Steelcase Criterion

You okay, so this is the Steelcase criterion chair. It's a really good chair, because it's really adjustable the trick is knowing how to adjust it.

I got a Steelcase Criterion recently, really liking it so far. I also tried a Leap in a store, and it wasn't agreeing with my back as much, at least at first try. I'm 35, my lower back can feel a bit stiff at times, especially in office chairs. This chair has adjustable back height.

Even if they are an older model (ex. Steelcase Criterion or Sensor, Herman Miller Equa, etc...) these will still likely be a better chair and hold a higher resale value when you go to move than anything in that price range new.

Go through a Contract Furniture Dealer, the kind that does large office buys. Might be called something different in the UK, possibly To The Trade. I'd recommend that you ask them to price out Bariatric task chairs, like the Steelcase Criterion, which are designed for the larger in mind.
