $269.99/€269.99, which represents a massive $280/$280 discount. The white version will cost you a shade more, at $279.99/€279.99, but the saving is exactly the same.

In case you’ve never conducted any research into the world of high-end office chairs, here’s the lowdown on how a company like Sihoo operates. 

Prominent in the market for the last 12 years, Sihoo employs an R&D team of more than 100 experienced professionals in ergonomics, engineering, and wellbeing. 

Picture them now, with their lab coats and clipboards, hurrying around in Sihoo’s 10,000 square foot testing center as they strive to create the perfect chair for working, gaming, and being generally happy and productive while seated. 

It probably doesn’t look exactly like that as Sihoo HQ, but you get the general idea. 

All of Sihoo’s chairs—including the Doro S100—come with full BIFMA and SGS certification, but more importantly they all come with countless hours of expertise and testing.

Oh, and they look great.

The Doro S100 is like a work of a minimalist art, with thin, lightweight mesh upholstery, clean lines, visible springs, and a general sense of austere elegance. It does that thing of looking incredibly stylish by not ostensibly attempting to look stylish at all. 

In terms of specs, the Doro S100 comes with distinctive dual dynamic lumbar support, visible as two distinct spring-mounted sections that respond dynamically to your movement whatever your size and shape. 

The backrest, meanwhile, is easily adjustable to five different levels, supporting sitters at a range of heights, from 150cm to 190cm. 

There’s more adjustability in the seat, too, with a range of 5cm allowing you to ensure that your hips and thighs are well supported.

Finally, there are the all-important 4D armrests. A mainstay of premium office chairs, 4D armrests are adjustable in four directions. You can move them up and down, back and forth, and in and out, giving your arms a place to rest whatever your position and body type. 

If you’re tempted to treat yourself to a Doro S100 at its current bargain price, you may also be interested to know that delivery is free (unless you live in a particularly remote region), and so are returns within 30 days.
