I am sorry to tell you that this is my only recommendation and it costs about 1600 quid. I know that's not helping, so self saging.

You can get them used and refurbished for about half that, though still going from £99 to £800 is still likely useless for OP.

Staples I've found is very good for chairs, they have plenty rated for 24 hour use and so on.

What you're looking for is usually called a "draughtsman chair" or similar.

Having a taller chair puts more strain on the seat post if you put your weight off centre, I believe there are also stricter product safety regulations on higher chairs.
Both of these lead to the point that this height of chair needs a more compact seat base and limited recline, hence no one is able to make a tall chair that deviates far from the style of the one linked in the OP.

Thanks but not to worry, lads. I'm still not sure of the chair in OP and reckon I'll just continue to work from my bed because I don't have the leftover motivation.

Work will pay for it but that fucking parcel-force bloke who came to pick up the old chair woke me up at 7 today and I'm sure the seller will find a reason to refuse the refund just to put the icing on the previous saga.

I would never recommend buying them new, but Hermann Miller draughtsman's (as >>2733 points out) are almost unicorns. The flagship Aeron you can get at decent discounts from office dissolutions and bankrupticies but the "high chair" equivalents aren't anywhere near as popular in the start-up and small business market and thus not quite as common.

A further caveat is that these chairs have a lot of adjustabilty which is best done by an ergonomics trained person. If you're buying this for home use and don't have that expertise you're wasting money on micro-adjustments you'll likely use wrong so you are much better off not splurging in this instance.

How does one get trained in ergonomics?

I've done no research, but it certainly sounds like a three hour course Sandra from HR insists on going on to "enhance her skillset", and once she's done it you'll never be able to slouch again without her wagging her finger at you.

I'd rather have the twisted spine.
