Rather than the overall chair height range (where the top of the head rest ends), the height range of the seat base itself would be a useful dimension.
For example, my current pc desk has a pull-out shelf in permanent use ~55cm off the floor, to fit my legs under that shelf, I need to set the seat base at ~40cm.
Well done, you have a future purchase from me (once I find a place to live permanently!)
We didn't include this information as it is adjustable and they are all the same. and you can also buy an additional gas cylinder if you require more height.
They look to be approx 335-410mm in height from the floor
does the warranty cover stitching issues for the full two years?
