This was the only chair of this design, with the option for height adjustment. I read other reviews stating it was too low as a desk chair. I saw similar chairs had been modified with a rolling base and higher cylinder tube, since the mechanism to adjust height wasn’t on their chair base, they weren’t adjustable.So I ordered this one, along with a 25” heavy duty rolling base (I suggest a little larger from 26” to 30”) with wheels and a longer gas lift cylinder tube. When the chair arrived, as I put it together, I replaced the base with the rolling base and the new cylinder was too tall, so I used the one provided. The rolling base added 4” to the height, so now at the lowest setting it’s perfect for a normal desk or higher.I have a L-shape, sit-stand desk and 5 large monitors, I wanted to be able to recline back and work, and it’s much easier on the back. The seat padding towards the back is a little thin, if you work long hours. The seat cushion does have zipper access and there is enough room to add another piece of foam or to change it out with a slightly thicker and dense gel foam. I have a 2” gel chair pad that I put in above the foam, but I really need to just order thicker foam to replace what’s there. If you try this, just make sure you measure correctly. At some point, I may get a larger base and a little longer gas lift, but for now, it’s perfect.Also, many other recliners had a foot rest under the seat that can be pulled out. But they have just 2 thin bars to support the fully extended foot rest and look like they’d break easily. This one is much more sturdy since it’s more like a traditional recliner chair that lifts up. Reclined all the way back with leg rests up, you can almost achieve a zero gravity position.It was also fairly easy to put together, I followed advice about final bolt tightening and adjusting the chair before you completely tighten the bolts, which avoids any misalignments.Wish they had more colors, but the black is just fine.I also purchased a keyboard and mouse shelf which is on a swing arm and attaches to the cylinder of the chair and it makes it just so much better. At the moment, mine is attached to a pole on my desk. This attached to the chair, allows me to be farther back from my desk and with a few monitor tilts, totally comfortable to work while reclined. It’s totally worth it!!
