**Q: which dimensions are for the seat width and depth?**
A: The seat width is 19.5" and the seat depth is 17.75".

A: I have wiped it off with a damp cloth.

**Q: Dear Alera seller, where can I buy the arms for this chair?**
A: I have a new set I never opened I'll sell you for $25 plus shipping.

**Q: Can the back rest be adjust down to meet the seat?**

## Customer Reviews

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    very comfortable for such a cheap task chair.  pleasantly surprised.  minus one star for one construction fault I work around.
  

*by A***W on Reviewed in the United States on August 22, 2014*

I'd ravingly give this chair 5 stars easily except for a weakness in the construction.  I lean heavily back on any office chair I've ever had, and on this one, all the weight on the hollow back knob pressing against the hollow back of the chair causes it to literally start cracking.  The last one I purchased I did not heed this and the knob broke through.  I ghetto-rigged it on the inside with plywood and a lot of screws through it, because it was so comfortable to sit in for hours that I really loved the chair.  I got a new one, and I created a hardwood plate for the back of the chair to spread the weight along the back of it, and this prevented the back of the chair cracking but after nearly a year the knob itself ripped off.  Again, love the chair so much I went to a hardware store and purchased a bolt and washers and screwed it back together.Alera took the trouble to make an adjustable "stiffness" of the spring that makes the chair lean back (picture: underneath seat) as well as the usual tilt/lock bar (picture: sticking out the side of the chair) and you can adjust the height of the back of the chair.Alera: really well done on creating a very comfortable and very low costing chair with these three adjustabilities.  Please fix the one construction fault so I can give you 5 star.  I will keep buying these chairs.

    Cushions Hard As A Rock
  

*by A***R on Reviewed in the United States on May 9, 2020*

Looks comfortable in pictures but the fluffy looking cushions turn out to be hard as a rock.  It's a shame that a quality chair can not be manufactured.
