What We Like
- The arms are 4D and the listing marks them as flip-up, so they can be swung out of the way at the desk edge.
- The headrest adjusts in height and angle, and the lumbar support is described as dynamic.
- Its Ergo Score of 55 is one of the higher scores in its category, helped by full marks on the armrest, lumbar, headrest, certification and base lines.
Watch Out For
- Only 15 reviews are posted, averaging 4, so there is little owner feedback to lean on yet.
- The listing does not state a warranty term, a recline angle, seat depth adjustment or tilt tension, and it does not give a seat height range.
At a Glance
Dynamic lumbar, an angle-adjustable headrest and 4D flip-up arms are what the SGS-cylinder Ergo3D offers, along with a stated 300 lb capacity.
Who This Chair Is For
- Buyers who want 4D arms that also flip up, with a 300 lb capacity stated on the listing.
- Shoppers who want both a BIFMA and an SGS mark named on the listing.
Who Should Look Elsewhere
- Anyone who wants a stated warranty term before buying, since the listing does not state one.
- Sitters who want to fine-tune the lumbar: it is described as dynamic, and the listing does not state height or depth controls for it.
How the SGS-cylinder Ergo3D handles arms, lumbar and headrest
The arms carry the most detail: the listing marks height, width, depth and pivot adjustment, which makes them 4D, and says they flip up. Lumbar support is described as dynamic, but the listing does not state height, depth or tension controls for it. The headrest moves in height and angle. The title names an SGS certified gas cylinder, and the listing does not state seat depth adjustment, a recline angle or a tilt tension control.
Alternatives to Consider
Why consider: Lists lumbar adjustment in both height and depth, which this listing does not state, and has 1149 reviews averaging 4.7 against 15 here.
