Do give a hard thought whether you're saving money in the long run.
If you develop spine issues while using this chair thinking that paying extra for the allegedly "ergonomical" claims it'll be real unfortunate.
I'm not saying it will happen and I do not with on it to happen to anyone. Depending on the severity of a slipped disc, it will affect your ability to exercise or even sit AND stand... Compounding to more problems yada yada yada...
That being said, if you're thinking of the short run, it just doesn't make sense too.
(Using an IKEA chair for the sake of comparison, "Markus?")
The price is lower.
The comfort (not sweaty/sticky when you come into contact) is better.
The durability is better (fabric VS peeling PU leather)
And if you have to avoid having bare skin come into contact with the chair when you use it. When you have to make sure air con is on when you use it. And any other compromises that I cannot really think of now.
It's like equivalent to buying a branded handbag but cannot use? You get the drift? It becomes a fashion/status symbol, at the cost of your wellbeing.
Long story short, consider whether you're paying for more than you think.
From unnecessary inconveniences, to constant irritation, and hopefully not a physical price.

Have tried IKEA chairs, bought into marketing hype and misinformation of some of the gaming branded chairs, regretted, developed skipped disc. Spent a fortune to buy a chair that does not hurt as much. Still suffering from pain.
