A colleague recently bought the jasper advance air plus for her home office (we work from home and in our early 30s) and recommended it. We sit for 8-9 hours per day. I tried out the jasper advance air plus and the jasper j advance chair and went with this one instead. Slightly cheaper but even not comparing prices I found thus one to have better lumbar support so was better for me. Came in a box with 4 screws and a Alan key, took about 10 min to put together, really not complicated. Have had for a week now and after a few tweaks adjusting seat height, angle, back support height and seat angle (all really good adjustable settings) I’m finding it really comfortable and supportive. Worth going in store to sit on the chairs for a few mins each but if you can’t, I’d gladly recommend this chair.

This chair is perfect for my work for home setup. It was super easy to assemble and really comfortable to sit in, even on days when I'm doing any overtime

The assembly of this chair was slightly inconvenient as I was trying to align the screw holes which took some time, although the entire assembly is straightforward. However, the chair itself is good and helps with my posture. When getting off the chair it raises itself slightly which I find to be a minor inconvenience, however I can handle this and it only seems to occur at the maximum height; this is the same as my old chair. The maximum height this chair raises to, for me, is perfect. I bought this chair because of its features and it has been AFRDI 6 certifed. Furthermore, it has a 10 year warranty (excluding upholstery) which is another reason I purchased this. I recommend this chair as it is reasonably priced.
