I see this Prime Day office chair deal every year – but I haven’t tired of recommending it yet

When shopping around for Prime Day deals, the usual suspects are Amazon devices, tech and home appliances. You might not necessarily think to look for an office chair. However, this deal is one that I expect to see every year without fail. And this Prime Day (23-26 June), I haven’t been disappointed. 

The Sihoo M57 office chair (in grey) is currently £161, down from its usual £230 price tag. That’s the cheapest it’s been in recent memory.

When it comes to ergonomic office chairs, you can spend an awful lot. The Sihoo M57, however, represents fully adjustable ergonomics at a competitive price – even when it’s at its RRP of £230. It’s the top budget pick in our best office chairs roundup.

In addition to the standard height adjustment and back tilt, the M57 has adjustable lumbar support, fully adjustable arms and a headrest. And with a mesh design, it’s cool and comfortable throughout the entire working day. Just ask our very own Managing Editor, Will Georgiadis, who sits on it every week in his own home office. 

As I said, I see the Sihoo M57 discounted every year, during Amazon’s Spring Sale, Prime Day, and Black Friday. So, you might expect it to be a bit of a diminishing return by this point. Maybe slightly, but we can’t turn our noses up at a good deal, even when it’s as predictable as this one. 

What’s more, at £161, this deal is actually slightly better than it was during last year’s Prime Day Sale (£170) – provided you buy the lighter grey version. 

Already sitting comfortably? We’ve got the drop on plenty more deals over on our Prime Day Hub, including savings on fans, smartphones, TVs and more.
