What We Like
- The listing states a 400 lb capacity on a steel base.
- The seat carries an air pocket cushion with a flexible edge.
- The 3D Microknit back is classed as mesh, over a polyester seat cover.
Watch Out For
- The listing does not state an owner rating or a review count, and it does not give a warranty term.
- It is one of the pricier chairs on the site, so make sure the 4D arms, seat depth and tilt tension are features you will use.
At a Glance
Fully adjustable 4D arms, an adjustable seat depth and a weight-activated tilt with tension control come together in this Steelcase 3D Microknit chair, filed under Guest & Reception. The listing states a 400 lb capacity and does not state an owner rating.
Who This Chair Is For
- Meeting rooms and shared desks where each user wants to tune the arms, seat depth and tilt tension.
- Buyers who want a Steelcase mesh back with a stated 400 lb capacity.
Who Should Look Elsewhere
- Anyone with carpet at the desk, since the casters are the hard type.
- Sitters above 400 lb, because the stated capacity stops there.
Microknit Steelcase: arms, seat depth and tilt tension explained
A weight-activated tilt with adjustable tension and an adjustable seat depth are the core of this chair, and the arms add movement in height, width, depth and pivot. The seat edge is flexible and the base is steel on hard floor casters. The listing does not state a recline angle, a headrest or a seat height range.
Alternatives to Consider
Why consider: States a 12-year warranty, which this listing does not state, on a mesh-back chair with the same seat depth adjustment and tilt tension; its stated capacity is 300 lb against 400 lb here.
