I've looked everywhere, and these are the best office chair deals this Prime Day in October

Sihoo M18: $149.99 $129.99 at Amazon
Save $20: I just reviewed this chair, and I absolutely love it. It's the number 1 budget chair that I would recommend to anyone. (In fact, I'm getting in the orange model as a secondary chair, I love it so much). But why? It's ergonomic, stylish, comfortable, and all for well under £150. In fact, with £20, it's just £130. Bargain.

Price check: £179.99 at Sihoo

Boulies M460: $369.99 $299.99 at Boulies
Save $70: As ever, if you're willing spend a little more in Prime Day, you're likely to save more. Here, the excellent Bioulies EP460 has $70, bringing it to under £300. I've also just reviewed this chair, and think it's a beauty. It's not the prettiest in the world (I'm not a massive fan of this style of lumbar support), but if you like the look of it, rest assured it's a cracking ergonomic chair.

Branch Verve chair: $599 $549 at Branch
Save $50: You can get $50 off the monochrome version of the Verve chair only at Branch's official website. Over on Amazon, that model is going for $589 with other colour models going for $639 – which is crazy, as again you can go direct to branch and get the colour options for $599. This in one serious good looking chair, but it's also really comfy and ergonomic too. I love it, and have the white version in my work office.

Secret Lab Titan Evo: $639 $549 at Secret Lab
Save $90: This is my pick of the best ergonomic gaming chairs out there. It's very comfortable, and very stylish – if you like that gaming chair aesthetic. It's adjustability is supreme too, so you can definitely find that ideal position for when you're working or gaming.

Herman Miller Aeron: $790 $615 at Amazon
Save $160: This deal is also improived - it was down to $629 a few days ago, so that's a few more bucks off the asking price. The Aeron is a classic office chair, and it's been popular with creatives (and presidents for that matter) for decades. When I reviewed it, I was blown away at how comfy it was, and how beautiful!

X-Chair X4: $1,349 at Amazon
Right now there are no discounts on this exceptional chair, but I wanted to tell you about it, as I think it's the best of the best when it comes to executive leather office chairs. I'm hoping that the price will come down from $1,349 at some point this Prime Day, so come back soon if this is the one you want.
