Forget Amazon! I test office chairs for a living and you can get some way better deals when you avoid Amazon entirely

I've always found budget brand Sihoo offers some great office chairs for the price. This is one of the cheapest I've seen from the company, and ticks all the core boxes most people will need.

The C7 from FlexiSpot is one of my favorite office chairs. In our review, we found it delivered all-day comfort at an affordable price.

If you want serious comfort, Vari is always a good chair-maker to check out. This deal caught my eye since, alongside the usual bells and whistles, it boasts a Tempur-Pedic cushion, which Vari says "adapts to your body’s temperature and weight, then returns to shape when you stand."

Vari chairs are typically at the higher end of the price spectrum, so this is a great office chair deal right here, with an ergonomic design, plenty of adjustment mechanisms, and adjustable lumbar support.

FlexiSpot's premium upgrade on the excellent C7 - the C7 Max - gets a steep discount in the Prime deals. Loads of adjustments on offer here, including 5D armrests, tilt and recline, and adjustable seat and backrest.

I absolutely love this office chair for its blend of ergonomic comfort and relatively low price. In my review, I praised the comfort levels here, and find I can sit in it all day without any issues at all. Use code BF90 for the discount.

Designed for offices, but highly suitable for home offices, I found the OP300 was a great ergonomic office chair with a good amount of adjustment mechanisms and levers for tailoring the seating experience in my review. Use code BF30 for the full discount.

The FlexiSpot C7 is always worth checking out if you want a cheap ergonomic office chair. We found all the C7 series to be comfortable for prolonged sitting. For £10 extra, you can opt for the discounted wave design, which effectively splits the backrest and lumbar support into two for extra comfort.

Designed for greater back support, the BS8 meets all the core requirements I'd look for in a cheap office chair, particularly around the lumbar support area, which is adjustable.
